Subject:	SGP/SWATS/E7 - Sensor failure
DataStreams:	sgpswatsE7.00, sgpswatsE7.b1
Description:	First time range: The readings from the 35-cm depth on the east profile spiked out of range on 20040106 (YYYYMMDD). Soil temperature (tsoil_E) is incorrect at 0407 GMT, and all data (tsoil_E, trise_E, soilwatpot_E, watcont_E) are incorrect at 0407 and 0507 GMT. Second time range: The sensor at the 35-cm depth on the east profile failed on 20040127 around 1300 GMT. All data from this sensor are incorrect or missing until 20040208.
Measurements:	sgpswatsE7.00: null(Raw data stream - documentation not supported) sgpswatsE7.b1: Volumetric Water Content, East Profile(watcont_E) Soil Temperature, East Profile(tsoil_E) Sensor Temperature Rise, East Profile(trise_E) Soil Water Potential, East Profile(soilwatpot_E)

Subject:	SGP/SWATS/E8 - Incorrect Soil Moisture Data
DataStreams:	sgpswatsE8.00, sgpswatsE8.b1
Description:	The temperature rise readings from the 15-cm depth on the east profile (trise_E) are incorrect. This also causes the matric potential (soilwatpot_E) and water content (watcont_E) data for the 15-cm depth to be incorrect.
Measurements:	sgpswatsE8.b1: Sensor Temperature Rise, East Profile(trise_E) Volumetric Water Content, East Profile(watcont_E) Soil Water Potential, East Profile(soilwatpot_E) sgpswatsE8.00: null(Raw data stream - documentation not supported)

Subject:	SGP/SWATS/E12 - Incorrect Times
DataStreams:	sgpswatsE12.00, sgpswatsE12.b1, sgpswatspcpE12.b1
Description:	The ntpd server (time adjustment) stopped working on Feb. 19th at 22:12:16 GMT, and the clock was corrected by -5600.177269 seconds on March 10th at 22:47 GMT. The recorded times for observations are off by amounts ranging from 0 seconds on Feb. 19th to 5600 seconds on March 10th.

Subject:	SGP/SWATS/E7 - Incorrect Soil Temp and Moisture Data
DataStreams:	sgpswatsE7.00, sgpswatsE7.b1
Description:	The soil temperature and temperature rise readings from all depths on both the east and west profiles (tsoil_W, tsoil_E, trise_E, trise_W) were incorrect. This also caused the matric potential (soilwatpot_E, soilwatpot_W) and water content (watcont_E, watcont_W) data to be incorrect. The reference temperature reading (tref) is suspect.

Subject:	SGP/SWATS/E7 - Incorrect Soil Moisture Data
DataStreams:	sgpswatsE7.00, sgpswatsE7.b1
Description:	The temperature rise readings from the 35-cm depth on the east profile (trise_E) are noisy and inconsistent with the rest of the data. This also causes the matric potential (soilwatpot_E) and water content (watcont_E) data for the 35-cm depth to be suspect.

Description:	Due to a collection malfunction, the data for timestamp 153700 was repeated 1700+ times in both the raw and cdf data sets. The duplicate records were removed.
Measurements:	sgpswatsE6.b1: Time offset of tweaks from base_time(time_offset) sgpswatsE6.a1: Time offset of tweaks from base_time(time_offset) sgpswatsE6.00: null(Raw data stream - documentation not supported)

Subject:	SGP/SWATS/E7 - Incorrect Temperature and Moisture Measurement on the East Profile at 35cm Depth
DataStreams:	sgpswatsE7.b1
Description:	Problem is for the east profile, 35cm depth only: soil temperature measurements were incorrect from 7:07 GMT on 12/23 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/E12 - T_rise higher than QC checks
DataStreams:	sgpswatsE12.b1
Description:	T-rise way to high (~40 deg C). Water potential is calculated from a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees C. When the T_rise is too high, the soil moisture data is dubious at best and unusable at worst. Since this "out-of-bounds" t_rise is so high, the soil moisture data are practically unusable.

Subject:	SGP/SWATS/E10 - Incorrect temperature rise
DataStreams:	sgpswatsE10.b1
Description:	All the temperature rise values were incorrect (trise_W, trise_E). Soil moisture variables are also incorrect due to the incorrect T-rise values. Soil temperature measurements are not affected.
