Investigation of the glory in the space of x_eff and v_eff parameters. Left and right panels represent calculations for refractive indices n_r = 1.44 and 1.33, respectively. Panels A)–B) are the positions of the local minimum within the glory, α_m, and F₁₁(α_M)/F₁₁(α_m) is the associated contrast based on the scattering phase function. Panels C)–F) incorporate the multiple scattering calculations for the prescribed Venus-based atmospheres. Panels C)–D) are for semi-infinite atmospheres, whereas E)–F) are for atmospheres of finite optical thickness equal to 5 above a black surface. All calculations assume a uniform atmosphere of the specified unimodal size distribution of scattering droplets. In panels C)–F), only configurations leading to Φ(α_M)/Φ(α_m) > 1 are shown. At λ = 0.445 μm, x_eff for Venus and Earth (average effective radius ~6 μm) liquid clouds are ~14 and 85, respectively.
