Met

Met 2016

  • All fixed prior to start of this page... I'll go back and add notes as time allows.
  • But, station put up in early April 2016 as a temporary setup on a
  • Summer Precip Ends: 11/04/2016 02:00
  • Need to revisit data grouper to address the pandas change with respect to NAN and averaging. 10/12/2018 (for AT/RH/DP in 2016 April)

Met 2017

  • all good / corrected... same as above, I will add notes later.
  • Last Winter Season Precip: 04/21/2017 18:00
  • Start of Winter Season for Precip: 10/15/2017 13:00

Met 2018

Data Record really ends for 2018 on last visit. Another CF card failure.

  • Barometric Pressure good through 6/2018 visit
  • Wind Speed & Direction good through 6/2018 visit
  • Air Temperature / Dewpoint / Relative Humidity good through 6/2018 visit
  • Rain Gage destroyed by moose 12/25/2017.
    • Bucket fixed 6/13/2018 around 21:00 - 22:00 (tips in data were test tips with new bucket).
    • QA file reflects this.

Met 2019

(Year really does start on 3/31/19 21:00ish. Another CF card failure. On the snow survey trip I changed how things are saved and no gaps since I believe.

  • Barometric Pressure good
  • Wind Speed and Direction Good.
  • Rain
    • Spring/summer season begins once moose damage is repaired. First data point: 6/11/2019 1:00 UTC
    • Moose damage again on 7/16/2019 0:00
    • Fixed and test tips 8/20/19 1:00
    • Fall season runs until 10/16/2019 4:00
  • AT/RH/DP all good.

Met 2020

  • Bit of Rime Ice on the anemometer March 2020
    • & November
  • Rain
    • Start of season: 4/23/20 22:00
      • I'm starting Spring way early for 2020 because it's clear from QA'd data that snow melts out of bucket by the 20th of April and there is no more tipping until 5/12.
    • End of season: 10/13/20 4:00
      • This is the safe ending date. It's quite possible that the precipitation 10/15 to 10/24 could be included but at least the 10/15 I suspect is snow that fell 10/13 or 10/14? So timing of the tips is off compared to when it fell. I waffle I guess but just going to delete after making this note.
  • AT/RH/DP all good
  • Barometric Pressure all good

Met 2021 (through 9/19)

  • I noted this on the next visit page but there is a data gap corresponding (roughly) to files with suffix 108 to 113 (all data tables).
    • Roughly: 5/10/21 0:00 to 6/7/21 00:00
  • Barometric Pressure: all good (through final station visit 9/19/21)
  • AT/RH/DP: all good (through final station visit 9/19/21)
  • Wind:
    • Rime Ice 1/23/21 19:00 through 1/28/21 5:00
    • One loose end: I need to double-check WD. Moose hit site twice this year definitely look at radiation....
    • Possibly: ??6/16/21 17:00 to 6/23/21 22:00?? look at data
      • Looking at data wind it is basically impossible to tell. So I guess if so, it was a minimal error. I made some more notes about this in the radiation 2021 section.
    • For sure: 7/29/21 2:00 to 9/10/21 21:00
    • From photos of analog compass, anemometer E-W line was at 290 but should have been @ 270. So, made a special WD corrections QA file just for this.
$ROOT_DIR_TB_MET/qc/teller_bottom_fix_WD_only.xls
  • Summer Precip
    • Season Start: 4/21/21 21:00 (for real)... best I can declare anyway
    • After season starts there is the file I/O error data gap and then prior to station visit legit precip in June.
    • Reviewing the station visit in Fall 2020 pictures I can see precip bucket was still in place.
    • So I think I'm going to just NAN data after the last rainfall in June until my station visit.
    • 6/14 / 6/15 rain event matches with top data so I think 6/15/21 9:00 to 6/23/21 23:00 delete.
      • From Shortwave radiation data I think around 6/16/21 20:00. Spike in reflected data.

Radiation

Radiation 2016

  • all good / corrected

Radiation 2017

  • all good / corrected

Radiation 2018

  • SW & LW & Skin Temp look good through 6/2018 visit.

Radiation 2019

  • all good / corrected

Radiation 2020

  • all good / corrected

Radiation 2021 (through September visit)

  • Moose damage: 6/16/21 17:00 to 6/23/21 22:00
    • I don't think this damage affected the anemometer direction much... correct. Just looked at the video again. solar panel is facing south and tripod SR50A looks to be centered over the right patch of ground.
  • Moose damage: 7/29/21 2:00 to 9/10/21 21:00
    • I think there is a bit more between 9/10 and 9/21, too but this is just a note for later. We better secured the cross arm on second visit to the site and it was disturbed again on the third visit the 21st maybe? I'll have to look.
  • Working on pinning down this last bit of damage. It is hard to say but either 9/18/21 23:00 or maybe 9/19/21 17:00? Judging by albedo and reflected shortwave radiation. I think another thing I could look at would be IS2 snow station data. We were at that site when two moose tore by.

Soil

  • I need to dig into the fieldbook notes to see if the VATP jacked at all in 2017.
  • The view from 2021: I think the VATP data is probably just errant start to finish. Soil pit data has utility.

Soil 2016

Soil 2017

  • Heat Flux plates nonworking until 10/2017

Soil 2018

  • 2018 heat flux plates look decent.
    • it could be that top & bottom are flipped and also that what should be the top is actually flipped in sign?...need to compare to top.
      • 2021-05 Update: Yes I think this is true after putting all flux plates on same plot.
      • given that, need to follow up somehow and check the multiplier, too to make sure they're correct. Like, easy to change the data processing to flip the two but need to see if I need to check on if the calibration coefficient is being applied to the right one.
      • on top of all that, the wires are backwards or the plate is upside down for the upper plate.
  • VATP
    • Blip during station visit at 6/13/2018 21:00

Snow

Tripod Snow 2016-2017

Snow 2017-2018

Station History / Site Downloads / visits:

September 24 & 26 2018

  • B Busey / Bolton / CAS
  • memory problem on logger 9/24 but due to food poisoning just downloaded data.
  • returned 9/26 and upgraded the OS to latest
  • resent program & readdressed.
  • I don't yet know the problem here? Error in CF card perhaps? In 2019 I will replace the CF card with another.

June 13 & 15 2018

  • Station Maintenance @

  • fixed animal damage
    • snow sensor knocked over 12/25/2017
    • tipping bucket removed probably around then, too.
  • fixed program bug

April 10 2016

  • Temporary station built above flood plain. Station put in at end of first snow survey trip of Teller.
  • At that point this was labeled the blue site (the blue electrical tape IDed this site in the logistics phase).

    • AT/RH
    • 4 component Radiation
    • Surface water

April 21 - May 5 1 2016

  • Station visited nearly daily during ablation trip

July 2016

  • LC visited and downloaded data.
  • Temporary station had fallen over (knocked by an animal).

August 12 - 22 2016

  • Wind Speed / Direction added
  • W
