Short-range weather forecast model and starter data (NOAA UFS SRW)
What it measures. This is the prediction system and accompanying input files for forecasting local atmospheric weather from minutes out to several days, over a limited region. The package includes the model itself plus the terrain, land-use, and starting-condition files it needs to run.
How it's made. NOAA built it as the Short-Range Weather application of its community Unified Forecast System, bundled with a model, pre- and post-processing tools, and a ready-to-run example case.
How & where you'd use it. It lets meteorologists, students, and developers run their own short-term regional weather forecasts and learn how a modern forecasting system works end to end. This is a modeling toolkit and its raw inputs, not a finished forecast you can simply read off.

Official description
The "Unified Forecast System (UFS)" is a community-based, coupled, comprehensive Earth Modeling System. It supports " multiple applications" with different forecast durations and spatial domains. The UFS Short-Range Weather (SRW) Application figures among these applications. It targets predictions of atmospheric behavior on a limited spatial domain and on time scales from minutes to several days. The SRW Application includes a prognostic atmospheric model, pre-processor, post-processor, and community workflow for running the system end-to-end. The "SRW Application Users's Guide" includes information on these components and provides detailed instructions on how to build and run the SRW Application. Users can access additional technical support via the "UFS GitHub Discussions" This data registry contains the data required to run the “out-of-the-box” SRW Application case. The SRW App requires numerous input files to run, including static datasets (fix files containing climatological information, terrain and land use data), initial condition data files, lateral boundary condition data files, and model configuration files (such as namelists). The SRW App experiment generation system also contains a set of workflow end-to-end (WE2E) tests that exercise various configurations of the system (e.g., different grids, physics suites). Data for running a subset of these WE2E tests are also included within this registry. Users can generate forecasts for dates not included in this data registry by downloading and manually adding raw model files for the desired dates. Many of these model f
