[ncl-talk] Possible to convert grib2 or netcdf files to grib1?

Hi Mary & Guilherme,

Thanks for the replies. When I run 'make' in my cnvgrid-3.1.0 directory I
get the following error:

In file pds2pdt.f:50


        use params

                  1

Fatal Error: Can't open module file 'params.mod' at (1) for reading: No
such file or directory



I think the ultimate problem lies with my not being able to install g2lib;
when I attempt to do so, I get the error:

m2c    -o g2grids.o g2grids.mod

make: m2c: No such file or directory


and inserting the line %.o : %.mod results in a different error:


make: *** No rule to make target `libg2.a(g2grids.o)', needed by
`libg2.a'.  Stop.


The problem is probably simple, but I've yet to make any headway on these
errors.



Regarding wgrib2, I found examples and documentation of using it to convert
grib1 to grib2, but not vice versa. If you could kindly provide guidance on
how the conversion to grib1 could be done using wgrib2 (if possible), I'd
greatly appreciate it.


Best regards,

Colin
