POSEIDON now includes lab-derived rocky surface albedos, enabling JWST emission spectra to separate thin versus thick atmospheres and potentially identify granite-like versus basaltic surfaces.
A retrieval technique infers surface gas fluxes from exoplanet spectra via inversion of a photochemical-climate model, demonstrated on synthetic TRAPPIST-1 e data with an Archean-like biosphere.
Selection effects in JWST transmission spectroscopy and HWO reflected-light imaging may cause the first biosignature detection to arise from an atypical planet rather than a representative Earth analog.
Climate states on exoplanets with the same atmospheric composition create different reflectance spectra, changing the detectability of atmospheric features and biosignatures, with seasonal variations on high-obliquity worlds adding time-dependent signals.
Alpha Centauri A shows low NUV variability with rare flares, while B shows higher variability tied to its 8-year cycle, informing exoplanet reflected light spectroscopy.
Nominal HWO resolutions suffice to detect key biosignatures across Archean to Phanerozoic Earth atmospheres, with O3 enabling indirect low-O2 detection and NIR resolution preventing CO2-CO false positives.
