Google Launches WeatherNext 3 for Hourly AI Forecasts

KEY FACTS

  • Google DeepMind has introduced the WeatherNext 3 model, enabling hourly updates for high-resolution global weather forecasts.
  • The model achieves a surface variable resolution of 5 kilometers and an atmospheric variable resolution of 25 kilometers, trained on real-time satellite data.
  • By leveraging sparse observation data to overcome computational limits, it delivers localized, precise forecasts for regions including Latin America and Africa.
  • New features include renewable energy predictions that estimate wind speeds at 100 meters and solar radiation levels.
  • The model is integrated into core Google products such as Search, Maps, Gemini apps, and Earth Engine starting immediately.
