Subject:	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.

Subject:	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.

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.

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.

Subject:	SGP/SWATS/E10 - Sensor failure, 15cm E
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.

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. Instrument removed from service 20091102.

Subject:	SGP/SWATS/E27 - Incorrect serial numbers
DataStreams:	sgpswatsE27.b1
Description:	The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. This issue impacts the following variables but does not impact data quality: serial_numbers_W, serial_numbers_E. All serial numbers stored in the serial_numbers_W variable apply to data stored in the trise_E and tsoil_E variables, and vice versa. Thus, the user should be aware that the trise_W, trise_E, tsoil_W, and tsoil_E variables actually contain data from the opposite profile.
