[GEMPAK #KRJ-399065]: Configuring GEMPAK/NAWIPS for Local Model

Brent,

The PD# is the "Product Definition Template" number. This allows you
the flexibility to define a parameter uniquely depending on the
sampling, average, accumulation etc.

For example, you will see for precipitation:

000 001 008 008 Total precipitation              kg m**-2             P--M      
       0     -0.01
000 001 008 009 Precipitation Probability        %                    PP--      
       0  -9999.00
000 001 008 019 Precipitation Below Normal       %                    PPBN      
       0  -9999.00
000 001 008 029 Precipitation Near Normal        %                    PPNN      
       0  -9999.00
000 001 008 039 Precipitation Above Normal       %                    PPAN      
       0  -9999.00

The precipitation rate error you have is that the value of "8" specifies the 
mean precipitation
rate over the period, whereas, if yours is "0", you would need to add an entry 
for
an instantaneous precipitation rate which is valid at the one moment in time. 
It can have the same
name as another- but is not restricted to that as if the PD# were ignored.
