Subject:
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)

Subject:
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

Subject:
SGP/SWATS/E27 - Reprocess: Miscalibration
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.
Measurements:sgpswatsE27.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Soil Water Potential, West Profile(soilwatpot_W)
