Subject:	SGP/EBBR/E2 - Wind Speed Frozen Stopped By Ice
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	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.

Subject:	SGP/EBBR/E2 - Wind Direction Frozen Stopped By Ice
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The wind direction sensor was frozen stopped by ice from a storm. The wind direction, sigma_wd, and residual wind speed measurements are incorrect.

DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The top dome of the net radiometer was broken and water entered, causing incorrect net radiation measurements. This resulted in incorrect sensible and latent heat fluxes.

Subject:	SGP/EBBR/E2 - metadata corrections
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E2 data collected by ARM back to the installation of the instrument in May 1997. 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")

Subject:	SGP/EBBR/E2 - Windspeed sensor failure
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
