Welcome to the UFS Weather Model wiki!

The ufs-weather-model repository contains the model code and external links needed to build the Unified Forecast System (UFS) atmospheric model and associated components, including the WaveWatch III model. This weather model is used in several of the UFS applications, including the Medium-Range Weather Application and the Short-Range Weather Application.

This wiki includes a Getting Started section that leads you through a quick example. It also includes a Developer Information page with information on the the Commit Queue, testing, and recent updates.

Documentation and User Support

The UFS Weather Model (WM) User's Guide has more comprehensive information than this wiki, including links to scientific descriptions of the code and more thorough technical instructions.

Depending on what you are doing, you may need different versions of the User's Guide:

Version Description
Latest Documentation for the head of the development. This may have gaps and errors.
Tag ufs-srw-v2.2.0-doc Documentation for the version of the UFS WM used in the most recent UFS Short-Range Weather App release (v2.2.0)
Tag ufs-srw-v2.1.0 Documentation for the version of the UFS WM used in the UFS Short-Range Weather App v2.1.0 release
Tag ufs-srw-v2.0.0 Documentation for the version of the UFS WM used in the UFS Short-Range Weather App v2.0.0 release
Tag ufs-v2.0.0 Documentation for the version of the UFS WM used in the UFS Short-Range Weather App v1.0.0 release
Tag ufs-v1.1.0 Documentation for the version of the UFS WM used in the Medium-Range Weather App v1.1.0, the Getting Started section, and the Graduate Student Test.

You can also get expert help through a user support forum set up specifically for the UFS Weather Model.

Developer Information

The Developer Information page includes information on the hierarchical repository structure, developer support, and testing.

The ufs-weather-model Hierarchical Repository Structure

The ufs-weather-model repository supports several UFS applications. It contains atmosphere, ocean, sea ice, NEMS data atmosphere, CDEPS, stochastic physics, CMEPS mediator and wave components along with some infrastructure components. Each of these components has its own repository. All the repositories are currently located in GitHub with public access to the broad community. Below is the ufs-weather-model hierarchical repository structure:

The name of each component appears in bold, and the text below indicates the organization and repository on GitHub where the source code resides. The ufs-weather-model currently uses Git submodules to manage the subcomponents. Developers may need to work with several components at the same time and need to commit their changes to the components' authoritative repositories. To do that, developers need to follow the code management practices of the authoritative repositories. Once the components' authoritative repositories have been updated, the changes will be brought into the ufs-weather-model repository by its code managers.

Users who only need to check out the latest code or certain tags can clone the repository without having a GitHub account:

% git clone https://github.com/ufs-community/ufs-weather-model
% cd ufs-weather-model
% git checkout develop (or tags)
% git submodule update --init --recursive

Developers who are making code changes will need to refer to the Weather Model User's Guide. They will need to create a GitHub account if they do not already have one.
