Reflectance phase curves for observer inclinations of (from top to second from bottom) 90°, 60°, and 30° and the emission phase curve for an observer inclination of 60° (bottom) for the tidally-locked Earth-like case. Phase curves are shown for wavelength ranges closely matching those of Turbet et al. (2016) for comparison. Clear-sky fluxes are represented in dashed lines to highlight the role of clouds, which generally increase the shortwave planetary flux but have much more subtle effects for the longwave flux. The emission phase curves show very little variation with observer inclination, hence we only show the i = 60° case for brevity. We note that a very small flux ratio is found in the 0.28−0.30 μm region, due to ozone absorption.
