Original titleIntroducing WeatherNext 3, our most advanced and accurate global weather AI model
Google DeepMind and Google Research introduced WeatherNext 3, which generates hourly global forecasts at up to 5-kilometer resolution using live geostationary satellite data.
The company reports that precipitation forecasts improved by up to 60% against IMERG in medium-range evaluations, and that longer-range precipitation forecasts are up to 50% more accurate.
The model is now available across Search, Gemini, Google Maps, Google Maps Platform Weather API, Google Earth Engine, BigQuery, and Google Cloud Storage.
The post explains how training on live satellite data and station observations changes resolution and update frequency, with precipitation accuracy gains reported against named baselines.
