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.
Suggestions: 
Measurements:sgpswatsE12.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Sensor Temperature Rise, East Profile(trise_E)
