Nvidia announced three new AI weather tools today. Together, they promise to improve the accuracy of weather forecasts while also making them accessible to more users.
TL;DR
- Nvidia's new Earth-2 AI models aim to make weather forecasting faster and more accurate.
- The Earth-2 Medium Range model reportedly surpasses Google DeepMind's GenCast AI weather model.
- The Earth-2 suite includes Nowcasting for short-term predictions and a Global Data Assimilation model that significantly reduces preparation time for forecasting.
- These new models utilize simpler, scalable transformer architectures, moving away from niche AI designs.
- The tools are intended to democratize access to advanced weather forecasting, historically limited to wealthier entities.
- Existing Earth-2 models include CorrDiff and FourCastNet3.
- Meteorologists in Israel and Taiwan are using Earth-2 CorrDiff, and companies like The Weather Company and Total Energies are evaluating Nowcasting.
