Hi guys,
I have created a couple of pull requests (one for 2.4.x and one for trunk)
for NetCDF output support.
https://github.com/geoserver/geoserver/pull/345
https://github.com/geoserver/geoserver/pull/344
I have also created pull request for the community module to include the
NetCDF coverage support as downloadable item (Right now, it can be
triggered within the geoserver war through a netcdf profile).
https://github.com/geoserver/geoserver/pull/346
https://github.com/geoserver/geoserver/pull/347
Cheers,
Daniele
