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.

SGP/EBBR/E8 - Failed Temp/RH sensor
DataStreams:sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The right Temperature-Humidity sensor failed. The measured temperature gradients were 
incorrect and thus the sensible and latent heat fluxes were incorrect for this extended 
period.

The sensor was replaced March 6.

SGP/EBBR/E4 - Reprocess: Wind Direction Incorrect
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
The wind direction was misaligned by 180 degrees. If the wind direction was 180 degrees or 
less, add 180 degrees to give the correct direction.  If the wind direction was greater 
than 180 degrees, subtract 180 degrees to give the correct direction.

and at other times trended correctly with the co-located SMOS but differed from it by 15
