The next release of Win32 GrADS due sometime this summer will very
likely include grads2/gradsdap binaries. In the meantime, search the
list as someone has contributed a grads 2.0.a2 binaries.

Also, Win32 GrADS v1.9.0-rc1 comes with an extension that allows you
to read grib2. At this point you are better off using it with perl
from cygwin.  Info on Win32 GrADS is here:

The g2 extension is documented here:

and comes bundled with Win32 GrADS.
