Characterizing the habitability and climate of temperate, Earth-sized exoplanets using a hierarchy of numerical climate models

Abstract
The last 3 years have been incredibly fruitful in discoveries of nearby temperate, Earth-sized exoplanets, with the detection of Proxima b - the closest exoplanet from us - and the seven planets of the TRAPPIST-1 system. These are the best - potentially habitable - targets we have for a future characterization by either transit spectroscopy, direct imaging, or thermal phase curves with the upcoming James Webb Space Telescope and the extremely large ground-based telescopes.

I will discuss how climate models, ranging from 1-D radiative-convective models, to 3-D Global Climate Models and even 3-D Cloud Resolving Models, can be used to study the habitability, climate and observability of these nearby temperate, Earth-sized exoplanets. Specifically, I will show some examples of how these numerical climate models can be used to invent observational predictions to learn more about temperate, Earth-sized planets.
