What happened
Nvidia introduced three new AI weather tools: Earth-2 Medium Range, Nowcasting, and Global Data Assimilation, as part of its Earth-2 family of open models. These tools collectively enhance the accuracy of weather forecasts, with Earth-2 Medium Range outperforming existing models on over 70 variables for up to 15-day predictions. This development expands the capability for precise atmospheric prediction and broadens the accessibility of advanced forecasting models to a wider user base, altering previous limitations on forecast precision and user reach within the operational environment.
Why it matters
The increased accessibility of advanced forecasting models introduces a tightened dependency for platform operators on Nvidia's AI ecosystem for critical weather intelligence. This also raises the oversight burden for data governance and risk management functions to ensure the integrity and appropriate application of these newly accessible, high-accuracy forecasts, potentially weakening the control over data provenance and model validation.
