Subject:	SGP/EBBR/E2 - Sensible and Latent Heat Fluxes Incorrect
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The sensible and latent heat fluxes and the gradient measurements were incorrect during this period because the AEM did not switch positions properly.

Subject:	SGP/EBBR/E2 - Windspeed sensor failure
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The windspeed sensor developed an abnormally high wind speed threshold due to worn bearings. Wind speeds were often measured to be too low. Inspect the data to identify suspect time periods.

Subject:	SGP/EBBR/E2 - Net Radiation and Fluxes Incorrect
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The net radiometer was tipped 37 degrees eastward, resulting in apparent solar noon being 2.5 hours early. The net radiation error results in incorrect sensible and latent heat fluxes.
Measurements:	sgp5ebbrE2.b1: net_radiation sgp15ebbrE2.b1: net_radiation_mv sgp30ebbrE2.b1: net_radiation latent_heat_flux sensible_heat_flux
