Google released WeatherNext v3, its AI weather forecast model, with a key upgrade that now ingests raw satellite data alongside reanalysis data. This reduces the lag time between current atmospheric conditions and new forecasts, improving accuracy. The update bridges a gap between AI and traditional physics-based weather models by incorporating more real-time data sources.
Background
AI-powered weather models have emerged as a promising alternative to traditional physics-based numerical weather prediction, offering comparable accuracy at a fraction of the computational cost. Google's WeatherNext has been a leading example in this space since its initial release.
