August 2014 Barrow
Revision as of 08:59, 22 August 2014 by 199.165.126.77 (talk)
To Do:
- Change out snow transducers, 8 pieces
- swap back the B site net radiometer
- change out desiccant in the D site radiometer
- level radiometers
- Fix C site Rim Snow Sensor
- D Thermal Conductivity
- Program works fine in Fairbanks
- OKAY... Look at how it is wired in the field. / in pictures. I think there are two pulse port instructions when there should be just one.
To Bring:
- CNR4 Net Radiometers
- One for B (the original)
- retap the D screws and if I can't get that to work then move the alternate radiometer from inventory (B) to D.
Plan:
Code: FDVIBG
Depart Thursday morning @ 7:40am
Return Friday night @ 12:21 AM

At each site

Wrap up notes
- Precip stands seem to be levelest at A & C so might be best to use them.
- most net radiometers were close to level.
- Look into buying more tap & die drill bits & the alternate type that dead end flat like Bill mentioned.
- see about buying more of the SR50A screws that secure the disposable transducer to the main body.
- The C site Net radiometer will need to be tap & drilled on the next trip. I greased all but one screw on this trip but it was stripped on the head.
- should grease all hardware (the main ones like SR50A, net radiometer etc) annually.
