SGP/SWATS/E10 - Reprocess: Changed Depth Dimension

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/E10 - Incorrect soil moisture

All temperature rise values were incorrect.  Soil moisture variables were also incorrect 
due to the incorrect T-rise values.  Soil temperature measurements were not affected.

SGP/SWATS/E6 - Sensor failure, 15-cm W

All variables from the 15-cm depth on the west profile are reporting as -9999.  Sensor has 
failed.

failed.

SGP/SWATS/E16 - Incorrect soil moisture

Sensors for all levels in both profiles were reporting values of temperature rise at or 
near 0 C.  The incorrect values of temperature rise result in incorrect soil moisture data.

SGP/SWATS/E10 - Sensor failure, 15cm W

All variables from the 15cm West sensor are reported as missing. The sensor has failed.

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

SGP/SWATS/E10 - Sensor failure, 15cm E

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.

• Soil Water Potential, East Profile(soilwatpot_E)
• Sensor Temperature Rise, East Profile(trise_E)

SGP/SWATS/E10 - Soil temperature irregular, 25cm W

The 25 cm W sensor was demonstrating temporal irregularities and were noisy at times.  
These irregularities consisted of dips and increases of around 2-4 C that typically started 
around 14:00 or 15:00 GMT on most days. On other days the values appeared somewhat noisy 
throughout the day. In both cases, the temporal changes did not compare well with the 
other sensors installed at E10.

A broken wire was repaired for 25cm W sensor.

SGP/SWATS/E16 - Sensor failure, 125cm E

Temperature rise values from the 125 cm E sensor began to intermittently drop out to 
values near 0 C starting at 4:00 GMT on 12/14 before permanently reporting values near 0 C at 
20:00 GMT on 12/15.  The incorrect values of temperature rise result in incorrect matric 
potential and water content data for these sensors.

Soil temperature for this sensor is not affected.

SGP/SWATS/E16 - Sensor failure, 125cm E

The 125cm East sensor reported temperature rise values at or about 0 for the duration of 
the specified period.

Soil temperature data were not affected.

SGP/SWATS/E16 - Sensor failure

The East 15 cm sensor began producing intermittent missing values between 5/6 and 5/11, 
and then consistently on 5/12 and after. This sensor has failed.

SGP/SWATS/E10 - Incorrect calibrations

After a power outage, an older version of the datalogger program was accidently installed 
on the SWATS, resulting in improperly calibrated soilwatpot and watcont values from all 
levels in both profiles for this time period.
