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.

Data Notes

Most Recent QA : 2021-10-21

Barometric Pressure

  • Mostly Good
  • NAN data is due to low battery voltage
  • I don't know why but replacing the broken AT/RH and replacing them with working ones bonked this sensor for the summer. I didn't notice till 10/21 but can see from the data that

1.5 meter Air Temperature / Relative Humidity / Vapor Pressure

  • Sensor Fails over 2018-2019 winter due to moisture.
  • 2019-01-03 23:00 UTC

3.0 meter Air Temperature / Relative Humidity / Vapor Pressure

  • NAN data in 2019 Winter is due to low battery voltage
  • Without site visit hard to say why sensor goes dead on 2019-09-19 21:00
    • Loose wire?
    • the timing...

1.5 meter Anemometer

  • NAN data in Winter is due to low battery voltage

3.0 meter Anemometer

  • NAN data in Winter is due to low battery voltage

Precipitation

  • Disconnected in winter to reduce battery load.
  • Need to empty bucket every visit. It looks like there is just too much precip in Nome area for our visiting frequency.

Radiation

  • Albedo
    • Blip at 2018-11-20 3:30 to delete
    • need to limit to 0. to 1.

Soil Pit 1

  • Winter data gaps and NANs due to low battery voltage
  • Sensor 5 dies 2020-05-16 22:00
  • Sensor 3 dies 2020-05-16 22:00
  • Sensor 2 dies 2020-06-01 10:30
  • Sensor 4 dies 2020-06-01 10:30

Soil Pit 2

  • Winter data gaps and NANs due to low battery voltage

Snow

  • Transducer fails in January 2019.
