Venus phase curve in the B band and scattering particle phase functions at λ = 0.445 μm. A) Symbols stand for the measured phase curve. Black and red are ground- and space measurements. The solid blue line is our modelled phase curve at λ = 0.445 μm. B) Scattering phase functions for Rayleigh particles, mode-1 and mode-2 droplets, and a combined Rayleigh/mode-1/mode-2 particle. C) Phase curve for α ≥ 130°. Exploration of the model sensitivity to H (=2, purple; 4, cyan) and Δ (=4.7H, dashed; ∞, dashed-dotted). D) Phase curve for α ≤ 50°.
