gfstonc

python utilities and modules to read NCEP gfs spectral, surface and nemsio files and convert to netcdf.

numpy, netcdf4-python and gfortran are required, plus the shtns spherical harmonic transform library (including the python interface).

set the env vars SHTNS_LIBDIR and FFTW3_LIBDIR to point to where the shtns and fftw3 libraries are installed. fftw3 is required by shtns.
python setup.py build
- setup.py will try to build src/libw3nco_d.a and src/libbacio_4.a if they do not already exist.
python setup.py install (or python setup.py install --user to install in your home directory).

Will not work on Windows!

utils/gfs_spectonc converts gfs binary spectral files to netcdf (assumes the binary spectral data is big endian).

utils/gfs_sfctonc converts gfs binary surface files to netcdf (assumes the binary surface data is big endian).

utils/gfs_nemsiotonc_3d converts gfs 3d nemsio files to netcdf.

utils/gfs_nemsiotonc_2d converts gfs 2d nemsio files to netcdf.

Watch where setup.py installs the utility scripts, you will need to add that location to your $PATH.
