A radiative-convective model for lava planet atmospheres

Overview

A numerical model for the atmospheres of hot rocky (exo)planets. AGNI's primary purpose is to simulate the evolving atmospheres of magma ocean planets, while ensuring that radiative-convective equilibrium is maintained throughout the atmosphere.

AGNI models correlated-k radiative transfer including shortwave irradiation from the star, surface emission, gaseous absorption, Rayleigh scattering, parameterised clouds, and CIA. Mixing length theory is used to model convection. Together, energy transport processes allow for an energy-conserving calculation of the atmosphere's temperature profile.

Consult the AGNI documentation for information about the model.
