Climates and spectra of Earth-like planets

Earth is our only known example of a habitable or inhabited planet. Our ability to characterize Earth-like exoplanets is very limited with current instruments, so numerical simulations are an essential tool for understanding their climates. In this presentation, I will use 3D climate simulations to discuss some key factors that contribute to a terrestrial planet's climate, as well as the possible impacts of these factors on observations.
