#11 en IA pour les sciences & la biologieAccelerated Understanding · 2× · vu le 27 août 2026
FourCastNet is a data-driven AI model by NVIDIA (part of NVIDIA Earth-2) for global weather and climate forecasting, based on Adaptive Fourier Neural Operator and Spherical Fourier Neural Operator architectures. It predicts atmospheric and surface variables such as wind speed, temperature, and pressure with 6-hour time steps while maintaining stable forecast quality over simulated periods of more than one year. The current version FourCastNet 3 delivers probabilistic ensemble forecasts that compete with leading physics-based weather models and is available via NVIDIA NIM as a microservice as well as through Hugging Face/NGC as a model. It is deployed commercially and non-commercially for meteorology, climate research, and early warning systems.
