Subject:	SGP/EBBR/E20 - Pressure Sensor Data Incorrect
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The E20 pressure sensor suffered from spikes in pressure, which were related to increases in voltage during the day as the solar panels charged the battery. These spikes were not of a magnitude that would affect the 30 minute surface fluxes. Replacement of the pressure sensor solved the problem.

DataStreams:	sgp15ebbrE20.b1, sgp30baebbrE20.c1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The left air temperature, and therefore top and bottom air temperatures were offscale or incorrect on occasion. Bowen ratio, sensible heat flux, and latent heat flux were also incorrect during those times. Inspection of the data is required to detect the incorrect periods.

DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The wind direction sensor was stuck at about 100 degrees. This did not affect the primary measurements (net radiation, soil heat flow, sensible heat flux, latent heat flux).

DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E20 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")
