SGP/EBBR/E27 - Reference T Sensor Failure

all other temperature sensors.  Sensible and latent heat fluxes
were incorrect when this occurred.

SGP/EBBR/E27  - Water in Net Radiometer; Surface Fluxes are Incorrect

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

SGP/EBBR/E27 - Missing data during system update

Some soil parameters were slightly incorrect since EBBR.E27 was 
                 installed in May 2003.  While the coefficients were being updated,
                 data collection was suspended resulting in missing data for the 
                 specified period.
                    No significant effects (1% or less) on the surface heat flux data 
                 would have occurred from using the slightly incorrect coefficients. 
                 Therefore, flagging of the surface flux data from the time of 
                 installation of E27 is unwarranted.

SGP/EBBR/E27 - metadata corrections

On 20050816, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E27 data collected by ARM back to the installation of the 
instrument in May 2003. 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")

SGP/EBBR/E27 - Multiplexer #2 failure

A problem with the #2 Multiplexer caused a large number of measurements to be incorrect.  
Sensible and latent heat fluxes were often affected.

SGP/EBBR/E27 - Measurements offscale

All J-panel 4 measurements (soil heat flows, net radiation, air temperatures, home 
signals, pressure, vapor pressure) were sometimes offscale or otherwise incorrect.  J-Panel was
