NVIDIA launches Earth-2 open weather AI models for global forecasting

NVIDIA Corporation (NASDAQ: NVDA) announced the launch of its Earth-2 family of open weather and climate AI models at the American Meteorological Society's Annual Meeting. The company describes this as the first fully open, accelerated weather AI software stack.

The Earth-2 family includes three new models. Earth-2 Medium Range uses Atlas architecture to provide weather predictions up to 15 days in advance across more than 70 weather variables. Earth-2 Nowcasting employs StormScope architecture to generate kilometer-resolution storm forecasts within zero to six hours. Earth-2 Global Data Assimilation utilizes HealDA architecture to produce initial atmospheric conditions in seconds on GPUs rather than hours on supercomputers.

These models join existing Earth-2 offerings including CorrDiff for downscaling weather predictions and FourCastNet3 for high-accuracy forecasting. The platform also integrates open models from the European Centre for Medium-Range Weather Forecasts, Microsoft and Google.

Several organizations are implementing Earth-2 models operationally. The Israel Meteorological Service reports a 90% reduction in compute time at 2.5-kilometer resolution compared to traditional numerical weather prediction models. Weather AI provider Brightband is using Earth-2 Medium Range for daily global forecasts.

Energy companies including TotalEnergies, Eni and GCL are testing the models for forecasting applications. Southwest Power Pool, working with Hitachi, is using Earth-2 for wind forecasting to support grid operations.

Financial firms S&P Global Energy and AXA are utilizing Earth-2 models for risk assessment and hurricane scenario generation, according to the company statement.

Earth-2 Medium Range and Nowcasting models are available through NVIDIA Earth2Studio, Hugging Face and GitHub. Earth-2 Global Data Assimilation is scheduled for release later this year.
