  • Google DeepMind and Google Research introduced WeatherNext 3, an AI model that produces detailed hourly forecasts using real-time satellite data.
  • Google says the model performed best in an Operational WeatherBench test and improved rainfall prediction accuracy by 60% over WeatherNext 2.
  • The model will support Google products, business services and renewable-energy operators planning solar and wind generation.

Google’s new WeatherNext 3 model reads raw satellite images and updates weather forecasts every hour, rather than every six hours as the previous version did.

Google DeepMind and Google Research introduced the global AI weather model on Sept. 3. According to TechCrunch, WeatherNext 3 delivered the strongest results in Brightband’s Operational WeatherBench test, outperforming models from Microsoft, Nvidia, the European Centre for Medium-Range Weather Forecasts and the U.S. National Weather Service in accuracy.

The model has 2.4 times more parameters than WeatherNext 2. Google says its direct processing of raw satellite imagery removes the need for a supercomputer-based preprocessing step and improves rainfall forecast accuracy by 60% compared with the earlier version.

Senior Google engineer Samier Merchant said core weather variables from the AI model would, for the first time, feed several Google products, including Search, Google Maps and Gemini. Businesses can access WeatherNext 3 through BigQuery, Earth Engine, Google Maps Platform and Google Cloud Storage.

The system is also designed for industrial uses, particularly renewable energy. It can calculate solar radiation and cloud cover to help solar and wind power operators plan production. Earlier WeatherNext technology was tested by the U.S. National Hurricane Center to track and forecast the landfall of Hurricane Melissa in Jamaica.

This is the first time some core meteorological variables from an AI model have been used to provide data for multiple Google products.
