We have a very preliminary version of netcdf-java 4.0 at:
You can do this programatically, or just use the ToolsUI Viewer (version 4.0)
(Just open the files in the Viewer tab. To dump data, select the variable and right click
and select "NCdump data". If running from webstart, its a good idea to have the
Java Console running so you can see any error messages.)
We are looking for problems with any valid netcdf4 / hdf5 file that exists,
including hdf5 1.8+, npoess, hdf5-eos, etc (sorry, no hdf4 files!). Please let
us know what problems you see, along with a test file.
Thanks for any testing help that you can provide!
