Problem Sensors (as of June 2008)

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

400px
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.
