Google's New AI Weather Model Uses Live Satellite Data For Higher
Engadget • • business
Key Points:
- Google DeepMind has launched WeatherNext 3, an enhanced AI-powered weather model providing more detailed forecasts for temperature, moisture, and wind speed, aimed particularly at renewable energy sectors.
- The model offers hourly forecasts with higher resolution, using a 5-kilometer grid compared to the previous 25-kilometer grid in WeatherNext 2, enabled by training on new data sources.
- Unlike prior models reliant on numerical weather prediction data with a six-hour delay, WeatherNext 3 integrates live satellite data for continuously updated atmospheric insights.
- Incorporating sparse weather station data allows the model to deliver finer forecasts for variables like humidity, which can vary significantly over short distances.
- By combining precipitation data from NASA and Google satellites, WeatherNext 3 improves rain and snow predictions by up to 50%, especially in regions where forecasts were previously less reliable.
