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:
