The first Unified Forecast System (UFS) Users’ Workshop took place on July 27-29, 2020 from 11 AM to 5 PM Eastern Time (ET), with the aim of establishing an annual forum to exchange scientific ideas, advance education on applying the UFS, to explore ways that UFS is being applied to weather, climate, and related types of prediction, and to convene the full potential of the community to support and improve the UFS. It featured engagement and discussions with diverse groups of participants from across the Weather Enterprise including public and private sectors, academia, and those involved in operations, all of whom share a common interest in delivering the best forecasts to many stakeholders. The workshop expected to improve communication, transparency, and mutual trust between operational centers and the broader community.
A community-based, coupled Earth modeling system, the UFS, is under active development to support the Weather Enterprise and to be the source system for NOAA's operational numerical weather prediction forecasts. The UFS numerical applications span local to global domains and predictive timescales from sub-hourly analyses to seasonal predictions. The first application released was the UFS Medium-Range Weather (MRW) Application, which targets atmospheric behavior out to approximately two weeks. The release included the Finite-Volume Cubed-Sphere (FV3) dynamical core, the Common Community Physics Package (CCPP) with four supported physics suites, including the current operational and developmental Global Forecast System (GFS) physics suites, pre-processing utilities, the Unified Post Processor (UPP), and a workflow to build and run the global forecast system. To ensure architectural flexibility and portability, the UFS uses modernized software and infrastructure, providing an opportunity for all parties to share and contribute information in a consistent and up-to-date manner.
For the broadest community engagement, the UFS Users’ Workshop:
Informed the attendees of the most recent updates to the UFS including programmatic and technical status, and perspectives.
Informed the community on the capabilities of the UFS and how the community can contribute to the development and improvement of the UFS.
Showcased experiences related to various aspects of the modeling system (atmosphere, ocean, sea ice, dynamics, physics, data assimilation, verification, etc.) and range of applications (short-term up to seasonal, global, regional, hurricane, air quality, etc.).
Built a platform for the next generation of scientists to become involved with the UFS, providing continued enhancement of the operational forecast system.
