HRRR-Smoke is the first weather forecast model in the U.S. to include smoke’s impact on weather, and it has been operating experimentally out of NOAA’s Global Systems Laboratory in Colorado since 2016. Earlier this month, after more than a year of rigorous testing, HRRR’s smoke forecasting capabilities were transitioned to NOAA’s National Centers for Environmental Prediction, where thousands of computer processors power a fleet of weather models. There, HRRR-smoke now runs around the clock, producing a new weather and smoke forecast every hour.
