Subject:	SGP/EBBR/E7 - Barometric Pressure Incorrect
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:	The pressure measurement sometimes dropped to zero during daytime because of unstable battery voltage.
Measurements:	sgp15ebbrE7.b1: atmos_pressure_mv sgp5ebbrE7.b1: Barometric Pressure(atmos_pressure) sgp30ebbrE7.b1: Barometric Pressure(atmos_pressure)

Subject:	SGP/EBBR/E7 - Fluxes and Gradient Measurements Incorrect
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:	The left AEM aspirator was not working during this period, resulting in incorrect gradient and flux measurements.

Subject:	SGP/EBBR/E7 - Windspeed threshhold too high
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:	The wind speed sensor developed worn bearings and therefore too high a starting threshhold. The data user should compare the EBBR wind speed with the SMOS wind speed to detect periods when the EBBR wind speed threshhold caused poor data quality.
Measurements:	sgp30ebbrE7.b1: wspd_arith_mean wspd_vec_mean sgp15ebbrE7.b1: wspd_arith_mean sgp5ebbrE7.b1: wspd_arith_mean wspd_vec_mean

Subject:	SGP/EBBR/E7 - Wind Speed Frozen Stopped
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:	Freezing rain stopped wind speed sensor.
