SGP/EBBR/E8 - Reprocess: E8 EBBR Program Compile Error, Effect On Net Radiation
DataStreams:sgp30ebbrE8.b1, sgp15ebbrE8.b1, sgp5ebbrE8.b1
Description:
An error in CR10X program compilation occurred when new software was used
to perform the compilation.  The new software created an erroneous data table
listing, which the program works off of.  An incorrect data location was
used in the adjustment of net radiation for wind speed, causing all net
radiation values to be divided by 2. The following data was incorrect during
the period above:

5 minute:  q

15 minute: mv_q

30 minute: q, e, h

The latent and sensible heat fluxes can be corrected by recomputing as follows:

e = -(2q + ave_shf)/(1 + bowen)

h = -(e + ave_shf + 2q)
Suggestions: 
Recalculate latent and sensible heat fluxes using the equations provided.
