SGP/SWATS/E3 - Incorrect Soil Moisture Data
DataStreams:sgpswatsE3.b1
Description:
The temperature rise readings from all depths on both the east and west profilesare 
incorrect. This also causes the matric potential and water content data to be incorrect.
Measurements:sgpswatsE3.b1:
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)

Subject:
SGP/SWATS/E3 - Sensor failure, 60cm E
DataStreams:sgpswatsE3.b1
Description:
The temperature rise readings from the 60-cm depth on the east profile (trise_E) were 
incorrect.  This problem also causes the matric potential (soilwatpot_E) and water content 
(watcont_E) data for the 60-cm depth to be incorrect.  The sensor began to behave 
erratically at 7:00 GMT on 07/10/2008 before an apparent failure at 10:00 GMT on 08/07/2008.  
Maintenance on 10/29 corrected the problem.

Values of tsoil_E at the 60 cm depth are not impacted by this problem.
Measurements:sgpswatsE3.b1:
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
