ufs2arco

Conda version PyPI version OS Support Python Documentation Status

ufs2arco is a python package that is designed to make NOAA forecast, reanalysis, and reforecast datasets more accessible for scientific analysis and machine learning model development. The name stems from its original intent, which was to transform output from the Unified Forecast System (UFS) into Analysis Ready, Cloud Optimized (ARCO; Abernathey et al., (2021)) format. However, the package now pulls data from a number of non-UFS sources, including GFS/GEFS before UFS was created, and even ECMWF's ERA5 dataset.

Installation

Recommended: Install from conda-forge

Given that some ufs2arco dependencies are only available on conda-forge, it's recommended that users install using this method

conda install -c conda-forge ufs2arco

This will install all underlying dependencies, including mpi4py which by default installs mpich for MPI support. If a different MPI distribution is desired, for example Intel MPI, then this can be installed via:

conda install -c conda-forge ufs2arco impi_rt

in the exact same way as directed in this section of the mpi4py documentation.

Install from conda-forge without MPI

If you do not want to install MPI through conda-forge, for instance if you want to use an MPI distribution that is already built on a system you're using, then it is recommended to install the nompi build from conda-forge as follows:

conda install -c conda-forge ufs2arco=*=nompi*

Then, one can install mpi4py from pip using these instructions, or following instructions specific to your machine.

Install from pip

It is possible to install ufs2arco from pypi via:

pip install ufs2arco

However, this will not come with the MPI or xesmf dependencies, since these need to be installed from conda-forge.
