python/numpy interface to netCDF library (versions 3 and 4)
netCDF version 4 has many features not found in earlier versions of the library and is implemented on top of HDF5. This module can read and write files in both the new netCDF 4 and the old netCDF 3 format, and can create files that are readable by HDF5 clients. The API modelled after Scientific.IO.NetCDF, and should be familiar to users of that module.
Most new features of netCDF 4 are implemented, such as multiple unlimited dimensions, groups and zlib data compression. All the new numeric data types (such as 64 bit and unsigned integer types) are implemented. Compound data types are supported, but variable length data types (vlen, strings) are not, nor are the enum and opaque data types, mainly because they do not map easily onto any numpy data type.
This project has a Subversion repository where you may access the most up-to-date source.
