SGP/SWATS/E4 - Incorrect soil moisture data
DataStreams:sgpswatsE4.b1
Description:
The temperature rise readings on both the east and west profiles are too high.  This also 
causes the matric potential and water content data to be incorrect.

For the first, third and fourth date ranges, measurements are incorrect for all sensor 
locations (each depth on both profiles).

For the second date range, measurements are incorrect for the lowest 8 sensor locations 
(the 60cm, 85cm, 125cm, and 175cm depths on both profiles).
Measurements:sgpswatsE4.b1:
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)

SGP/SWATS/E4 - Sensor failures, 5cm and 15cm W
DataStreams:sgpswatsE4.b1
Description:
The temperature rise readings from the 15-cm depth on the west profile were incorrect from 
20040212:1500 to 20040217:0800. This also caused the matric potential and water content 
data for the 15-cm depth to be incorrect.

The temperature rise readings from the 5-cm depth on the west profile were incorrect from 
20040217:2300 to 20040218:1900. This also caused the matric potential and water content 
data for the 5-cm depth to be incorrect.
Measurements:sgpswatsE4.b1:
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Volumetric Water Content, West Profile(watcont_W)

SGP/SWATS/E4 - Sensor failure, 5cm E
DataStreams:sgpswatsE4.b1
Description:
All variables from the 5cm depth on the east profile are reporting as -9999.  Sensor has 
failed.
Measurements:sgpswatsE4.b1:
  • Soil Temperature, East Profile(tsoil_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)

SGP/SWATS/E15 - Incorrect soil moisture
DataStreams:sgpswatsE15.b1
Description:
At 20:00 GMT on 05/07/08, temperature rise data from ALL sensors on both profiles began 
reporting values of temperature change near 0 C. These incorrect values of temperature rise 
result in incorrect soil moisture data for all sensors. 

Soil temperature data are unaffected.
Measurements:sgpswatsE15.b1:
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Volumetric Water Content, West Profile(watcont_W)
