NetCDF File Format
Data in netCDF format is self describing and bundles geophysical variables as well as metadata in a file format that can be easily read by different programming languagues and tools. We use v4 of the netCDF format that supports compression of its content to minimize file sizes.
Global Attributes
The global attributes of the netCDF file provide metadata such as citation, reference, time coverage and more. Use ncinfo filename.nc
or tools like panoply to list the global attributes.
