The restart on 12/10/02 occurred after a CR10
program change of net radiometer coefficients 
and subsequent restart of the CR10.

SGP/EBBR/E12  - Water in Net Radiometer, Surface Fluxes 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/E12 - Pressure Sensor Measurement Scales With Battery Voltage

The barometer output was scaling with supply voltage (i.e. it 
               followed the charging of the battery by the solar panel).

               NOTE: The barometer was replaced later than the end date of 
               this DQR.  Why the problem ended on 26 Nov 2003 is unclear; 
               there was no site ops intervention on that date.

               The problem did not affect the sensible and latent heat flux 
               calculations beyond the expected system error.

SGP/EBBR/E12 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E12 data collected by ARM back to the installation of the 
instrument in August 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 type
4) Correction of soil moisture units (from "by volume" to "gravimetric")
