Description:	The EBBR barometer did not agree with the SMOS at all times. However this problem only rarely affected the sensible and latent heat flux values. Replacement of the barometer on 29 july 2003, 12 aug 2003, and 26 aug 2003 caused some obvious disruption in data flow.

DataStreams:	sgp15ebbrE8.a1, sgp15ebbrE8.b1, sgp30ebbrE8.a1, sgp30ebbrE8.b1, sgp5ebbrE8.a1
Description:	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.

DataStreams:	sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:	The net radiometer was covered with ice from a storm. Net radiation values are incorrect, and are sometimes even negative during the daytime. Sensible and latent heat fluxes are therefore incorrect.

Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E8 data collected by ARM back to the installation of the instrument in December 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 moisture units (from "by volume" to "gravimetric")
