WeatherNext 3 adds hourly forecasts and five times sharper resolution using real-time satellite data
↗
Google DeepMind released WeatherNext 3, an AI weather model that produces hourly forecasts at five times the spatial resolution of WeatherNext 2 by ingesting raw satellite data instead of relying on traditional physics simulations.
Engineers can integrate higher-resolution, hourly-updated weather data into applications via Google Cloud and Google Maps Platform, replacing the coarser 6-hour interval forecasts of the previous model. The direct use of satellite observations rather than physics-based simulations marks a methodological shift, though the material does not specify pricing or access constraints for the Cloud API.

WeatherNext 3 generates hourly forecasts at 5-kilometer resolution for key surface variables, compared to WeatherNext 2's 25-kilometer grid with 6-hour increments.
The model ingests raw satellite data directly rather than relying on traditional physics-based simulations.
Forecasts are accessible through Google Search, Maps, Gemini, Google Maps Platform, and Google Cloud.
