- WeatherNext 3 can produce hourly forecasts with up to a 5-kilometer resolution, an upgrade from the previous 6-hour/25-kilometer resolution.
- The enhanced accuracy, up to 50% better for precipitation forecasts a day in advance, is particularly beneficial in areas with limited ground-based weather stations.
- The AI model is also designed to forecast renewable energy generation, such as wind speed at turbine height.
- WeatherNext 3 is integrated into Google products like Search, Maps, and Gemini, and Google is collaborating with weather agencies to improve forecasting.
