The Milky Way Galaxy is literally teeming with exoplanets; thousands of
planets have been discovered, with thousands more planet candidates identified.
Terrestrial-like planets are quite common around other stars, and are expected
to be detected in large numbers in the future. Such planets are the primary
targets in the search for potentially habitable conditions outside the solar
system.
Determining the atmospheric composition of exoplanets is mandatory to
understand their origin and evolution, as atmospheric processes play crucial
roles in many aspects of planetary architecture. In this work we construct and
exploit a 1D radiative transfer model based on the discrete-ordinates method in
plane-parallel geometry. Radiative results are linked to a convective flux that
redistributes energy at any altitude producing atmospheric profiles in
radiative-convective equilibrium. The model has been applied to a large number
(6250) of closely dry synthetic ce{CO2} atmospheres, and the resulting
pressure and thermal profiles have been interpreted in terms of parameter
variability. Although less accurate than 3D general circulation models, not
properly accounting for e.g., clouds and atmospheric and ocean dynamics, 1D
descriptions are computationally inexpensive and retain significant value by
allowing multidimensional parameter sweeps with relative ease.
