Kevin,
I think the Garp problem exists where the developers of Garp copied over
their own version of a GEMPAK file and modified it for their uses-
unfortunately, that means it has to be edited separately to enjoy the
new features of GEMPAK (recall, Garp isn't part of GEMPAK).
In: $GARPHOME/gempak/readimgdata.c, the switch ( imgtyp ) section
about line 107, needs an option:
case IFNCDF: /* NetCDF files */
crncdf ( filnam, &ier ) ;
break;
I will include that in my 5.6.B release in a few weeks.
Are you building from source? Or have you downloaded a binary that I provided?
I can send you a binary if the latter is the case. Since I don't have any
NetCDF images to test on,it would be nice if I could test it out on
one of your images if you want me to send you a binary.
