Vertical distribution of SO2 in upper cloud layer of Venus and Origin of U.V.-absorption

Vertical distribution of SO2 in upper cloud layer of Venus and Origin of U.V.-absorption

It is shown that the decline of the spherical albedo of Venus toward the ultraviolet can be explained by the presence of two absorbing agents: (1) SO2, for which the abundance is 10 to the 11th/cu cm at a height of 68 km and the scale height is about 1 km; (2) some unknown aerosol absorbent, possibl...

Zusammenfassung:It is shown that the decline of the spherical albedo of Venus toward the ultraviolet can be explained by the presence of two absorbing agents: (1) SO2, for which the abundance is 10 to the 11th/cu cm at a height of 68 km and the scale height is about 1 km; (2) some unknown aerosol absorbent, possibly a 1% FeCl3 admixture in a sulfuric acid concentrated solution. A mechanism of aerosol formation is proposed.
