SGP/SWATS/E1 - Reprocess: Wrong Calibration

Two sensor connections were switched. The East 125-cm sensor was plugged into the East 
85-cm sensor's connection, and vice versa. Technicians corrected the problem on 1440 GMT, 
08/02/00, and returned the instrument to service 10 minutes later at 1450 GMT. As the 
datalogger was confusing the 2 sensors, incorrect calibrations were applied.

The correct calibrations can be applied to the raw data to obtain the correct temperature 
rises, soil moisture, etc. However, this is a rather large amount of work to apply toward 
just 1 measurement profile.  This has been identified as a medium priority reprocessing 
task.

SGP/SWATS/E1 - Incorrect Soil Moisture Data

The temperature rise readings from the 5-cm depth on the east profile (trise_E) are 
incorrect. This also causes the matric potential (soilwatpot_E) and water content (watcont_E) 
data for the 5-cm depth to be incorrect.

SGP/SWATS/E1 - Questionable Soil Moisture Data

Between the 06GMT and 07GMT measurements on January 14th, it appears that some sort of 
non-atmospheric moisture source affected the 4 shallowest sensors (5-cm West & East, 15-cm 
West & East). No precipitation was recorded at the site, but data indicate a sharp 
increase in soil moisture that caused suspicious behavior that gradually lessened through 
January 23rd. Animal intrusion, but more probably adolescent mischief, is suspected.
