DataStreams:	sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:	Residual Moisture left in the top dome of the net radiometer after the 8/17/05 servicing caused the net radiation measurements to be biased low, and resulting in sensible and latent heat flux being low also.

Subject:	SGP/EBBR/E27 - metadata corrections
DataStreams:	sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:	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")
