Nvidia launches open, accelerated weather models and toolsAI weather and climate prediction is more accessible than ever for scientists, startups, developers, enterprises and government agencies worldwide. At the American Meteorological Society’s Annual Meeting, Nvidia this week unveiled a new Nvidia Earth-2 family of open models, libraries and frameworks for weather and climate AI, offering the world’s first fully open, accelerated weather AI software stack. AI-powered weather forecasting saves significant computational time and costs, allowing more nations, weather enterprises and businesses to run application-specific forecasting systems. Earth-2 also integrates open models from the European Centre for Medium-Range Weather Forecasts (ECMWF), Microsoft, Google and others. In addition, Earth-2 models can be trained and fine-tuned using Nvidia PhysicsNeMo, an open-source Python framework for developing AI-physics models at scale.
