| Subject: | SGP/EBBR/E13 - Radiometer dome broken |
| DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1
|
| Description: | The top net radiometer dome was broken, yielding net radiation, sensible heat flux and
latent heat flux that were too low.
The BEFLUX (SIRS) net radiation can be used as a replacement for the EBBR net radiation.
To correct the sensible and latent heat fluxes, determine the ratio of SIRS net radiation
to EBBR net radiation for each daylight half hour and multiply that ratio times H and LE
to obtain approximate corrected flux values. |
