Subject:	SGP/EBBR/E4 - Wind Speed Sensor Frozen By Ice Storm
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	The wind speed sensor was frozen stopped by ice from a storm. The wind speed and residual wind speed measurements are incorrect.

Subject:	SGP/EBBR/E4 - Wind Speed Frozen Stopped By Ice
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.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/E4 - Wind Direction Frozen Stopped By Ice
DataStreams:	sgp30ebbrE4.b1, sgp5ebbrE4.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.

Subject:	SGP/EBBR/E4 - Net Radiation Incorrect, Sensible and Latent Heat Fluxes Incorrect
DataStreams:	sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	The Net Radiometer domes were broken and rain entered, causing net radiation values to be too large during the period.

Subject:	SGP/EBBR/E4 - 6 Month Checks
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	Many measurements were incorrect while the AEM was positioned with both aspirators at the same height for comparison checks.

Subject:	SGP/EBBR/E4 - metadata corrections
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	On 20050817, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E4 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")
