Unified Forecast System

Applications and Components

UFS configurations that support particular forecast requirements are called applications. Each application combines a numerical model, data assimilation, post-processing, workflow, and other elements. Each distinct software element of an application is called a component.

Current UFS applications and the types of guidance they are expected to provide are listed below
