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

• 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.

Radiation

Radiation 2016

• all good / corrected

Radiation 2017

• all good / corrected

Radiation 2018

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

Soil

• I need to dig into the fieldbook notes to see if the VATP jacked at all in 2017.

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.
• VATP
  • Blip during station visit at 6/13/2018 21:00

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 @
  • 6/13/2018 20:00 UTC
  • 6/15/2018 20:00 UTC
• B Busey & N Wales
• 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).
• Site established around 4/10/2016
  • 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

• LC & B Busey improve upon site making Teller Bottom site and splitting off the Teller Surface Water Station.
• Wind Speed / Direction added
• W
