SGP/SWATS/E20 - Sensor failures
DataStreams:sgpswatsE20.b1
Description:
Following a period of missing values (-9999) from 08/05/05-08/17/05, sensors at several 
depths failed.

Temperature rise values from the 60cm West and 85cm East profile sensors were very noisy 
after 08/17/05. These data, including matric potential and water content, were incorrect.

Temperature rise values from the 85cm West and 125cm East profile sensors are reported as 
0 after 08/17/05. Matric potential and water content data for these sensor were also 
incorrect.  Soil temperatures for these depths were unaffected.

Temperature rise and soil temperature measurements for the 60cm East and 125cm West 
profile sensors were reported as 0 or -9999 after 08/17/05. Matric potential and water content 
data for these sensors were also incorrect.
