Accelerating advances in our nation’s
operational forecast modeling systems

EPIC will continually inform and accelerate advances in our nation’s operational forecast modeling systems.

The Unified Forecast System (UFS) Community is creating a new experience for scientists, joining forces for the benefit of life.

The EPIC Program and Virtual Center will deliver world-class numerical weather prediction systems supporting NOAA.

The UFS Community and EPIC Program

NOAA is using a community modeling framework to develop their operational modeling systems. The Unified Forecast System (UFS) is composed of component systems – these could be model components or infrastructure components – and applications that connect some or more of these components together to make a computational model and bundle it with an end-to-end workflow.
