Dynamics for Global Atmospheric Modeling 🦖\n\nAuthors: Jamie A. Smith, Dmitrii Kochkov, Peter Norgaard, Janni Yuval, Stephan Hoyer\n\nDinosaur is an old-fashioned (some might say prehistoric) dynamical core for global atmospheric modeling, re-written in [JAX](https://github.com/jax-ml/jax) to meet the needs of modern AI weather/climate models:\n\n- *Dynamics*: Dinosaur uses spectral methods to solve the shallow water equations and the primitive equations (moist and dry) on sigma coordinates.\n- *Auto-diff*: Dinosaur supports both forward- and backward-mode automatic differentiation in JAX. This enables \"online training\" of hybrid AI/physics models.\n- *Acceleration*: Dinosaur is designed to run efficiently on modern accelerator\nhardware (GPU/TPU), including parallelization across multiple devices.\n\nFor more details, see our paper [Neural General Circulation Models for Weather and Climate](https://www.nature.com/articles/s41586-024-07744-y).\n\n## Usage instructions\n\nDinosaur is an experimental research project that we are still working on\ndocumenting.\n\nWe currently have three notebooks illustrating how to use Dinosaur:\n\n- [Baroclinic instability](https://nbviewer.org/github/neuralgcm/dinosaur/blob/main/notebooks/baroclinic_instability.ipynb)\n- [Held-Suarez forcing](https://nbviewer.org/github/neuralgcm/dinosaur/blob/main/notebooks/held_suarez.ipynb)\n- [Weather forecast on ERA5](https://nbviewer.org/github/neuralgcm/dinosaur/blob/main/notebooks/weather_forecast_on_era5.ipynb)\n\nWe recommend running them using [Google Colab](https://colab.research.google.com/) with a GPU runtime.\nYou can also install Dinosaur locally: `pip install dinosaur`\n\n## See also\n\nIf you like Dinosaur, you might also like\n[SpeedyWeather.jl](https://github.com/SpeedyWeather/SpeedyWeather.jl), which\nsolves similar equations in Julia.\n\n## Contributing\n\nSee [`CONTRIBUTING.md`](CONTRIBUTING.md) for details. We are open to user\ncontributions, but please reach out (either on GitHub or by email) to coordinate\nbefore starting significant work.\n\n## License\n\nApache 2.0; see [`LICENSE`](LICENSE) for details.\n","funding_links":[],"readme_doi_urls":[],"works":{},"citation_counts":{},"total_citations":0,"keywords_from_contributors":["neuralgcm","convolutional-neural-network","climate","weather","jax","bayesian-methods","probabilistic-programming","cfd","transformers","dataclass"],"project_url":"https://ost.ecosyste.ms/api/v1/projects/296158","html_url":"https://ost.ecosyste.ms/projects/296158"}
