Supplementary Data supporting "TEXAS: A proxy system model for TEX86 paleothermometry"

Calibration posteriors, the GDGT training database, and the temperature reconstructions supporting a paper entitled “TEXAS: A proxy system model for TEX86 paleothermometry” at AGU Paleoceanography & Paleoclimatology. The TEXAS PyPI (texas-psm) package is archived on a parallel Zenodo repository (10.5281/zenodo.19671664). Item IDDescription Posteriors_fwdThe nine forward Bayesian calibration fits: the full multivariate T₀-shift model (SST and Thermo-T), its GDGT-2/3-only, NO₃-only, and temperature-only variants, and the culture+mesocosm stage-1 fit.

Used by Figs. 10–13.Files: 40 files, one per site × model configuration (nitrate-scenario variants for the sites that need them, two full-posterior-draws files for Co1010 and ODP1259) — see this record's own file listing for exact names.Folder on the GitHub/TEXAS repo: posteriors/invT/paleo/ Data_trainingThe combined GDGT culture, mesocosm, and coretop training database (raw and screened/gridded), the CMEMS nitrate-uncertainty field, and the coretop site table.
