SGP/SWATS/E18 - Intermittent data
DataStreams:sgpswatsE18.b1
Description:
There is an erroneous measurement at 2052Z on the 11th. All obs should be disregarded and 
probably should be deleted from the file.

tsoil_W:
From 1007Z on the 7th to 1707Z on the 9th: tsoil_W data is missing or incorrect at the 5cm 
depth. From 1807 on the 9th to 1807 on the 10th, tsoil_W is completely missing and/or 
incorrect. From 1907 on the 10th to 2007 on the 11th, correct tsoil_W data is available 
except for missing data at the 15cm depth.

trise_W:
All trise_W data is incorrect or missing from 1007Z on the 7th to 1807Z on the 10th. From 
1907 on the 10th to 2007 on the 11th, trise_W data is missing at the 15cm depth.

tsoil_E:
From 1007 on the 7th to 1907 on the 9th, trise_E data is missing or incorrect except at 
the 5cm depth. From 2007 on the 9th to 1907 on the 10th, tsoil_E data is missing.

trise_E:
From 1007 on the 7th to 1907 on the 10th, trise_E data is missing or incorrect.

SGP/SWATS/E16 - Incorrect soil moisture
DataStreams:sgpswatsE16.b1
Description:
Sensors for all levels in both profiles were reporting values of temperature rise at or 
near 0 C.  The incorrect values of temperature rise result in incorrect soil moisture data.
Measurements:sgpswatsE16.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • 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.

SGP/SWATS/E16 - Sensor failure, 125cm E
DataStreams:sgpswatsE16.b1
Description:
Temperature rise values from the 125 cm E sensor began to intermittently drop out to 
values near 0 C starting at 4:00 GMT on 12/14 before permanently reporting values near 0 C at 
20:00 GMT on 12/15.  The incorrect values of temperature rise result in incorrect matric 
potential and water content data for these sensors.

Soil temperature for this sensor is not affected.  

Sensor resumed working 20090425.
Measurements:sgpswatsE16.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
