SGP/SWATS/E1 - Reprocess: Wrong Calibration
DataStreams:sgpswatsE1.00, sgpswatsE1.a1, sgpswatsE1.b1
Description:
Two sensor connections were switched. The East 125-cm sensor was plugged into the East 
85-cm sensor's connection, and vice versa. Technicians corrected the problem on 1440 GMT, 
08/02/00, and returned the instrument to service 10 minutes later at 1450 GMT. As the 
datalogger was confusing the 2 sensors, incorrect calibrations were applied.

The correct calibrations can be applied to the raw data to obtain the correct temperature 
rises, soil moisture, etc. However, this is a rather large amount of work to apply toward 
just 1 measurement profile.  This has been identified as a medium priority reprocessing 
task.
Measurements:sgpswatsE1.a1:
  • East profile sensor serial numbers(serial_numbers_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Temperature, East Profile(tsoil_E)
sgpswatsE1.00:
  • null(Raw data stream - documentation not supported)
sgpswatsE1.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • East profile sensor serial numbers(serial_numbers_E)
  • Soil Water Potential, East Profile(soilwatpot_E)
