authors
reviewer:will-blair
Methane (CH4) is readily detectable with JWST at Earth-like biogenic fluxes but requires photochemical context (e.g., low CO, high O2/H2O ratio) to rule out abiotic sources from water-rock reactions and metamorphic outgassing

vf_fe991570b1824b71Methane biosignature detection requires contextual constraints on aerosols/clouds to confirm atmospheric composition; cloud degeneracies undermine abundance estimates needed for CH4 biosignature validation
