The Earth Prediction Innovation Center (EPIC) and the Unified Forecast System (UFS) community are proud to announce the public release of the Short-Range Weather Application (SRW App) version 2.2.0. This release is an update to the version 2.1.0 release from November 2022 and reflects a number of changes currently available in the SRW App develop branch. The Application is designed for short-range (up to two days) regional forecasts located anywhere on the globe. The new release includes the following updates:

• Bug fixes since the v2.1.0 release
• Addition of the supported FV3_RAP physics suite (PR #811) and support for the RRFS_NA_13km predefined grid
• Addition of FV3_GFS_v17_p8 physics suite (PR #574)
• Updates to CCPP that target the top of the main branch (which is ahead of CCPP v6.0.0). View a detailed summary of CCPP updates that came in ahead of the SRW App v2.2.0 release.
• Expansion of Level 1 platforms to include Derecho, Hercules, and Gaea C5 (PRs #894, #898, #911)

• Integration of the Unified Workflow’s templater tool (PR #793)
• Ability to create a user-defined custom workflow (PR #676)
• Option to use a custom vertical coordinate file with different distribution of vertical layers (PR #813) and documentation on how to use this feature (PR #888)
• Incorporation of plotting tasks into the workflow (PR #482); addition of ability to plot on both CONUS and smaller regional grid (PR #560)
• Addition of a sample verification case (PR #500) with documentation
• A new tutorial chapter in the documentation (PR #584)
• Incorporation of UFS Case Studies within the WE2E framework (PRs #736 and #822)
• Air Quality Modeling (AQM) capabilities (unsupported but available; see PR #613)
