SGP/EBBR/E15 - Sensible and Latent Heat Fluxes Low
(Net Radiation too low)

Sensible and Latent Heat Fluxes were measured as being low because of damage to the net 
radiometer.

The Sensible and Latent Heat fluxes can be approximated by taking the ratio of the daytime 
SIRS net radiation to EBBR net radiation, and then multiplying the Sensible and Latent 
Heat Fluxes by that ratio.

SGP/EBBR/E9 - Sensible and latent heat flux incorrect

Sensible and latent heat fluxes were sometimes incorrect when soil temperature 4 and soil 
moisture 4 were acting up.

Sometimes the sensible and latent heat fluxes are indicated as incorrect by an offscale 
reading produced by the data logger error checking routine.  This occurs mostly during 
daytime.  However, you will have to examine the soil moisture 4 and soil temperature 4 data 
to see when they were incorrect or offscale to determine all times for which sensible and 
latent heat fluxes were incorrect.
