eccodes compatible local definitions (grib tables) for NCEP WMO Grib2 #293

Open emfdavid opened 9 months ago

emfdavid commented 9 months ago

I am working with the HRRR & GFS grib2 files via NODD. I would like to use CFGRIB to read your products, but I can't seem to find any local definitions that implement the recent NCEP WMO GRIB2 Documentation?

My colleague has also started a rust grib reader which is built by hand from the NCEP WMO doc - it looks similar to some of the fortran code in this repo.

Any assistance in building a machine readable table format (I don't love the eccodes format but it exists and has an implementation) to go with the PDF would be most appreciated.

Have you looked at the NCEPLIBS-g2tmpl project? Perhaps it contains what you need.

Have you looked at the NCEPLIBS-g2tmpl project? Perhaps it contains what you need.

So that NCEPLIBS-g2tmpl implements the NCEP grib spec in Fortran90. Is it possible to dump the definitions in a machine readable form (json?) from that library? Or would we need to write a fortran application or an f2py wrapper to access the table definitions?

I would like have this in a machine-readable format. However it's not clear how that will happen yet.
