Hi Arild,

Yes. The copyright is contained in the src/COPYRIGHT file and permits
modifying and distributing the software under the conditions stated.
(We've released later software under the LGPL license, and might
consider doing the same for the decoders package if the current
COPYRIGHT is causing problems.)

Yes, we are very interested in your changes! They sound useful enough
that we might want to incorporate some of your enhancements in our
decoders package (with your permission and giving you credit), or at
least include a pointer to your web site from our decoders page, so
our users can access your enhanced versions. Please let us know if
this sounds practical.
I've had several requests for GRIB <-> netCDF conversion, and it looks
like you've provided a useful resource for those conversions.
And thanks on behalf of the Unidata community for your efforts
enhancing the decoders package and letting us know about your
improvements.
