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:
  • Soil Water Potential, East Profile(soilwatpot_E)
  • serial_numbers_E
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Temperature, East Profile(tsoil_E)
sgpswatsE1.00:
  • 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)
  • serial_numbers_E
  • Soil Water Potential, East Profile(soilwatpot_E)

SGP/SWATS/E19 - Metadata Errors
DataStreams:sgpswatsE19.a1, sgpswatsE19.b1, sgpswatspcpE19.a1
Description:
The latitude, longitude and altitude of the El Reno (E19) site were
incorrectly entered into the ARM database.  The correct location
of the SWATS.E19 instrument is:
   Lat: 35.557N
   Lon: 98.017W
   Alt:    421m

SGP/SWATS/E24 - Reprocess: Changed Depth Dimension
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.
Measurements:sgpswatsE24.b1:
  • depth

SGP/SWATS/E8 - Sensor failure, 15cm W
DataStreams:sgpswatsE8.b1
Description:
The 15cm West profile sensor was not producing reasonable values of matric potential or 
water content.  Site ops found and tighten a loose wire.
Measurements:sgpswatsE8.b1:
  • Volumetric Water Content, West Profile(watcont_W)
  • Soil Water Potential, West Profile(soilwatpot_W)

SGP/SWATS/E8 - Incorrect soil moisture
DataStreams:sgpswatsE8.b1
Description:
Sensors in both profiles and at all depths were not being heated properly (temperature 
rise is too small). As a result, all matric potential and water content data are invalid 
also.
Measurements:sgpswatsE8.b1:
  • Volumetric Water Content, East Profile(watcont_E)
  • Volumetric Water Content, West Profile(watcont_W)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Sensor Temperature Rise, East Profile(trise_E)
  • Soil Water Potential, West Profile(soilwatpot_W)
