Welcome to JAX-GCM’s documentation!¶
JAX-GCM is a differentiable atmospheric general circulation model written in JAX. It couples the Dinosaur spectral dynamical core to modular SPEEDY, Held-Suarez, and ECHAM-style physics packages.
For the current beta release line, the main target configuration is ECHAM
physics on the T63L47 hybrid grid with RRTMGP radiation
(physics=echam-rrtmgp grid=echam_t63_l47_hybrid). The SPEEDY package
remains the lightweight default for quick tests, tutorials, and
optimization examples.
Note
New development targets the dev branch. Tagged release candidates
and clean releases are promoted through main.
