NOAA Develops AI-Powered Sibling to Flagship Weather Model

NOAA’s pioneering High Resolution Rapid Refresh (HRRR) short-term weather forecast model will soon be joined by an experimental, AI-powered sibling. This month, NOAA’s Global Systems Laboratory is releasing HRRR-Cast, a data-driven model trained on three years of HRRR model data, for testing by NOAA’s National Weather Service. The HRRR has been the NWS’ flagship operational short-term forecast model for 10 years.HRRR-Cast is NOAA’s first regional experimental AI forecast system and a key component of NOAA’s broader Project EAGLE, a long-term project to provide NOAA and the U.S. weather enterprise with the ability to rapidly test, develop and identify the most promising AI models for
