convert gfs spectral, sfc and nemsio files to netcdf format

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.

gfstonc's Issues

Issue with using gfs_nemsiotonc

Hi:
I really appreciate it that you made this python package. After installation, I tried to use utils/gfs_nemsiotonc to convert the gfs ensemble data (nemsio) to netcdf data before I use python to read data from it. I was using gdas.t12z.sfcf006.mem014.nemsio and I got error message like: " problem with nemsio_readrecv(ps), iret= -42" . Do you know how I can fix this issue?

Version Release?

I've noticed from setup.py that this code is called v0.0.1 -- any plan to make that a release? I've been asked to install gfstonc on a server, and it is our policy to install only released software, so we can easily identify which version we are running.

Build failed

The build failed with the following error below. I was hoping someone had seen this before.
