SGP/EBBR/E15  - Wind Speed Frozen Stopped By Ice Storm
DataStreams:sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1

An ice storm froze the wind speed sensor to a stopped condition.

The wind speed and residual wind speed measurements are incorrect.

This sensor failure does not affect the sensible and latent heat fluxes.

SGP/EBBR/E15 - Net Radiation Too Large - Water in Bottom
DataStreams:sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1
Description:
Water in the bottom dome of the net radiometer made the measurements incorrectly large.  
Sensible and latent heat fluxes were therefore 
incorrect.

SGP/EBBR/E15 - metadata corrections
DataStreams:sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E15 data collected by ARM back to the installation of the 
instrument in September 1992. 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")

DataStreams:sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1
Description:
The top dome of the net radiometer was broken, resulting in net radiations that were too 
small, and thus sensible and latent heat fluxes that were too small.
