Climates, gas mixing ratios, and eddy diffusion profiles for TRAPPIST-1 e, clear-sky, and cloudy aqua planets. Included are data from Earth: the temperature and mixing ratio profiles are from case 62 of the Intercomparison of Radiation Codes in Climate Models (ICRCCM), and the eddy diffusion rate is that retrieved by Massie & Hunten (1981). The temperatures of our modeled atmospheres are somewhat colder than that of modern Earth, but they are still able to maintain surface water. The mixing ratios of trace constituents differ from modern Earth, except CO2.
