Introducing WeatherNext 3, our most advanced and accurate global weather AI model

Google DeepMind and Google Research introduced WeatherNext 3, rated the most accurate global weather model to date in independent live evaluations by Brightband. The model learns from real-time geostationary satellite data and sparse weather station observations, producing hourly forecasts at up to 5-kilometer resolution—roughly five times sharper than WeatherNext 2's 25-kilometer grid. It adds predictions for renewable energy, including 100-meter wind speeds and cloud cover, and improves precipitation forecasting using NASA IMERG satellite data.
