Characterization method
Atmospheric Retrieval
The statistical machinery that turns a spectrum into numbers: models of an atmosphere are compared against the data, usually with Bayesian inference, to find the mix of gases, temperatures, and clouds that best explains it — along with honest uncertainties. Retrieval is how a wiggly spectrum becomes a measured abundance.
