24 June 2022: Short-Range Weather (SRW) Application v2.0.0

Release Notes

The UFS Community is proud to announce the public release (version 2.0.0) of the UFS Short-Range Weather Application. This newly updated weather application is designed for short-range (up to two days) regional forecasts located anywhere on the globe. It contains the Common Community Physics Package (CCPP) v6.0.0, version 10.1.0 of the Unified Post Processor (UPP) and version 3.0.0 of the UFS Weather Model. Documentation has been significantly enhanced and numerous test cases with all associated data files are now available to the public. The application is highly portable and detailed instructions describe how to build and run on a wide variety of platforms, including Ubuntu Linux and MacOS.

Documentation: User's Guide v2.0.0

Known Issues

  • On MacOS, users must run brew install bash before using brew to upgrade bash. MacOS users also need to run brew install gsed.

  • Bash/dash issue: On some systems, .sh points to bin/dash instead of bin/bash. On these systems, users can run sed -i -e 's/bin\/sh/bin\/bash/g' *.sh to resolve the issue.

  • On Gaea: The staged data path in regional_workflow/ush/machine/gaea.sh must be updated from ncep to ncep_shared if users do not have access to the ncep directory. To do this, change staged_data_dir to "/lustre/f2/pdata/ncep_shared/UFS_SRW_App/v2p0/".

  • When users build the HPC-Stack for use with the SRW App v2.0.0, they should clone the HPC-Stack srw-public-v2 branch as follows:

    git clone -b release/srw-public-v2 https://github.com/NOAA-EMC/hpc-stack.git

  • Known WE2E Test Failures: Some failed tests will pass if run a second time individually. The following tests consistently fail:
