==== Problem Sensors (as of June 2008) ====
* Met look good except precip.

Replace Batteries:
[[Image:K3-battery.gif|400px]] 
Check Precip Bucket Wiring:
[[Image:K3-precip.gif|400px]] 
Post Script (June 2008) the Pulse port for the precip bucket had gone bad. So, bucket was re-wired into a control port (after replacing the cable that we then learned was still intact).

New snow sensor looks great:
[[Image:K3-snow.gif|400px]] 
Check Soil Temperature 55 cm bgs (9th thermistor).

==== Problem Sensors (as of June 2008) ====
* Meteorological Sensors look great
* Radiation Sensors look great
* Judd snow sensor looks good, too: 
[[Image:K2-snow.gif|400px]] 
Although I wonder what the deal is with the drift (hysteresis) and what might have caused that midwinter spike.
* Look to see if 30 cm bgs Soil Moisture has become disconnected (loose wire)
* Look at YSI thermistors again

=== Site To Do List ===
* Look for 6 hr gap of data 2007 day 162 600 to 1200 (probably an rsync gap)
* Another data gap 2007 day 255 600 to day 258 1900 (possibly a combo data gap: rsync plus program change)
* Look to see if 30 cm bgs Soil Moisture has become disconnected (loose wire)
* Look at YSI thermistors again

==== June 2008 Trip ====
* Download Data
* Send new program (snow sensor)
* add net radiometer

==== Problem Sensors (as of June 2008) ====
* Met Sensors look good.
* All Soil sensors are broken (animal chew primarily)
* Snow is odd but perhaps okay. [[Image:K1-snow.gif|400px]]
June 14 trip follow up: The snow arm came undone (I'm guessing time-wise early in the winter). So, the data is probably bad until we can figure something else out for this site.

Seward Peninsula Sites

2008-06-20T23:44:17Z

137.229.51.127: /* Trip Itineraries */

==== Trip Itineraries etc.====
* [[2007 September Nome Trip]]
* [[2008 June Nome Trip]]
* [[ General Site Checklist]]
* [[Storage Inventory]]

====Sites Background====
As carry over from the ATLAS and HARC projects WERC maintains a network of telemetered data stations on the Seward Peninsula. Archived data is currently found on the [http://www.uaf.edu/water/project/atlas/atlas.html UAF WERC site]

Principal Data site, Council Area:
[[C1 Grid]] (near [http://www.udel.edu/Geography/calm/data/data-links.html CALM site U27]), active
[[C2 Blueberry]], active
C3 Guy Rowe, inactive

Principal Data site, Kougarok Area:
[[K1 Burn]] site, active
[[K2 Met]], active
[[K3 Mauze]] Gulch (near [http://www.udel.edu/Geography/calm/data/data-links.html CALM site U28]), active

We use radio telemetry to communicate with our stations out on the peninsula. So, there are several radio repeaters in that list, too. They are:
[[Anvil]] Mountain (near Nome)
[[Skookum]] Pass (near Council)
[[Kigluaiks]] (in Kigluaik Mountains across the valley to the south of Kougarok)

In addition there are several other sites:
[[Snake]] River (outside Nome on Nome-Teller Highway)
[[Kuzitrin]] River (60+ miles up the Kougarok Road from Nome)
[[Niagara]] Creek (~1 mile from K2 Met)

See most of them on a map here:
[http://www.uaf.edu/water/projects/atlas/atlas.html Site Map]

For reference, Nome is above the 'i' in Council. Also mentioned on that page are some sites in Ivotuk. Don't worry about them. They are no longer active.

====Project Background====
Originally there were three Council sites, C1, C2, and C3. Each was selected to be in a different type of landscape but C3 kept getting attacked by bears so we eventually removed it. C1 is called C1-Grid because it is located in the valley bottom near Council along the perimeter of a CALM 1 km x 1 km active layer grid. So, the meteorological station was set up to complement the field data collected on the CALM grid. In terms of importance to the original project it was a secondary station so the data elements collected there are basically: Air Temperature / Relative Humidity (1m & 3m), Wind Speed (1m & 3m) & Wind Direction (3m), Net Radiation (in summer), precipitation (in summer), snow depth, soil moisture (vertically profiled), and soil temperature (vertically profiled). The station is also a shorter 3 meter tower.

===Council Sites===
The blueberry site is located on Blueberry Hill to the SW of Council. It is the primary site for the Council area so has more sensors and the tower is a 10 meter high setup. In addition to the sensors mentioned for C1 there is also up facing shortwave & longwave radiation, and down facing shortwave & longwave radiation sensors. Wind speed & AT/RH (as a single sensor) are also measured at more heights than at C1 (1m, 3m & 10m). In 2007 I made some changes to the station. In the past longwave radiation was measured using a battery. However, it was a lead-mercury battery, which is considered hazardous and has been discontinued so I re-did the wiring. This will be reflected in the data as a couple extra data columns that appear last year. Blueberry is across the Niukluk river (I think that's the river, not 100%) and is sometimes unreachable in fall. So, we weren't able to get across the river to remove the net radiometer in Fall 2007. Data for it shouldn't be trusted much past October 1st though because once the snow falls or frost accumulates on the domes that protect the radiation sensor.

On a similar note, the precipitation gages are out year-round but we only record summer rainfall. So, you should mark with '7777' the winter time of year. For measured precipitation I don't generally count it until the air temperature is consistently above freezing. It's kind of subjective on the shoulder seasons figuring out what is snow vs what is rainfall and if you don't feel comfortable with that, I'm happy to look over the data and define select which points to include and which to exclude. It may sound like we're doing something funky but we aren't. The tipping bucket rain gage is only designed to measure liquid precipitation. So, when snow accumulates in the bucket no measurements are recorded until the bucket temperature gets above freezing to melt the snow in the bucket. Since those gages are just used in the summer then we exclude all solid precip that may melt in and be counted at the data logger.

===Kougarok Sites===
K1-burn is another secondary site. It is located on an area burned by an old tundra fire up on a low sloping bench above the Kougarok river. The vegetation in this area is dry tussock and grasses. Much of the organic soil layer burnt off in the fire so recovery has been slow. This site gets visited fairly frequently by animals so you'll see most of the soil moisture sensors have had their cables eaten, as has also happened to the soil temperature sensors. This site is quite similar to C1 that I talked about earlier in terms of sensor setup. In the fall of 2007 we added a snow depth sensor to the site so that will be a new thing. I'm not sure about its reporting though.

K2-met is the 10 meter tower for the Kougarok area. It is located on very wet tundra 300 meters or so up slope from the Kougarok river, so down in the valley. It is a full site similar to C2 although it also has a snow sensor installed. A broken, older sensor was replaced with a newer one in fall 2007.

K3 mauze is located at the perimeter of the Kougarok area CALM grid. It is another 3 meter tower. This site has been hammered by the bears in recent years so some sensors are in and out in terms of their quality.

===Discussion of the Station Data===
So, that's a short bit of background on the stations. The data on the CD I gave you is predominantly archived data or data that has been through some level of processing. You can find the up to the day data here:
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-blueberry
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-c1-grid
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-k-burn
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-k-met
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-kmauze

Those are all quite large at this point text files. Let me know if you find any gaps in the data. Sometimes there is trouble with the back end connection between the UAF webserver and the computer that retrieves this data over the radio network from Nome.

So, when you look at the data there it will probably look like a bunch of not real helpful numbers. Plus you'll see an Array ID at the start of the line which seems to alternate each hour. That is because the meteorological data arrays are mixed together withe subsurface data arrays. It's kind of a by product of the data logger we use. The design for them was done in the early 90s or late 80s so the electronic data storage architecture is robust but perhaps a bit primitive compared to the computers of today. So, to split out all the data I should have included on that cd a directory called 'batch' or 'bin'. If you look in there you should see some .bat files which are dos batch files. I don't know if you're using linux or windows, if you're using linux then pop open .bat file and you'll see 'grep .........' you should be able to change the directory paths there (I can help if you have questions about this) but these little batch files basically read through the data above (e.g. atlas-blueberry) and pull out all the met data arrays and then all the soil data array lines and dump them into different files. So, when you mention seeing different data files in the CD I gave you, the data is in various steps of processing. Oh, also, if you are using a windows computer (as I am for the data processing) then you should have cygwin installed. It's a program that gives you many of the free utilities that come with linux/unix/debian (most helpfully for us today, grep). You can download it here if you need:
http://www.cygwin.com

So, if you're using windows, just modify the batch files. I like to use this program:
[http://www.context.cx Context]
for viewing text files. I find it much more useful than notepad, but if you have a favorite text editing program, feel free to use it. Anyway, if you're using windows you'll need to modify the batch file to grep out the 2007 data I think. The general format for the grep command is:
grep [text string to search for] [input data file] > or >> [output data file]
c:\cygwin\bin\grep 228,3018,2007 "c:\data\atlas\c1-grid\atlas-c1-grid.txt" > "c:\data\atlas\c1-grid\c1-grid_228-2007-soil.csv"
You'll see both '>' and '>>' in the batch files. '>' means put all the data line matches into the output file and create a new file each time. '>>' means put all the data line matches into the output file and append them to the end of the file if it already exists.

So, you'll need to change the paths (e.g. 'c:\data\'), to whatever you're using. I like
c:\data\project\station_name from windows or /home/bob/data/project/station_name from linux but totally your call on how you organize. From linux the line above would like more like this:
grep 228,3018,2007 "/home/bob/data/atlas/c1-grid/atlas-c1-grid.txt" > "/home/bob/data/atlas/c1-grid/c1-grid_228-2007-soil.csv"

So, when you see stuff like this:
CD/atlas/C1-grid/c1-grid_123-2006-met.csv
CD/atlas/C1-grid/c1-grid_123-2007-met.csv
CD/atlas/C1-grid/c1-grid_228-2004-soil.csv
etc. etc.
That is output from the grep program. the 123/228 references the array ID. So, that file contains met data from 2007 from this file:
[http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-c1-grid C1 Data File]
Here's a sample line:
123,3018,2005,1,100,-0.47,-0.176,97.7,96.1,3.639,162.7,4.414,92.7,0,-2.046,12.35

I see for some flies the '123' has been replaced by the regular date & time. But that's probably the only change in the file. I would have done that if I was just checking things out.

So, moving forwards a bit, my rough method for processing the data is this:
# download data off website
# use GREP to separate out by data line type and year using the batch file for dos.. or if you use linux then you can actually edit the .bat files to be the correct path (like I mentioned above) and then from the command line type this: chmod u+x c1-grid.bat this will allow you to just type './c1-grid.bat' just as I have been doing but you'll do it from linux rather than windows.
# open in excel or use a program I wrote to process the data (more on this below)
# view the data with a data visualization program I used Origin but Excel is semi okay (origin is nice because you can quickly change the time scales) or if you have another program you really like like matlab that's fine, too.
# delete bad data that is apparent through using the visualization program (replace with '6999')
# have someone else do a final check (like me probably)
# post data to the internet

'process the data' is pretty nebulous. I have a program I wrote which converts thermistor resistances (soil temperature data) from resistance to temperature and then formats the data as it should look on the web. That's the main reason you see so many similarly named files. Some are from step 1, some are from step 2 etc. So, that is probably a bit confusing. But for you, probably using a spreadsheet program like excel or whatever you're most comfortable with is better. You can find header information for what is in each column of the data file. The other main bit of 'processing' that happens is to correct the net radiation data for wind. I can dig that equation up for you if you can't find it in those spreadsheets.
So, also along the process the data lines, some things you'll want to look out for:
# missing lines of data... make a note and check with me if you find any
# repeated lines of data... more likely to find due to the rsyncing process (the way the uaf website talks to the server downloading data from the radio network).
There are a couple ways of converting julian dates into regular. You could use these programs I've written for visual basic:
http://werc.engr.uaf.edu/mediawiki/index.php/Excel_Macros
or, another way is this:
a) type into a cell '12/31/06'
b) change the format of the cell to number.
c) if your data is in the format column 1 is the date you'd like, column 2 is the year, column 3 is the day, column 4 is the hour then in column 1 you can print (using data for 2007) '= 39082 + b1 + c1/2400' then format this column as a date & time and you'll be in business. Do some simple boolean stuff to check for gaps of data or, just create another column that has as the first cell '1/1/07 1:00' then the second row in the column '=a1 + 1/24' then look to see if the calculated date (mentioned first) ever varies from the second method. If it doesn't you're golden. If they do vary then you can track down where the problem is. In general, if there is multiple lines of the same data (or so it looks like) I will delete the first instance and keep the last. The reason for this is related to the radio telemetry. Some of the connections are quite weak so we don't always get the data on an hourly basis. Sometimes we'll get half the line so we'll need to get things resent later (with regard to the radio network and data retrieval from the data loggers).

I guess another note on the array IDs. The met data and the radiation data are contained in the same array ID line. The soil temperature and soil moisture data (most of which has broken sensors) is in a separate array ID. That is the 123, 127 etc. that you wonder about below.

Well, I've written a book, maybe I will post this to our wiki and we can go back and forth on there, too. Totally let me know if you have any questions. I'll be in town through Friday (just learned) so I should be able to help more in the short term than the medium term. thanks

============== Part 2 ===================
Here's a bit about the radiation. I will get you more calibration values once we're back from the June trip the week of 6/16.

So, in the data files you've looked at off the internet is the output voltage in millivolts as recorded by the data logger. To get from milliVolt output from the data logger to Net Radiation in Watts / m^2 you'll need to do a couple things:
1) correct for wind speed.
2) apply the sensor specific calibration factor (positive or negative depending on sensor output)

Via this manual (pdf page 5 document page 3):
Net Radiometers -- REBS Q-7.1 (Radiation Energy Balance Systems)
http://www.campbellsci.com/documents/manuals/q-7-1.pdf

Are these wind speed correction equations (where wind speed in in meters per second as we have at our stations):

Positive Wind Speed Correction Factor:
Wind_CF_Pos = 1 + (0.066 * 0.2 * 1m_Wind_Speed) / (0.066 + (0.2 * 1m_Wind_Speed) )

Negative Wind Speed Correction Factor:
Wind_CF_Neg = (0.00174 * 1m_Wind_Speed) + 0.99755

So, if Net Radiation (in mVolts as recorded by the data logger) is positive use this equation:
Corrected_Net_Rad = Wind_CF_Pos * Uncor_Net_Rad * Pos_Calib

If Net Radiation (in mVolts as recorded by the data logger) is negative use this equation:
Corrected_Net_Rad = Wind_CF_Neg * Uncor_Net_Rad * Neg_Calib

Here's the equation for C2 as it looks for me in Excel:
=IF(ABS([NetRadiometer Cell])<> 6999,IF(L4087>0,9.15*[Net Radiometer Cell]*(1+(0.066*0.2*[1 meter Wind Speed])/(0.066+0.2*[1 meter Wind Speed])),11.13*L4087*(0.00174*[1 meter Wind Speed]+0.99755)),7777)

So, given all that you need one more thing, the calibration values for positive and negative calibrations. Here's a first batch and I'll get you some more after we come back from out trip in a couple weeks.
C1 Grid:
Positive Calibration: 9.18
Negative Calibration: 11.31

C2 Blueberry:
Positive Calibration: 9.15
Negative Calibration: 11.13

K1 Burn:
[Need to track down yet, after 2008 June visit]
K2 Met:
[Need to track down yet, after 2008 June visit]
K3 Mauze Gulch: Q99012
Positive Calibration: 8.97
Negative Calibration: 10.90

Troubleshooting

2008-06-20T23:42:46Z

137.229.51.127:

Problem: precip bucket not registering tips
Testing:
# look for animal chews on cable
# do a continuity test. Put multimeter leads on pulse channel and ground and when the tipper is in the halfway position there should be a tone from the meter if you're getting good tips from the bucket. If no tips, try moving the precip bucket to a new pulse port. If unable (due to wind speed in there or something) try moving the leads. C7/C8 & 5V are the same as P1/P2 & G.

Problem: AT/RH not working
# unplug and replug the head.
# wire control wire (orange wire) into 5V. This will leave the sensor in the 'ON' position. Then measure the millivolt output at the SE channel (and AG). I

Problem: All sensors giving haywire readings.
One thing this might be is if you have a sensor that goes bad and it takes 12volts to power it could be damaged, which can sometimes cause the 12 volts to bleed through the system. If 12volts gets to the SE channel then you will get over ranging errors and oddities through other sensors. To check, remove one sensor and make a measurement. Then replace nad move to the next sensor. Eventually things will look good if you remove the busted one. This doesn't happen often but it is a real doozy to trouble-shoot.

Problem: Not getting through with radio communication
# check cabling (coax)
# check that radio is turned on at the control port (with volt meter in addition to looking at flags & control port state)
# When radio is on check the lights on it (should be red-off-blinking red (left to right) unless the radio is in active use).
# check that the antenna hasn't vibrated loose.

Problem: Not getting good readings from stuff on the multiplexer
# sometimes the multiplexer needs a P22 pause statement added to the program instructions. They're supposed to be able to switch super quickly but sometimes they can't keep up with the measurement speed so you end up measuring the wrong channels. A P22 excite with delay with the excitation voltage set to 0mV is the common way to address this.

General Site Checklist

2008-06-20T23:40:03Z

137.229.51.127:

Before going:
# look over data for anything needing attention (like from animal damage potentially)
# make a list of things to do at the station
# bring tools, hose clamp or two, cable ties

On approach to a station:
# asses for animal damage

At station:
# download data
# look at numeric input locations on site to see that things make sense
# pound in with hand maul the guy wire deals if loose (easier later summer than spring)
# address animal damage / known before hand sensor repair work
# check that omni-directional antenna hasn't vibrated loose (it happens especially at K1/K2)
# level the radiometer tower at each summer visit (and then the up looking radiometers)
# set Flag 1 high if a radio is present upon leaving (except in fall)
# last off: double-check that the data logger is connected to the radio (blue or sometimes gray cable)
# take a picture or two in the final state (more good practice than anything else)
# replace dessicant in radiometers at least annually

Seward Peninsula Sites

137.229.51.127:

==== Trip Itineraries====
* [[2007 September Nome Trip]]
* [[2008 June Nome Trip]]
* [[ General Site Checklist]]

====Sites Background====
As carry over from the ATLAS and HARC projects WERC maintains a network of telemetered data stations on the Seward Peninsula. Archived data is currently found on the [http://www.uaf.edu/water/project/atlas/atlas.html UAF WERC site]

Principal Data site, Council Area:
[[C1 Grid]] (near [http://www.udel.edu/Geography/calm/data/data-links.html CALM site U27]), active
[[C2 Blueberry]], active
C3 Guy Rowe, inactive

Principal Data site, Kougarok Area:
[[K1 Burn]] site, active
[[K2 Met]], active
[[K3 Mauze]] Gulch (near [http://www.udel.edu/Geography/calm/data/data-links.html CALM site U28]), active

We use radio telemetry to communicate with our stations out on the peninsula. So, there are several radio repeaters in that list, too. They are:
[[Anvil]] Mountain (near Nome)
[[Skookum]] Pass (near Council)
[[Kigluaiks]] (in Kigluaik Mountains across the valley to the south of Kougarok)

In addition there are several other sites:
[[Snake]] River (outside Nome on Nome-Teller Highway)
[[Kuzitrin]] River (60+ miles up the Kougarok Road from Nome)
[[Niagara]] Creek (~1 mile from K2 Met)

See most of them on a map here:
[http://www.uaf.edu/water/projects/atlas/atlas.html Site Map]

For reference, Nome is above the 'i' in Council. Also mentioned on that page are some sites in Ivotuk. Don't worry about them. They are no longer active.

====Project Background====
Originally there were three Council sites, C1, C2, and C3. Each was selected to be in a different type of landscape but C3 kept getting attacked by bears so we eventually removed it. C1 is called C1-Grid because it is located in the valley bottom near Council along the perimeter of a CALM 1 km x 1 km active layer grid. So, the meteorological station was set up to complement the field data collected on the CALM grid. In terms of importance to the original project it was a secondary station so the data elements collected there are basically: Air Temperature / Relative Humidity (1m & 3m), Wind Speed (1m & 3m) & Wind Direction (3m), Net Radiation (in summer), precipitation (in summer), snow depth, soil moisture (vertically profiled), and soil temperature (vertically profiled). The station is also a shorter 3 meter tower.

===Council Sites===
The blueberry site is located on Blueberry Hill to the SW of Council. It is the primary site for the Council area so has more sensors and the tower is a 10 meter high setup. In addition to the sensors mentioned for C1 there is also up facing shortwave & longwave radiation, and down facing shortwave & longwave radiation sensors. Wind speed & AT/RH (as a single sensor) are also measured at more heights than at C1 (1m, 3m & 10m). In 2007 I made some changes to the station. In the past longwave radiation was measured using a battery. However, it was a lead-mercury battery, which is considered hazardous and has been discontinued so I re-did the wiring. This will be reflected in the data as a couple extra data columns that appear last year. Blueberry is across the Niukluk river (I think that's the river, not 100%) and is sometimes unreachable in fall. So, we weren't able to get across the river to remove the net radiometer in Fall 2007. Data for it shouldn't be trusted much past October 1st though because once the snow falls or frost accumulates on the domes that protect the radiation sensor.

On a similar note, the precipitation gages are out year-round but we only record summer rainfall. So, you should mark with '7777' the winter time of year. For measured precipitation I don't generally count it until the air temperature is consistently above freezing. It's kind of subjective on the shoulder seasons figuring out what is snow vs what is rainfall and if you don't feel comfortable with that, I'm happy to look over the data and define select which points to include and which to exclude. It may sound like we're doing something funky but we aren't. The tipping bucket rain gage is only designed to measure liquid precipitation. So, when snow accumulates in the bucket no measurements are recorded until the bucket temperature gets above freezing to melt the snow in the bucket. Since those gages are just used in the summer then we exclude all solid precip that may melt in and be counted at the data logger.

===Kougarok Sites===
K1-burn is another secondary site. It is located on an area burned by an old tundra fire up on a low sloping bench above the Kougarok river. The vegetation in this area is dry tussock and grasses. Much of the organic soil layer burnt off in the fire so recovery has been slow. This site gets visited fairly frequently by animals so you'll see most of the soil moisture sensors have had their cables eaten, as has also happened to the soil temperature sensors. This site is quite similar to C1 that I talked about earlier in terms of sensor setup. In the fall of 2007 we added a snow depth sensor to the site so that will be a new thing. I'm not sure about its reporting though.

K2-met is the 10 meter tower for the Kougarok area. It is located on very wet tundra 300 meters or so up slope from the Kougarok river, so down in the valley. It is a full site similar to C2 although it also has a snow sensor installed. A broken, older sensor was replaced with a newer one in fall 2007.

K3 mauze is located at the perimeter of the Kougarok area CALM grid. It is another 3 meter tower. This site has been hammered by the bears in recent years so some sensors are in and out in terms of their quality.

===Discussion of the Station Data===
So, that's a short bit of background on the stations. The data on the CD I gave you is predominantly archived data or data that has been through some level of processing. You can find the up to the day data here:
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-blueberry
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-c1-grid
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-k-burn
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-k-met
http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-kmauze

Those are all quite large at this point text files. Let me know if you find any gaps in the data. Sometimes there is trouble with the back end connection between the UAF webserver and the computer that retrieves this data over the radio network from Nome.

So, when you look at the data there it will probably look like a bunch of not real helpful numbers. Plus you'll see an Array ID at the start of the line which seems to alternate each hour. That is because the meteorological data arrays are mixed together withe subsurface data arrays. It's kind of a by product of the data logger we use. The design for them was done in the early 90s or late 80s so the electronic data storage architecture is robust but perhaps a bit primitive compared to the computers of today. So, to split out all the data I should have included on that cd a directory called 'batch' or 'bin'. If you look in there you should see some .bat files which are dos batch files. I don't know if you're using linux or windows, if you're using linux then pop open .bat file and you'll see 'grep .........' you should be able to change the directory paths there (I can help if you have questions about this) but these little batch files basically read through the data above (e.g. atlas-blueberry) and pull out all the met data arrays and then all the soil data array lines and dump them into different files. So, when you mention seeing different data files in the CD I gave you, the data is in various steps of processing. Oh, also, if you are using a windows computer (as I am for the data processing) then you should have cygwin installed. It's a program that gives you many of the free utilities that come with linux/unix/debian (most helpfully for us today, grep). You can download it here if you need:
http://www.cygwin.com

So, if you're using windows, just modify the batch files. I like to use this program:
[http://www.context.cx Context]
for viewing text files. I find it much more useful than notepad, but if you have a favorite text editing program, feel free to use it. Anyway, if you're using windows you'll need to modify the batch file to grep out the 2007 data I think. The general format for the grep command is:
grep [text string to search for] [input data file] > or >> [output data file]
c:\cygwin\bin\grep 228,3018,2007 "c:\data\atlas\c1-grid\atlas-c1-grid.txt" > "c:\data\atlas\c1-grid\c1-grid_228-2007-soil.csv"
You'll see both '>' and '>>' in the batch files. '>' means put all the data line matches into the output file and create a new file each time. '>>' means put all the data line matches into the output file and append them to the end of the file if it already exists.

So, you'll need to change the paths (e.g. 'c:\data\'), to whatever you're using. I like
c:\data\project\station_name from windows or /home/bob/data/project/station_name from linux but totally your call on how you organize. From linux the line above would like more like this:
grep 228,3018,2007 "/home/bob/data/atlas/c1-grid/atlas-c1-grid.txt" > "/home/bob/data/atlas/c1-grid/c1-grid_228-2007-soil.csv"

So, when you see stuff like this:
CD/atlas/C1-grid/c1-grid_123-2006-met.csv
CD/atlas/C1-grid/c1-grid_123-2007-met.csv
CD/atlas/C1-grid/c1-grid_228-2004-soil.csv
etc. etc.
That is output from the grep program. the 123/228 references the array ID. So, that file contains met data from 2007 from this file:
[http://www.uaf.edu/water/projects/near-real-time/rawdatafiles/atlas-c1-grid C1 Data File]
Here's a sample line:
123,3018,2005,1,100,-0.47,-0.176,97.7,96.1,3.639,162.7,4.414,92.7,0,-2.046,12.35

I see for some flies the '123' has been replaced by the regular date & time. But that's probably the only change in the file. I would have done that if I was just checking things out.

So, moving forwards a bit, my rough method for processing the data is this:
# download data off website
# use GREP to separate out by data line type and year using the batch file for dos.. or if you use linux then you can actually edit the .bat files to be the correct path (like I mentioned above) and then from the command line type this: chmod u+x c1-grid.bat this will allow you to just type './c1-grid.bat' just as I have been doing but you'll do it from linux rather than windows.
# open in excel or use a program I wrote to process the data (more on this below)
# view the data with a data visualization program I used Origin but Excel is semi okay (origin is nice because you can quickly change the time scales) or if you have another program you really like like matlab that's fine, too.
# delete bad data that is apparent through using the visualization program (replace with '6999')
# have someone else do a final check (like me probably)
# post data to the internet

'process the data' is pretty nebulous. I have a program I wrote which converts thermistor resistances (soil temperature data) from resistance to temperature and then formats the data as it should look on the web. That's the main reason you see so many similarly named files. Some are from step 1, some are from step 2 etc. So, that is probably a bit confusing. But for you, probably using a spreadsheet program like excel or whatever you're most comfortable with is better. You can find header information for what is in each column of the data file. The other main bit of 'processing' that happens is to correct the net radiation data for wind. I can dig that equation up for you if you can't find it in those spreadsheets.
So, also along the process the data lines, some things you'll want to look out for:
# missing lines of data... make a note and check with me if you find any
# repeated lines of data... more likely to find due to the rsyncing process (the way the uaf website talks to the server downloading data from the radio network).
There are a couple ways of converting julian dates into regular. You could use these programs I've written for visual basic:
http://werc.engr.uaf.edu/mediawiki/index.php/Excel_Macros
or, another way is this:
a) type into a cell '12/31/06'
b) change the format of the cell to number.
c) if your data is in the format column 1 is the date you'd like, column 2 is the year, column 3 is the day, column 4 is the hour then in column 1 you can print (using data for 2007) '= 39082 + b1 + c1/2400' then format this column as a date & time and you'll be in business. Do some simple boolean stuff to check for gaps of data or, just create another column that has as the first cell '1/1/07 1:00' then the second row in the column '=a1 + 1/24' then look to see if the calculated date (mentioned first) ever varies from the second method. If it doesn't you're golden. If they do vary then you can track down where the problem is. In general, if there is multiple lines of the same data (or so it looks like) I will delete the first instance and keep the last. The reason for this is related to the radio telemetry. Some of the connections are quite weak so we don't always get the data on an hourly basis. Sometimes we'll get half the line so we'll need to get things resent later (with regard to the radio network and data retrieval from the data loggers).

I guess another note on the array IDs. The met data and the radiation data are contained in the same array ID line. The soil temperature and soil moisture data (most of which has broken sensors) is in a separate array ID. That is the 123, 127 etc. that you wonder about below.

Well, I've written a book, maybe I will post this to our wiki and we can go back and forth on there, too. Totally let me know if you have any questions. I'll be in town through Friday (just learned) so I should be able to help more in the short term than the medium term. thanks

============== Part 2 ===================
Here's a bit about the radiation. I will get you more calibration values once we're back from the June trip the week of 6/16.

So, in the data files you've looked at off the internet is the output voltage in millivolts as recorded by the data logger. To get from milliVolt output from the data logger to Net Radiation in Watts / m^2 you'll need to do a couple things:
1) correct for wind speed.
2) apply the sensor specific calibration factor (positive or negative depending on sensor output)

Via this manual (pdf page 5 document page 3):
Net Radiometers -- REBS Q-7.1 (Radiation Energy Balance Systems)
http://www.campbellsci.com/documents/manuals/q-7-1.pdf

Are these wind speed correction equations (where wind speed in in meters per second as we have at our stations):

Positive Wind Speed Correction Factor:
Wind_CF_Pos = 1 + (0.066 * 0.2 * 1m_Wind_Speed) / (0.066 + (0.2 * 1m_Wind_Speed) )

Negative Wind Speed Correction Factor:
Wind_CF_Neg = (0.00174 * 1m_Wind_Speed) + 0.99755

So, if Net Radiation (in mVolts as recorded by the data logger) is positive use this equation:
Corrected_Net_Rad = Wind_CF_Pos * Uncor_Net_Rad * Pos_Calib

If Net Radiation (in mVolts as recorded by the data logger) is negative use this equation:
Corrected_Net_Rad = Wind_CF_Neg * Uncor_Net_Rad * Neg_Calib

Here's the equation for C2 as it looks for me in Excel:
=IF(ABS([NetRadiometer Cell])<> 6999,IF(L4087>0,9.15*[Net Radiometer Cell]*(1+(0.066*0.2*[1 meter Wind Speed])/(0.066+0.2*[1 meter Wind Speed])),11.13*L4087*(0.00174*[1 meter Wind Speed]+0.99755)),7777)

So, given all that you need one more thing, the calibration values for positive and negative calibrations. Here's a first batch and I'll get you some more after we come back from out trip in a couple weeks.
C1 Grid:
Positive Calibration: 9.18
Negative Calibration: 11.31

C2 Blueberry:
Positive Calibration: 9.15
Negative Calibration: 11.13

K1 Burn:
[Need to track down yet, after 2008 June visit]
K2 Met:
[Need to track down yet, after 2008 June visit]
K3 Mauze Gulch: Q99012
Positive Calibration: 8.97
Negative Calibration: 10.90
