SGP/SWATS/E7 - Sensor failure, 35cm E
DataStreams:sgpswatsE7.b1
Description:
The 35-cm East sensor had several problems before failing permanently in 2007:

20061208.2000-20070306.2000: temperature rise reported values of -9999, and soil 
temperature reported abnormally high temperature values.  

20070813.1200-20070912.1300: all variables reported as -9999, including soil temperature.  
A very small number of soil temperature values were reported as unusually high 
temperature values after 09/10/07.

20070912.1300-20070915.1600:  incorrect values of temperature rise reported (near 0 C), 
and soil temperature values incorrect and unusually high.

20071110.0000-20071115.2300:  incorrect values of temperature rise reported near 0 C or 
unusually low.  Values of soil temperature OK.  

20071128.0000-->:  Except for two very brief recoveries (on the order of a few days), all 
35cm E variables are reported as -9999.

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)

SGP/SWATS/E19 - Sensor failure, 5cm E
DataStreams:sgpswatsE19.b1
Description:
After the new refurbishment sensors were hooked up, the 5 cm E sensor began reporting 
values of -9999 for all variables.
Measurements:sgpswatsE19.b1:
  • Volumetric Water Content, East Profile(watcont_E)

SGP/SWATS/E19 - Sensor failure, 60cm W
DataStreams:sgpswatsE19.b1
Description:
The West 60 cm sensor began producing missing values at variable times on 5/11/2010, then 
consistently. It appears the sensor failed.  This facility was shutdown 5/24 following a 
tornado event.
Measurements:sgpswatsE19.b1:
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Volumetric Water Content, West Profile(watcont_W)

Subject:
SGP/RAIN/C1 - Incorrect precipitation measurements
DataStreams:sgprainC1.b1
Description:
RAIN TBRG precipitation measurements were significantly lower than accumulated 
precipitation measured by co-located ORG and MET instruments. This occurred in both light and heavy 
rain events.  

The tipping bucket sensor was replaced by a weighing bucket rain gauge.
Measurements:sgprainC1.b1:
  • Rainfall rate(rain_rate)
  • Precipitation(precip_tbrg)
