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.

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.

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.

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.

was repeated 100 times in both the raw and cdf data sets. The
duplicate records were removed.

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.

  • Volumetric Water Content, East Profile(watcont_E)
  • Soil Temperature, East Profile(tsoil_E)
  • Sensor Temperature Rise, East Profile(trise_E)

The temperature rise readings from the 15-cm depth on the west profile (trise_W) are 
incorrect. This also causes the matric potential (soilwatpot_W) and water content (watcont_W) 
data for the 15-cm depth to be incorrect.
