The temperature rise readings from all depths on both the east and west profiles (trise_E, 
trise_W) are incorrect. This also causes the matric potential (soilwatpot_E, 
soilwatpot_W) and water content (watcont_E, watcont_W) data to be incorrect.

SGP/SWATS/E27 - Reprocess: Incorrect calibrations
DataStreams:sgpswatsE27.b1
Description:
The calibration coefficients for the 5-cm sensor on the East profile are
incorrect. This is causing incorrect soil water content (watcont_E) to be
reported.

DataStreams:sgpswatsE24.b1
Description:
The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.

SGP/SWATS/E27 - Sensor failure, 85cm W
DataStreams:sgpswatsE27.b1
Description:
The 85 cm West sensor (based on location in the multiplexer) at this facility appears to 
have failed.  After initially demonstrating problems in mid-2006, all variables from this 
sensor began to report as -9999 on and after 7:00 GMT on 08/04/06.  

Note, although this sensor is listed as 85 cm W in the data files due to its location in 
the multiplexer, it is actually the 85 cm E sensor in the ground.  

Instrument removed from service 20091204.
Measurements:sgpswatsE27.b1:
  • Soil Temperature, West Profile(tsoil_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Volumetric Water Content, West Profile(watcont_W)

sensors and both profiles.

SGP/SWATS/E27 - Incorrect serial numbers
DataStreams:sgpswatsE27.b1
Description:
The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. This issue 
impacts the following variables but does not impact data quality: serial_numbers_W, 
serial_numbers_E.

All serial numbers stored in the serial_numbers_W variable apply to data stored in the 
trise_E and tsoil_E variables, and vice versa.  Thus, the user should be aware that the 
trise_W, trise_E, tsoil_W, and tsoil_E variables actually contain data from the opposite 
profile.
Measurements:sgpswatsE27.b1:
  • serial_numbers_E
  • serial_numbers_W

DataStreams:sgpswatsE27.b1
Description:
The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. Matric 
potential and water content data are incorrect due to incorrect calibrations being applied to 
temperature rise sensor data.

SGP/SWATS/E27 - Sensor failure, 125cm E
DataStreams:sgpswatsE27.b1
Description:
The 125 cm E sensor tsoil measurements were very erratic and much too high, and all trise 
values were reporting as slightly negative or -9999.  The issue started on 06/07 and 
corrected itself by 20:00 GMT the same day, but the problem returned on 06/10.  Connections 
were re-seated on 6/17 to resolve the problem.
Measurements:sgpswatsE27.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)
  • serial_numbers_W
