General

  • Look over bash script... need to make sure that QA corrections take place after stage is corrected to match rebar values...
    • a second QA I think.
  • I'm looking at the 2017 April 27 & 28 discharge measurement times and the corrected data looks great but the raw data looks like it has the shift applied too early. Perhaps that is unavoidable? I'll think on it. but currently not fixed 11/7/2018
  • Basin Size is 1.24 km^2 or 1,243,875 m^2* I think we need to double-check this value using the high resolution DSM from LANL. 2/14/2019

Latest

  • Officially processed through 3/2019
    • there are some early winter 2017 peaks I think should be considered.

Stage 2016

8/13/2016 3:00	PTs offset
9/14/2016 22:00	PT1 Position Reset & PT2 Removed
  • 2016 Offsets for corrected PT 1 Stage:
"2016-08-13 03:00:00",-0.61
"2016-08-15 02:30:00",-0.49
"2016-09-14 22:00:00",-1.83
  • Hourly Processing deletions:
    • 2016-09-15 17:00 to 2016-12-31 23:00 :
      • In fall there is a diurnal component to stage that is driven by air temperature I think due to exposed pressure transducer cable after the leaves fall.
      • Probably good data returns for a bit later in fall but it is hard to say just when the channel shape changes due to ice. So, I lean to remove all data until 2017 April visit

Stage 2017

4/1/2017 3:00	Station Turned back on, PT2 in place further downstream
10/1/2017 20:00	PT2 Removed
4/28/2017 1:50 shift in pt2? then
  • Offset for 4/1/2017+
"2017-04-01 01:30:00",-3.10
  • Hourly processing deletions:
    • 2017-01-01 0:00 to 2017-04-01 2:00
      • Winter / station battery dead
    • 2017-10-24 21:00 to 2018-05-14 20:00
      • Winter / hard to say when channel shape changes.
      • I set this date due to the creek being in recession for winter and the water temperature signal which is a full on guess. For reference, I NaN out the summer precip on 10/15. So I'm not 100% confident this is the right time to the hour but probably it's okay?
      • Ending date in May 2018 was selected as first day with a diurnal signal in water temperature (i.e. snow melt has melted the snow in the channel) and also, the first Q peak in May to me looks snow influenced. But 5/14 is down from that peak.

Stage 2018

6/15/2018 12:40 AKDT 12cm above rebar 1; 20.5 cm in front of rebar 1
9/24/2018 18:50 AKDT 3cm above rebar 1; 13cm in front of rebar 1
9/26/2018 10:48 AKDT 5cm above rebar 1; 14.5cm in front of rebar 1

From Computer Notes

Need to put into a spreadsheet pressure transducer value / date / manual stage reading.... need to review notes.

Related: discharge measurements
Related: Get manual stage & discharge measurements into UTC time.

Then once that is complete can look at using 
/var/site/uaf_sp/bin/teller_sw.sh
and the step utility function to correct everything to proper heights.
...should think about gedit plug ins too to make it more like xed.

2/8: So.... including precip helps but there is still a period in september / october 2016 that confuses me with the diurnal signal looking more like air temperature driven.  Emily and I sort of think that the heating of the cable might be playing a role here but I haven't looked too hard yet.
