Ground truths and disk-integrated MIR spectra for the NP, SP, and EqC Earth views introduced in Section 2.3.2. Solid lines indicate the data for January and dashed lines represent the month July. Color-shaded areas indicate the uncertainties on the data. Left column: Ground truth P−T profiles. Center column: Ground truth abundance profiles for CO2,O3,CH4, and H2O. Right column: R = 50 disk-integrated monthly averaged Earth spectra. The color-shaded areas indicate the S/N = 10 LIFEsim-noise level. -- astro-ph.EP

Pursuing Truth: Improving Retrievals on Mid-Infrared Exo-Earth Spectra with Physically Motivated Water Abundance Profiles and Cloud Models

by Keith CowingAugust 20, 2024August 20, 2024

Atmospheric retrievals are widely used to constrain exoplanet properties from observed spectra. We investigate how the common nonphysical retrieval assumptions of vertically constant molecule abundances and cloud-free atmospheres affect our […]
