SGP/SWATS/E4 - Incorrect soil moisture data
DataStreams:sgpswatsE4.b1
Description:
The temperature rise readings on both the east and west profiles are too high.  This also 
causes the matric potential and water content data to be incorrect.

For the first, third and fourth date ranges, measurements are incorrect for all sensor 
locations (each depth on both profiles).

For the second date range, measurements are incorrect for the lowest 8 sensor locations 
(the 60cm, 85cm, 125cm, and 175cm depths on both profiles).
Measurements:sgpswatsE4.b1:
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)

SGP/SWATS/E27 - Incorrect Soil Moisture Data
DataStreams:sgpswatsE27.b1, sgpswatsE27.00
Description:
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.
Measurements:sgpswatsE27.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Sensor Temperature Rise, West Profile(trise_W)

SGP/SWATS/E4 - Sensor failures, 5cm and 15cm W
DataStreams:sgpswatsE4.b1
Description:
The temperature rise readings from the 15-cm depth on the west profile were incorrect from 
20040212:1500 to 20040217:0800. This also caused the matric potential and water content 
data for the 15-cm depth to be incorrect.

The temperature rise readings from the 5-cm depth on the west profile were incorrect from 
20040217:2300 to 20040218:1900. This also caused the matric potential and water content 
data for the 5-cm depth to be incorrect.
Measurements:sgpswatsE4.b1:
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Volumetric Water Content, West Profile(watcont_W)

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.
Measurements:sgpswatsE27.b1:
  • Volumetric Water Content, East Profile(watcont_E)

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.

  • Soil Temperature, West Profile(tsoil_W)
  • Soil Water Potential, West Profile(soilwatpot_W)

failed.

SGP/SWATS/E27 - Incorrect soil temperature measurements
DataStreams:sgpswatsE27.b1
Description:
All of the tsoil measurements at this EF appear noisy and erratic at times, impacting all 
sensors and both profiles.
Measurements:sgpswatsE27.b1:
  • Soil Temperature, East Profile(tsoil_E)
  • Soil Temperature, West Profile(tsoil_W)

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

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.

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
  • Sensor Temperature Rise, East Profile(trise_E)
