NETCDF_MPAS
MPAS Grid Files in NETCDF Format

NETCDF_MPAS is a data directory which contains examples of MPAS grid files, stored using the NETCDF format.

NETCDF provides a program called ncdump which can be used to create a text version of the data, or to extract the header information. Since the data files are often enormous, it is usually the header information that is most useful, and this information has been extracted and provided separately for the example files given here.
