Dinosaur: Differentiable Dynamics for Global Atmospheric Modeling 🦖

Authors: Jamie A. Smith, Dmitrii Kochkov, Peter Norgaard, Janni Yuval, Stephan Hoyer

Dinosaur is an old-fashioned (some might say prehistoric) dynamical core for global atmospheric modeling, re-written in JAX to meet the needs of modern AI weather/climate models:

  • Dynamics: Dinosaur uses spectral methods to solve the shallow water equations and the primitive equations (moist and dry) on sigma coordinates.
  • Auto-diff: Dinosaur supports both forward- and backward-mode automatic differentiation in JAX. This enables "online training" of hybrid AI/physics models.
  • Acceleration: Dinosaur is designed to run efficiently on modern accelerator
    hardware (GPU/TPU), including parallelization across multiple devices.

For more details, see our paper Neural General Circulation Models for Weather and Climate.

Usage instructions

Dinosaur is an experimental research project that we are still working on
documenting.

We currently have three notebooks illustrating how to use Dinosaur:

We recommend running them using Google Colab with a GPU runtime.
You can also install Dinosaur locally: pip install dinosaur

SpeedyWeather.jl, which
solves similar equations in Julia.
