Hi,
New reference descriptions for netCDF formats have recently been added
to
Sustainability of Digital Formats
http://www.digitalpreservation.gov/formats/
This web site is in use for planning for US Library of Congress
collections.
Direct links to the format descriptions are:
NetCDF-3, Network Common Data Form, version 3
http://www.digitalpreservation.gov/formats/fdd/fdd000330.shtml
NetCDF-4, Network Common Data Form, Version 4
http://www.digitalpreservation.gov/formats/fdd/fdd000332.shtml
NetCDF-4C, Network Common Data Form, Version 4, Classic Model
http://www.digitalpreservation.gov/formats/fdd/fdd000339.shtml
Ben Domenico and I helped review these descriptions, but credit for the
clarity, completeness, and accuracy of the information about netCDF
should go to Caroline Arms, a Library of Congress contractor and
co-compiler of the resource.
I recommend these concise summaries of the netCDF format variants for
reference, comparison with other formats, and use in citations.
