EOS-ESTM: A flexible climate model for habitable exoplanets

ABSTRACT Rocky planets with temperate conditions provide the best chance for discovering habitable worlds and life outside Solar system. In last decades, new instrumental facilities large observational campaigns have been driven by quest worlds. Climate models aimed at studying habitability of rocky are essential tools to pay off these technological endeavours. this context, we present eos-estm, a fast flexible model exploring impact on multiple climate factors, including those unconstrained observations. eos-estm is built estm, seasonal-latitudinal energy balance featuring an advanced treatment meridional vertical transport. The novel features include: (1) parametrizations simulating oceans, land, ice, clouds as function temperature stellar zenith distance (2) procedure (eos) calculating radiative transfer in atmospheres terrestrial non-terrestrial compositions illuminated solar- non-solar-type stars. By feeding Earth’s stellar, orbital, planetary parameters, derive reference that satisfies number constraints Validation tests yield predictions line comparable results obtained hierarchy models. application maximum greenhouse demonstrates possibility tracking snowball transition outer edge HZ variety paving road multiparametric studies HZ.
