SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient

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)

SGP/EBBR/E19 - BA EBBR VAP Bulk Aerodynamics

Fixed AEM and wind speed sensor heights were improperly used in the
calculation of bulk aerodynamic sensible and latent heat fluxes instead of
site specific heights.
      
This resulted in either under-estimation or over-estimation of the sensible
and latent heat fluxes.
