Differences in Water Vapor Radiative Transfer Among 1d Models Can Significantly Affect the Inner Edge of the Habitable Zone

Abstract: An accurate estimate of the inner edge of the habitable zone is critical for determining which exoplanets are potentially habitable and for designing future telescopes to observe them. Here, we explore differences in estimating the inner edge among seven one-dimensional radiative transfer models: two line-by-line codes (SMART and LBLRTM) as well as five band codes (CAM3, CAM4_Wolf, LMDG, SBDART, and AM2) that are currently being used in global climate models. We compare radiative fluxes and spectra in clear-sk… Show more

“…Dashed lines and triangles are used to mark constraints on the outer edge of the habitable zone. 1 Used for simulations into and out of snowball states, see Shields et al (2013) 2 Used for simulations of moist greenhouse states, see Wolf & Toon (2015) 3 See Yang et al (2016) for a comparison of these two codes. Table 2: Global and annual mean quantities from control simulations using the warm configuration, which includes ocean heat transport identical to the modern Earth.…”

“…Here numerical improvements to the convection scheme allow us to simulate much hotter temperatures, and define a true inner edge of the habitable zone by water-loss from moist greenhouse atmospheres. Note also that the position of the inner edge determined by Yang et al (2014) and Wolf & Toon (2015) is also affected by differing properties of the radiative transfer model used (see Yang et al 2016). …”

“…The main difference between these two studies lies in the spectral databases and continua used to derive the radiative fluxes in the planetary atmosphere. It has been shown that especially the treatment of the radiative properties of water vapor can lead to different results at the inner edge of the HZ (Yang et al 2016). Here we used yet another spectral database (HITEMP1995) and continuum assumptions different from those of Kasting et al (1993b) and Kopparapu et al (2013).…”

“…It would be prudent to test any fast radiation code that one planned to use against a well-trusted line-byline code across the parameter space of interest (e.g. Goldblatt et al, 2009b;Wolf, 2013;Yang et al, 2016); however, doing this requires both the specialist knowledge in radiative transfer, the local availability of such a model and a lot of time and energy. All of these can be hard to come by.…”
