Depends on how the files will be used. I should mention hdf5 or netcdf4
formats with OpenDAP clientsand servers. This supports discovery and
processing applications (Matlab and many others).
At work we are redesigning a legacy workflow that used externally
compressed hdf4 files with one based on netcdf4 with internal compression.
With the old workflow, users had to download the compressed files and
decompress for use, even if they wanted only a small subset of a file. The
new workflow should allow users to load a variety of subsets directly into
applications. The catch seems to be managing the metadata, but it is hard
to imagine that it could be worse than the old system where users often
needed lengthy email exchanges to get the metadata in a form they could use.
