Post Trip Notes

October 2021

  • In September 2021 we added a third battery and a second site to get a second snow / precip / air temperature
  • Reviewing the data in mid October... I think the geonor is killing the battery even in the summer time. I left it connected when we left September and it seems likely to me the site will fail sooner this winter. Battery voltage had dropped to 12.2 in September after a summer of clouds.


October 2020

  • All AT/RH Broken
  • Think about putting out a second datalogger co-located since the wiring is so set... or not... I should look into it...
    • ... in order to have a nonborked reference air temperature and reference tipping bucket.
  • Reviewing pictures 10/2021 while trying to figure out when the radiometer went out of level I see it was sometime before the October 2020 data download.

June 2019

  • Tripod Mast Bent
  • CNR4 difficult to level
  • Could use a some help keeping lower anemometer from moving. Like maybe a couple pieces of unistrut to keep arm from wobbling
  • Need to replace lower AT/RH as it seems completely broken.
    • Rotronic HygroClip2 HC2A
    • Should look to see if they sell a better top cap for it more resistant to moisture
  • Need to get some SW12V adapter to turn AT/RH on/off and look at program / wiring for other things that could be turned off.
  • Left 2 guy wire anchors and 100' of guy wire at UAF Storage. Could bring out more anchors or unistrut / nails or something. Maybe pound unistrut into ground and then pin in place?
  • I thought Geonor and Solar Panel would require guying but both survived the winter while tripod mast didn't.
  • I think snow sensor maybe failed over the winter, too.
  • I was thinking a heavier gauge cable for solar panel might be appropriate, too.
