A parametric study of Io's thermophysical surface properties and subsequent numerical atmospheric simulations based on the best fit parameters

► Io's surface thermophysical properties are constrained by a parametric study. ► Best fit albedos are αF ≈ 0.55 and αNF ≈ 0.49. ► Best fit thermal inertias are ΓF ≈ 200 J m−2 K−1 s−1/2 and ΓNF ≈ 20 J m−2 K−1 s−1/2. ► Atmospheric structure of the sub-jovian side is strongly affected by jovian eclipse. ► Sub-jovian/anti-jovian hemisphere asymmetry is likely partially caused by eclipse.
