SGP/SWATS/E1 - Reprocess: Wrong Calibration
DataStreams: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.

  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)

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).

20040212:1500 to 20040217:0800. This also caused the matric potential and water content

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

SGP/SWATS/E7 - Sensor failure, 35cm E
DataStreams:sgpswatsE7.b1
Description:
The 35cm East profile data spiked out of range on 20040106. Soil temperature is incorrect 
at 0407 GMT, and all 35cm E data are incorrect at 0407 and 0507 GMT.

The 35cm East profile sensor failed on 20040127 around 1300 GMT. All data from this sensor 
are incorrect or missing until 20040208.

The 35cm East temperature rise readings were noisy and inconsistent with the rest of the 
data 20040317-20040623. This also caused the matric potential and water content data to be 
suspect.

The 35cm East soil temperature measurements were incorrect beginning 20041223 to 9:07 on 
12/24. Temperature rise, soil-water potential, and water content are incorrect from from 
the same start time to 11:07 GMT on 12/24.

DataStreams:sgpswatsE13.b1
Description:
See below for details of reprocessing that was completed on 20150814.  Original DQR 
category: 5 (Transparent - Does not affect quality).

-----------------------------------------------------------

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/E8 - Sensor failure, 35cm W
DataStreams:sgpswatsE8.b1
Description:
The sensor installed at 35 cm at the west profile has produced questionable data ince it 
was installed back in 1996.  Once the sensor began to stabilize at 17:00 GMT on 07/20/99, 
it has produced questionable or incorrect values of temperature rise.  From 07/20/99 to 
the present date, 35cm W temperature rise values have stayed within a range of 
approximately 0.8-2.0 C, while the sensor from the 35cm E profile has produced an approximate range 
of 1.5-4.0 C.

In addition, the calibration for this sensor is so bad it is not possible to correct it 
using field data.  The range of temperature rise values produced by this sensor is too 
limited to reliably re-calibrate the instrument.  Under the old ARM calibration for SWATS, 
the calibrated reference temperature change should fall within a range of 1.45-4.00 C (the 
new range is 1.38-3.96 C).  For this sensor, the reference temperature change has fallen 
within an approximate range of 0.2-1.7 C and the calibration is actually adjusting the 
trise measurements in the wrong direction.  

Therefore, all temperature rise, matric potential and water content data 
are all highly suspect from the 35cm W sensor.

The soil temperature data appear to be OK.

Instrument removed from service 20091110.

DataStreams:sgpswatsE10.b1
Description:
The 15cm E sensor failed at 7:00 GMT on 06/02/2002. Values of temperature rise from this 
sensor often do not fail automated QC tests, but inspection of the time series reveals 
that the values are incorrect. Since 2002, this sensor has alternated between providing 
temperature rise values near 0 C, equal to -9999, or other obviously incorrect values. 

Soil temperature data are not affected.
