Subject: | SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient |
DataStreams: | sgp30baebbrE19.c1 |
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) |
