# WeatherNext\n\n## WeatherNext 2\n\nThis repo contains the code for WeatherNext 2 (WN2), the global, medium-range\natmospheric and cyclone forecasting model developed by Google DeepMind and\nGoogle Research.\n\nIt also contains code for prior generation models\n[GraphCast](https://deepmind.google/blog/graphcast-ai-model-for-faster-and-more-accurate-global-weather-forecasting/)\nand\n[GenCast](https://deepmind.google/blog/gencast-predicts-weather-and-the-risks-of-extreme-conditions-with-sota-accuracy/).\n\n### Accessing Forecast Data Feeds\nIf you are interested in directly accessing daily data feeds of WN2 model\noutputs rather than running the model yourself, we provide them across multiple\nplatforms:\n\n*   [Google Cloud](https://developers.google.com/weathernext/guides/access-forecast)\n(including Earth Engine, BigQuery, and Vertex AI).\n*   [WeatherLab](https://deepmind.google.com/science/weatherlab) (including cyclone tracks).\n*   [OpenMeteo](https://open-meteo.com/en/docs/google-weathernext-api) (including an API and interactive builder).\n\n### Learn More\n\n*   **Model Guide & Documentation:** [Google Developers WeatherNext Guide](https://developers.google.com/weathernext/guides/models)\n*   **WeatherNext Cyclones Paper:** [Operational tropical cyclone forecasting\n    with AI](https://www.nature.com/articles/s41586-026-10953-2)\n*   **FGN/WN2 Technical Report:** [Skillful joint probabilistic weather\n    forecasting from marginals\n    (arXiv:2506.10772)](https://arxiv.org/abs/2506.10772)\n*   **WeatherNext 2 Blog Post:** [WeatherNext 2: Our most advanced weather forecasting model](https://blog.google/innovation-and-ai/models-and-research/google-deepmind/weathernext-2/)\n*   **WeatherNext Cyclones Blog Post:** [WeatherNext: AI model achieves breakthrough in forecasting cyclones](https://deepmind.google/blog/weathernext-ai-model-achieves-breakthrough-in-forecasting-cyclones/)\n\n### Older Models\n\nThis repository serves as the primary home for the Weathe
