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
    • Data Points From April Trip:
      • Heater Resistance #1 -- 68.2 ohms
      • Heater Resistance #2 -- 70.2 ohms
      • Heater Resistance #3 -- 70.4 ohms
      • Heater Resistance #4 -- 70.7 ohms
      • Heater Resistance #5 -- 69.1 ohms
      • Heater Resistance #6 -- 70.3 ohms
      • Thermal conductivity thermistor resistance #1 -- 57.6 kohms
      • Thermal conductivity thermistor resistance #2 -- 57.8 kohms
      • Thermal conductivity thermistor resistance #3 -- 58.2 kohms
      • Thermal conductivity thermistor resistance #4 -- 57.5 kohms
      • Thermal conductivity thermistor resistance #5 -- 58.0 kohms
      • Thermal conductivity thermistor resistance #6 -- 58.4 kohms
  • 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 but I don't know for sure until I review the photos / see it in person.
  • Basically there are two

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 to D.


Plan: Code: FDVIBG Depart Thursday morning @ 7:40am Return Friday night @ 12:21 AM

Thursday

  • grab coke in Fairbanks airport
  • Arrive at NARL around 11am
  • get keys and dress for day in field
    • wind breaker
    • backpack ready to go
    • lunch for the day
    • Water bottle
    • actionpacker with:
      • 8 snow sensors
      • toolbag
      • net radiometer for B
      • drill for tapping D radiometer if needed
      • 6/32 screw for D
      • also bringing a 4/32 screw & tap for backup.


Tonight:

  • pack backpack
    • raincoat
  • overnight stuff
