Post Trip Notes
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.
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 : 2021-02-11
Barometric Pressure
- All Good
- NAN data is due to low battery voltage
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.
