SGP/SWATS/E16 - Incorrect soil moisture
DataStreams:sgpswatsE16.b1
Description:
Sensors for all levels in both profiles were reporting values of temperature rise at or 
near 0 C.  The incorrect values of temperature rise result in incorrect soil moisture data.
Measurements:sgpswatsE16.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Sensor Temperature Rise, West Profile(trise_W)

SGP/SWATS/E16 - Sensor failure, 125cm E
DataStreams:sgpswatsE16.b1
Description:
Temperature rise values from the 125 cm E sensor began to intermittently drop out to 
values near 0 C starting at 4:00 GMT on 12/14 before permanently reporting values near 0 C at 
20:00 GMT on 12/15.  The incorrect values of temperature rise result in incorrect matric 
potential and water content data for these sensors.

Soil temperature for this sensor is not affected.  

Sensor resumed working 20090425.
