Google's WeatherNext 3 Ditches Physics, Learns from Live Satellite Data at 5km Resolution
Google Research and DeepMind are releasing WeatherNext 3, a weather model that skips traditional physics simulations and learns directly from real-time satellite data. It produces hourly forecasts at up to five-kilometer resolution, five times more detailed than its predecessor. Google says regions in Africa, Latin America, and the Asia-Pacific that have lacked accurate forecasts should see the biggest gains. This shift from physics-based to data-driven modeling could make forecasts faster and more accurate, especially in data-sparse regions.
