The ufs-weather-model repository contains the model code and external links needed to build the Unified Forecast System (UFS) model and associated components.
A Getting Started section leads you through a quick example. A Graduate Student Test is also available for students, postdocs and others to provide feedback on the usability of the UFS by running through a series of experiments and then filling out a questionnaire about the experience. Participate now!
UFS can be configured into multiple applications — to-date, two have been formally released to the community: the Medium-Range Weather (MRW) Application and, more recently, the Short-Range Weather (SRW) Application. The table below provides links to App user guides, code repositories and wikis.
| Release Name | Release Date | Release Description |
|---|---|---|
| UFS Short-Range Weather Application 2.0 GitHub Wiki GitHub Repository Users Guide |
06/23/2022 | The SRW Application v2.0.0 includes a prognostic atmospheric model, pre- and post-processing, and a community workflow for running the system end-to-end. These components are documented within this User’s Guide and supported through a community forum (https://forums.ufscommunity.org/). New and improved capabilities for this release include the addition of a verification package (METplus) for both deterministic and ensemble simulations and support for four Stochastically Perturbed Perturbation (SPP) schemes. Future work will expand the capabilities of the application to include data assimilation (DA) and a forecast restart/cycling capability. |
