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. --Russ
