NGEE Teller Top Notes

Latest

• Met Data QA'd through last visit (3/2018)
• Radiation Data QA'd through last visit (3/2018)
• 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 March visit.

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

Snow 2018

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