Subject:
SGP/SWATS/E5 - Sensor failure, 25cm E
DataStreams:sgpswatsE5.b1
Description:
The temperature rise readings from the 25-cm depth on the east profile are incorrect. This 
also causes the matric potential and water content data to be incorrect.
Measurements:sgpswatsE5.b1:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)

SGP/SWATS/E5 - Sensor failure, 35cm E
DataStreams:sgpswatsE5.b1
Description:
The sensor at the 35-cm depth on the east profile reported missing values for a couple of 
weeks.
Measurements:sgpswatsE5.b1:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Temperature, East Profile(tsoil_E)

Subject:
SGP/SWATS/E5 - Incorrect soil moisture data
DataStreams:sgpswatsE5.b1
Description:
The temperature rise values were too high (> 20 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 T_rise is too high, the soil moisture data is dubious at best and unusable 
at worst.

Soil temperatures are OK.
Measurements:sgpswatsE5.b1:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, West Profile(soilwatpot_W)

SGP/SWATS/E5 - Sensor failure, 5cm E
DataStreams:sgpswatsE5.b1
Description:
The temperature rise on 5cm E profile are incorrect (> MAX QC test) beginning 20070623. 
This also causes the matric potential and water content data to be incorrect.
Measurements:sgpswatsE5.b1:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)

Subject:
SGP/SWATS/E5 - Sensor failure, 175cm E
DataStreams:sgpswatsE5.b1
Description:
The temperature rise of the 175-cm East profile began reporting as incorrect with values 
near 0 C. This also caused the matric potential and water content data to be incorrect.

On 10/28/08, a broken wire was fixed and data came back online.

Soil temperature data was unaffected.
Measurements:sgpswatsE5.b1:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)
