Experimental code

The openghg_inversions.experimental namespace contains runnable model variants and integration prototypes that are useful for scientific comparison and future API design, but are not part of the stable public API.

Warning

Experimental modules may change or be removed without a deprecation period. Their inputs and results should be treated as research interfaces rather than production contracts. Importing the namespace does not retrieve data or start sampling.

Experimental code is kept separate from production model builders so that it can:

• preserve scientifically useful historical behavior;

• test requirements for planned generic interfaces;

• use current preparation, coordinate, prior, and sampling infrastructure; and

• carry focused tests and validation evidence without changing stable results.

Available experiments

The first experiment is the Ramsden et al. (2022) methane/ethane shared-state model. It ports the paper-shaped two-gas likelihood to the modern RHIME stack without restoring the obsolete historical loader, sampler, or output system.
