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.

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.

SGP/EBBR/E20 - Wind Direction Incorrect
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The wind direction differed from the co-located SMOS by 50 deg during part of the stated 
period and the electronics had failed completely resulting in a constant 135 degrees for 
the following dates and times:
08/15 0230-0430, 0830-1530 and 09/03 0200-0300, 0500 - 09/10 2230.

Sensible and latent heat fluxes were not affected by this problem.
