SGP/EBBR/E20 - Soil Temperature and Soil Moisture  #4 Measurements Incorrect
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1
Description:
The ts4 sensor reported 99999 values because the sensor leads were loose.  Soil moisture 
#4 reported low values (steady 16%) during this time period.

The sensible and latent heat fluxes were not affected by this problem, only
soil temperature and soil moisture #4.  See soil temperatures and soil moistures from sets 
#2, #3, and #5 for correct values (note: soil temperature #1 was having problems during 
the same time).
Measurements:sgp30ebbrE20.b1:
  • volumetric soil moisture, site 4(sm4)
  • Soil heat capacity 4(cs4)
  • soil heat flow, site 4(g4)
  • 0-5 cm change in soil heat storage with time, site 4(ces4)
  • 0-5 cm integrated soil temperature, site 4(ts4)
sgp15ebbrE20.b1:
  • Soil temperature 4(rr_ts4)
  • Soil moisture 4(r_sm4)

SGP/EBBR/E20 - metadata corrections
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E20 data collected by ARM back to the installation of the 
instrument in April 1993. Please see the current metadata for correct information.  These 
changes do not
affect data values or quality.	

The changes are summarized below:
1) Update of "sensor location" information
2) Addition of installation dates for the systems
3) Correction of soil moisture units (from "by volume" to "gravimetric")
