Problem Sensors (as of June 2008)

  • Meteorological Sensors look great
  • Radiation Sensors look great
  • Judd snow sensor looks good, too:

Although I wonder what the deal is with the drift (hysteresis) and what might have caused that midwinter spike.

  • Look to see if 30 cm bgs Soil Moisture has become disconnected (loose wire)
  • Look at YSI thermistors again

Site To Do List

  • Look to see if 30 cm bgs Soil Moisture has become disconnected (loose wire)
  • Look at YSI thermistors again: buried at 70 cm bgs YSI model 44034
  • Replace 1m, 3m, 10m AT/RH sensors in 2009... 1m RH infrequently over-ranges (3/2009 note)
  • Bring all all radiometers back out in 2009. Bring new mounting hardware, too.
