SGP/SWATS/E1 - Sensor failure, 25cm E
DataStreams:sgpswatsE1.b1
Description:
The soil sensor at the 25-cm depth on the East profile began reporting missing or 
incorrect values for all soil moisture measurements (trise, tsoil, soilwatpot, watcont).

Instrument removed from service 20091014.
Measurements:sgpswatsE1.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, East Profile(soilwatpot_E)

DataStreams:sgpswatsE10.b1
Description:
All variables from the 15cm West sensor are reported as missing. The sensor has failed.
Measurements:sgpswatsE10.b1:
  • Sensor Temperature Rise, West Profile(trise_W)
  • Volumetric Water Content, West Profile(watcont_W)
  • Soil Temperature, West Profile(tsoil_W)

Subject:
SGP/SWATS/E10 - Sensor failure, 15cm E
DataStreams:sgpswatsE10.b1
Description:
The 15cm E sensor failed at 7:00 GMT on 06/02/2002. Values of temperature rise from this 
sensor often do not fail automated QC tests, but inspection of the time series reveals 
that the values are incorrect. Since 2002, this sensor has alternated between providing 
temperature rise values near 0 C, equal to -9999, or other obviously incorrect values. 

Soil temperature data are not affected.
Measurements:sgpswatsE10.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Sensor Temperature Rise, East Profile(trise_E)

Subject:
SGP/SWATS/E1 - Sensor failure, 85cm E
DataStreams:sgpswatsE1.b1
Description:
Both trise and tsoil for the 85cm E sensor dropped out reporting values of -9999 starting 
on 08/24/2005.  Interestingly, both this sensor and the one at 85 cm W (D040730.1) began 
to report data again June-August 2006.  Both sensors have reported values of -9999 after 
this brief period through the current date.  This problem impacts tsoil_E, trise_E, 
soilwatpot_E, and watcont_E. 

Instrument was removed from service 20091014.
Measurements:sgpswatsE1.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
