Who We Are
The Earth Prediction Innovation Center (EPIC) is a collaboration within the Weather Enterprise – government, industry, and academia — to improve weather forecasting systems, and empower the UFS. It is being spearheaded by the National Oceanic and Atmospheric Administration (NOAA) along with its contracting partner, Raytheon.

News and Events

In environmental analysis and prediction, data assimilation (DA) is the process that combines observations with model data to produce a best estimate of the Earth system state at a given time, also known as the analysis. DA systems are critical to providing analyses both for nowcasting and situational awareness, as well as for the initialization of numerical weather prediction (NWP) and Artificial Intelligence-based (AI) forecast systems. As significant as advances in DA capabilities has been over recent decades, such as expanding the types of observations assimilated and the environmental phenomena observed, many challenges still exist.
