Subject:
SGP/EBBR/E26 - Incorrect soil type coefficients used
DataStreams:sgp30ebbrE26.b1
Description:
The soil type coefficents for soil moisture were incorrect from the day
of the system installation on, making soil moisture values too large.

As a result, soil heat flows were overmeasured, and sensible and latent heat fluxes were 
underestimated.
Suggestions: 
Multiply sensible and latent heat fluxes by 1.02 as a rough correction.
