Climate And Atmospheric Models Of Rocky Planets: Habitability And Observational Properties — Habitability map on the semi-major orbital axis vs eccentricity plane (color-code in the lower bar; the habitability criterion is the ”complex” habitability as defined in Silva et al. (2017b). Those solutions admitting climate warm-snowball bistability are shown with filled circles. Their color-code in the right bar gives the snowball probability. Most bistable and habitable solutions are found within the same parameter range. See Murante et al. (2020) for more details. — astro-ph.EP

The quest for atmospheric spectral signatures that may witness biological activity in exoplanets is focused on rocky planets.

The best targets for future, challenging spectroscopic observations will be selected among potentially habitable planets. Surface habitability can be quantified and explored with climate and atmospheric models according to temperature-based criteria.

The conceptual, modellistic, technological and interpretative complexity of the problem requires to develop flexible climate and atmospheric models suited for a comprehensive exploration of observationally unconstrained parameters, and to simulate and interpret definitely non-terrestrial conditions.

We present a summary and preliminary results on the work we are performing on multi-parametric explorations of the habitability and observational properties of rocky planets.
