SGP/EBBR/E27 - Sensible and Latent Heat Fluxes Incorrect

The left T/RH probe temperature sensor was spiking some of the time during these periods. 
Therefore, sensible and latent heat fluxes were incorrect during parts of the periods as 
well.

SGP/EBBR/E22 - Fluxes Incorrect When Soil Heat Flow #3 Out of Range

measurements of vapor pressure gradient and thus calculations of sensible and latent heat 
flux.
