Subject:	SGP/EBBR/E18 - 6 Month Checks
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:	Many measurements were incorrect while the AEM was positioned with both aspirators at the same height for comparison checks.

Subject:	SGP/EBBR/E18 - Wind Speed Frozen Stopped By Ice Storm
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.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/E18 - Wind Direction Frozen Stopped By Ice Storm
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.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/E18 - Net Radiation Incorrect; Sensible and Latent Heat Fluxes Incorrect
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:	The net radiometer top dome was broken and water got inside, making the net radiation, and sensible and latent heat flux measurements incorrect.

Subject:	SGP/EBBR/E18 - metadata corrections
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E18 data collected by ARM back to the installation of the instrument in July 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 type 4) Correction of soil moisture units (from "by volume" to "gravimetric")

Subject:	SGP/EBBR/E18 - Wind Speed Zero
DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:	Wind Speed was zero, presumably because the sensor was frozen stopped during freezing rain.

DataStreams:	sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:	The net radiometer dome was cracked and water had gotten in, resulting in incorrect net radiation measurements and therefore incorrect sensible and latent heat flux measurements.
