Data QA

Extra Notes

  • For data grouping routine there is something off with the pit temperatures... more specifically one set is reported as 'Avg' so I must not have correct headers.
  • Just a historical note that the Top snow stand on the lump had been bent over sometime prior to Ken H visit in fall 2020... I sorta think this happened in the winter of 2019-2020 but need to circle back to that to confirm.
    • Ken visit: 10/31/20 @ 19:40 is final data in Snow.dat.

Main

NGEE

Latest

  • Met Data QA'd through last visit (9/2018)
  • Radiation Data QA'd through last visit (9/2018)
  • Partway through processing soil.

Met 2017

  • HMP155 August 2017
    • failure looks legit... not a data gap.
  • HMP155 Cuts out on 10/25 8:00
    • replaced AT portion with new AT thermistor.
    • DP & RH left NAN
  • HMP155 replaced on March 2018 visit
  • Rain corrected through most recent download.
  • Wind Speed / Direction
    • Propeller replaced 6/28/2017
    • No Rime fall 2017

Met 2018

  • Wind
    • all rime conditions corrected for through 3/2018 in QC spreadsheet.
  • Rain NAN through snowmelt
  • Radiometer leveled and desiccant replaced 6/12/2018
  • Radiometer leveled again 9/24/2018
  • Tipping bucket leveled 6/12/2018 & 9/24/2018
  • AT/RH corrected through 3/30/2018 20:00 after sensor destroyed over winter season.

Radiation 2017

  • There is a gap 10/2/2017 0:00 to 10/2/2017 22:00
    • I think this is when we removed the sensor from the field to change the desiccant.
      • as in, the screws were stripped and so we drilled and retapped back in town.

Radiation 2018

  • All good through March visit.
    • There is a weird thing in 2018 where the lower SW has values higher than the upper SW. I assume this is due to snow/ frost up top. Perhaps related to how close the snow surface is to the sensor this year resulting in a lower wind speed later in the winter.

Soil 2017

  • 2017 heat flux plates prior to fall were being measured on wrong channel.
  • 2017-03-12 02:00:00 Upper heat flux plate has a value that isn't ever flipped by the qc program.
  • 2017-03-12 02:00:00 Lower heat flux plate has a value that isn't ever flipped by the qc program.
  • Easy Perl one liners to accomplish this:
perl -pi -e 's/"2017-03-12 02:00:00",149.2/"2017-03-12 02:00:00",6999.00/g;' $TT_SOIL_DIR/outputs/SoilPit_HeatFlux_Lower.csv
perl -pi -e 's/"2017-03-12 02:00:00",140.8/"2017-03-12 02:00:00",6999.00/g;' $TT_SOIL_DIR/outputs/SoilPit_HeatFlux_Upper.csv
  • 2017 Soil pit soil moisture -- all corrected
  • 2017 Soil heat flux plates also all corrected
  • with Vlad determined only good VATP are 2/5/25/50/60/100
  • Soil Temperature: VATP
    • I think I have everything corrected though I don't entirely believe the 100cm probe.
  • 8/16/2017 from Lily's field book page 50:
    • VATP was heaved 9.5cm above standing water table. I pushed it back down

Soil 2018

  • 2018 soil pit soil moisture -- all corrected through most recent visit (3/2018)

Soil 2021

  • I've decided the top site experiences high heat fluxes in spring / summer and it seems likely the output is overranging the measurement thresholds set in the program.

Snow

Snow 2018

  • Snow temperature profile
    • Weird shift (looks like mux wonky 1/22 to 1/28/2018)
