The UFS WM v2.0.0 is the latest public release of this software and represents a snapshot of a continuously evolving system undergoing open development. Key architectural elements of the Weather Model include:
The Weather Model is currently used in NOAA’s operational Global Forecast System (GFS). Additionally, the UFS Short-Range Weather (SRW) Application uses the fully coupled Weather Model in its v2.0.0 release (June 2022), and the UFS Medium-Range Weather (MRW) Application can run the WM in coupled or atmosphere-only mode.
The UFS WM code is portable and can be used with Linux and Mac operating systems and with Intel and GNU compilers. It has been tested on a variety of platforms widely used by atmospheric scientists, including NOAA’s Hera system, the National Center for Atmospheric Research (NCAR) Cheyenne system, and the Mississippi State University (MSU)/NOAA Orion system.
Those wishing to contribute to the development of the UFS WM should become familiar with the procedures for running the model as a standalone component and for executing the regression tests described in the UFS WM GitHub wiki to make sure that no inadvertent changes to the results have been introduced during the development process.
Support for the UFS WM is provided through the UFS WM Forum by the Developmental Testbed Center (DTC) and other groups involved in UFS development, including NOAA’s Environmental Modeling Center (EMC), NOAA research laboratories (GFDL, NSSL, ESRL, and AOML), the Earth Prediction Innovation Center (EPIC), and NCAR. UFS users and developers are encouraged not only to post questions but also to help address questions posted by other members of the community. More information about the UFS Community can be found on the UFS Community Portal.
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.
