Subject:	SGP/EBBR/E19 - Battery Voltage Too Low, Most Measurements Incorrect
DataStreams:	sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:	Battery voltage dropped below levels required to sustain the production of valid data. The AC charger unit had failed. This prevented charging of the battery during the night and prevented the solar panel regulator from properly charging the battery during the day.

DataStreams:	sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:	The AEM home 15 and 30 outputs were both 40 mv because the AEM was not exchanging. Sensible and Latent Heat Fluxes are therefore incorrect.

DataStreams:	sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:	An ice storm froze the wind speed sensor to a stopped condition. It is not known how long this condition existed, as data is missing for more than 10 days after the end of the stated period. The wind speed and residual wind speed measurements are incorrect. This sensor failure does not affect the sensible and latent heat fluxes.

DataStreams:	sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1

Subject:	SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient
DataStreams:	sgp30baebbrE19.c1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:	The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage calibration) was incorrect. Negative net radiations during the subject period can be multiplied by 0.9419 to get corrected net radiation measurements. The sensible (H) and latent heat (LE) fluxes (which are very small at night anyway) can be recalculated using the following equations (where B is Bowen ratio, Rn is corrected net radiation, and G is soil heat flow): LE = -(Rn + G)/(B + 1) H = -(Rn + G + LE)
