Short Range Weather Application

The Unified Forecast System (UFS) is a community-based, coupled, comprehensive Earth modeling system. It is designed to be the source system for NOAA’s operational numerical weather prediction applications while enabling research, development, and contribution opportunities for the broader weather enterprise. For more information about the UFS, visit the UFS Portal.

The UFS includes multiple applications that support different forecast durations and spatial domains. This documentation describes the development branch of the UFS Short-Range Weather (SRW) Application, which targets predictions of atmospheric behavior on a limited spatial domain and on time scales from minutes to several days. The development branch of the application is continually evolving as the system undergoes open development. The latest SRW App release (v2.0.0) represents a snapshot of this continuously evolving system.

Releases

Release Date: 06/23/2022

Release Description: 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.
