Research output: Contribution to journalArticlepeer-review


A model of Titan's aerosol is presented which allows the particle size to vary with height. The model assumes a refractive index appropriate to an ethylene polymer and a mass flux independent of height equal to the value derived from laboratory measurements. The free parameters of the model are determined by fitting to the observed geometric albedo at 4000 and 6000 Å. A methane spectrum is derived which is in excellent agreement with observations. An aerosol optical depth of ∼5 is found in the visible, with the particle radius varying from 0.01 to 8 μm. The presence of an optically thick methane cloud at the temperature minimum is indicated.
