We don’t need the whole functionality, just a basic writing. But anyway it’s still a bunch of work. the latest 4.0 library supports writing netcdf-3 large files, but not netcdf-4. i doubt performance is a good enough reason to do all that work, but it would be interesting to see some timings. > > > > Could you comment a little bit about possible issues?

We are experimenting with JNA, which uses reflection to make the programming easier, at the cost of some efficiency. > > > > Thanks, > > Mark Balonkin > > > > > > > >>Hi all: > >> > >>There is no release date on NetCDF 4 write capabilities, as we are still >>evaluating its feasibility.
