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 for 6 hr gap of data 2007 day 162 600 to 1200 (probably an rsync gap)
• Another data gap 2007 day 255 600 to day 258 1900 (possibly a combo data gap: rsync plus program change)
• 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
• Bring all all radiometers back out in 2009. Bring new mounting hardware, too.
