[AWIPS #AMB-223808]: Model Precip data question

From our best understanding, model precip data (specifically) is something that 
AWIPS calculates
as a derived product on the EDEX side.  For some reason, it seems to not be 
consistent between 
model sources and is a complicated process.  Unfortunately, we do not 
understand it well at all.
The only place I could direct you would be the processing files for the 
existing models:
 /awips2/edex/data/utility/common_static/base/grib/postprocessing

I'm sorry this is an area we do not have much expertise in.  If you are able to 
make any progress
please feel free to report back.

Thanks.
