SGP/SWATS/E4 - Incorrect soil moisture data
DataStreams:sgpswatsE4.b1
Description:
The temperature rise readings on both the east and west profiles are too high.  This also 
causes the matric potential and water content data to be incorrect.

For the first, third and fourth date ranges, measurements are incorrect for all sensor 
locations (each depth on both profiles).

For the second date range, measurements are incorrect for the lowest 8 sensor locations 
(the 60cm, 85cm, 125cm, and 175cm depths on both profiles).
Measurements:sgpswatsE4.b1:
  • Sensor Temperature Rise, East Profile(trise_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, West Profile(trise_W)
  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, West Profile(watcont_W)

incorrectly entered into the ARM database.  The correct location
of the SWATS.E19 instrument is:
   Lat: 35.557N

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.
