Subject:
SGP/SWATS/E12 - Incorrect soil moisture
DataStreams:sgpswatsE12.b1
Description:
Temperature rise values were way to high (~40 deg C).  Water potential is calculated from 
a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees 
C.  When the temperature rise is too high, the soil moisture data is dubious at best and 
unusable at worst.  Since this "out-of-bounds" t_rise is so high, the soil moisture data 
are practically unusable.

Soil temperature measurements were not affected.
Measurements:sgpswatsE12.b1:
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Volumetric Water Content, West Profile(watcont_W)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)

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)
