Posterior draws from 14 hierarchical Bayesian leaf-wax-to-precipitation calibration models, fit in Stan on the frozen calibration run c2_run_20260626 (n = 1128 observations; Bradley 2026, Communications Earth and Environment). Each file is a posterior::draws_df with 1000 stratified draws across 8 MCMC chains. Spatial models include 125 per-knot latent z values on a Fibonacci sphere lattice. Used by the leafwax R package as the full-resolution backing data; the package ships a 100-draw fixture and downloads the full posteriors from this archive on first use. Supersedes the v1.x deposit (v10 / n = 1129 lineage).
