Data Files Description

This 2D energy balance climate model, named PlaHab, is the first such model to simulate N2-CO2-H2O-H2 atmospheres of both rapidly and slowly rotating terrestrial planets in our solar system and beyond (exoplanets). I have recently used it to model Earth, Mars, and tidally-locked exoplanets, including TRAPPIST-1e and Proxima Centauri b (Ramirez 2024). Most results are consistent with those of 3D GCMs. However, PlaHab has the additional advantage of speed. Thus, it combines some of the detail and complexity of 3D models with the speed and ease-of-use of simpler ones, facilitating the exploration of much larger parameter space. This makes it very efficient to quickly check model results against large suites of observational data.

Abstract

Energy balance models (EBMs), alongside radiative–convective climate models and global climate models (GCMs), are useful tools for simulating planetary climates. Historically, planetary and exoplanetary EBMs have nearly all been 1D latitudinally dependent models with no longitudinal dependence. PlaHab is the first EBM that can simulate N2–CO2–H2O–H2 atmospheres of both rapidly and synchronously rotating planets, including Mars, Earth, and exoplanets located within their circumstellar habitable zones. PlaHab includes physics for both water and CO2 condensation. Regional topography can be incorporated. Overall, EBM results are consistent with those of other 1D and 3D models, although minor differences among all models continue to be related to the treatment of clouds and other known differences between EBMs and GCMs, including heat transport parameterizations. Although 2D EBMs are a relatively new entry in the study of planetary/exoplanetary climates, their ease of use, speed, flexibility, wide applicability, and greater complexity (relative to 1D models) may indicate an ideal combination for the modeling of planetary and exoplanetary atmospheres alike.
