NetCDFF

The Unidata network Common Data Form (netCDF) is an interface for scientific data access and a set of freely-distributed 
software libraries that provide an implementation of the interface. The netCDF library also defines a machine-independent format for representing scientific data.
Together, the interface, library, and format support the creation, access, and sharing of scientific data.
This software package provides Fortran application interfaces for accessing netCDF data. It depends on the netCDF C library, which must be installed first. Other separate software distributions available from Unidata provide C Java, C++, and Python. They have been tested on various common platforms.
