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

Subject:
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.

SGP/SWATS/E19 - Sensor failure, 60cm E
DataStreams:sgpswatsE19.b1
Description:
The 60cm East profile sensor began reporting temperature rise values near 0 C. This 
problem continued until the old profile of sensors was disconnected and the new set of sensors 
was connected. The soil temperature measure was not impacted by this problem.

SGP/SWATS/E5 - Sensor failure, 125cm W
DataStreams:sgpswatsE5.b1
Description:
Both the temperature rise and soil temperature measures of the 125-cm W profile are 
reported as -9999 since 10/07/99. This sensor has been essentially dead since then, and all 
associated variables are impacted.

DataStreams:sgpswatsE5.b1
Description:
The temperature rise of the 175cm W profile began reporting as incorrect with values near 
0 C on 20010817. This also causes the matric potential and water content data to be 
incorrect.

Soil temperature data are not affected.
