Subject:	SGP/EBBR/E20 - Soil Temperature and Soil Moisture #4 Measurements Incorrect
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1
Description:	The ts4 sensor reported 99999 values because the sensor leads were loose. Soil moisture #4 reported low values (steady 16%) during this time period. The sensible and latent heat fluxes were not affected by this problem, only soil temperature and soil moisture #4. See soil temperatures and soil moistures from sets #2, #3, and #5 for correct values (note: soil temperature #1 was having problems during the same time).
Measurements:	sgp30ebbrE20.b1: energy_storage_change_4 soil_moisture_4 soil_temp_4 soil_heat_capacity_4 surface_soil_heat_flux_4 sgp15ebbrE20.b1: soil_temp_4_rr soil_moisture_4_rr

Subject:	SGP/EBBR/E20 - metadata corrections
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")

Subject:	SGP/EBBR/E20 - Reprocess: Wind Direction 20 Degrees Low
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The EBBR wind direction was found to be misaligned 20 degrees low. This bias should have had no effect on the res_ws or sigma_wd measurements.

Subject:	SGP/EBBR/E20 - Reprocess: Wind Direction 65 Degrees Low
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	The wind direction sensor reported wind directions that were 65 degrees too low because of a mis-alignment. This bias should have no effect on the res_ws or sigma_wd measurements. The wind direction data could be re-processed by adding 65 degrees.
Measurements:	sgp30ebbrE20.b1: wdir_vec_mean sgp15ebbrE20.b1: wdir_vec_mean_mv sgp5ebbrE20.b1: wdir_vec_mean
