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

Subject:	SGP/EBBR/E2 - AEM Ventilator Dangling - Sensible and Latent Heat Fluxes Incorrect
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The right AEM ventilator unit with temperature and humidity sensors inside was dangling from the AEM. Therefore, the gradients of temperature and relative humidity and thus sensible and latent heat flux are suspect for this period. Often, the fluxes look reasonable.
