2022 NGEE Utqiagvik September Trip

Trip Notes

Anti corrosion goo saved the day here. No screws stripped on this visit. Everything easy to swap. Definite best case scenario after a three year gap between visits.

• @ Site A
  • Replaced all AT/RH and 014A sensors with new / recalibrated units
    • Lower 014A had bent cups but both should be reading NAN until visit.
  • replaced both snow transducers
  • leveled CNR4 and replaced desiccant
  • leveled tipping bucket
  • site back to 100%.
• @ Site B
  • Replaced all AT/RH and 014A sensors with new / recalibrated units
  • replaced both snow transducers
    • Tripod SR50A not reading. I looked over the wires and the data and I think this must have been an issue in 2019, too as all the wiring looks ok. So I vote internal corrosion or something else.
  • leveled CNR4 and replaced desiccant
• @ Site C
  • Replaced both 014A WS
  • Only replaced upper HMP155. The lower one is still working and and the sensor cable was corroded onto the sensor. I think with a skinny wrench (and here I am thinking probably a metric bike tool would be the hot ticket) they could be disconnected but since it was still working, shoulder shrug emoji, just left it as-is.
  • Tipping bucket still level and so didn't fuss with it.
• @ Site D
  • Replaced the 014A WS
  • Did not replace HMP155 as it is still working.
• @ BEO Control Shed
  • Redeployed the computer
  • it worked right off and data downloads resumed.
  • now using an internal IP address and pushing data to ocotal
  • SSH connection to monitors is broken by monitors firewall so I will need to look into current IP.

Activities

• I listed things working and broken below but I also brought enough instruments to completely replace:
  • All snow transducers

• • All AT/RH
  • All WS
  • All CNR4 desiccant

To Bring

• Radiometer Desiccant
• SR50A transducers
• Anemometers
• Tap & Die set for radiometers
• Anti Corrosion Goo
• Toughbook
• Toolbags
• Computer
