==== Problem Sensors (as of June 2008) ====
* Meteorological Sensors look great
* Radiation Sensors look great
* Judd snow sensor looks good, too:<br>
[[Image:K2-snow.gif|400px]]<br>
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.
