Hi,
Dennis Shea graciously provided me with an NCL script to convert the
RUC GRIB to netCDF.
Regards,
Steve

I am not sure how many files u need to do.
Is this going to be "operational" and under time constraints?
The way u were mimicking was the 'classic' way where the user must
predefine the file's contents before writing anything.
This must be done in all other languages: fortran, C, IDL, matlab,...
I am attaching an NCL script that does things in a very simple manner
but can be quite slow. I call it the "simple but (possibly very)
inefficient"
approach to writing netCDF from GRIB.
The reason ... well u have to know something about how NCL implements
the underlying netCDF software.
NCL allows a file to be written *without* being predefined.]
It is written for just one file ... Try it as is.
I'm sure u can implement it within the original frame work.
I will look at the more efficient approach when I have time.
Regards
Dennis
