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.

Subject:	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.

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.

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. 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.
