incorrect. From 1907 on the 10th to 2007 on the 11th, correct tsoil_W data is available 
except for missing data at the 15cm depth.

trise_W:
All trise_W data is incorrect or missing from 1007Z on the 7th to 1807Z on the 10th. From

SGP/SWATS/E12 - Time drift
DataStreams:sgpswatsE12.b1, sgpswatspcpE12.b1
Description:
The time synchronization server stopped working on Feb. 19th at 22:12:16 GMT.  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.

SGP/SWATS/E12 - Reprocess: Changed Depth Dimension
DataStreams:sgpswatsE12.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/E12 - Incorrect soil moisture
DataStreams:sgpswatsE12.b1
Description:
Temperature rise values were 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 temperature 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.

Soil temperature measurements were not affected.
Measurements:sgpswatsE12.b1:
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Volumetric Water Content, West Profile(watcont_W)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)

SGP/SWATS/E15 - Incorrect soil moisture
DataStreams:sgpswatsE15.b1
Description:
At 20:00 GMT on 05/07/08, temperature rise data from ALL sensors on both profiles began 
reporting values of temperature change near 0 C. These incorrect values of temperature rise 
result in incorrect soil moisture data for all sensors. 

Soil temperature data are unaffected.

  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
