摘要：
A one dimensional radiation fog model with detailed microphysics is presented. Aerosols and cloud droplets are treated in a joint two dimensional size distribution. Radiative fluxes are calculated as functions of the radiative properties of the time dependend particle spectra. Radiative effects are considered in the droplet growth equation. Three numerical sensitivity studies are performed to investigate the impact of the different physico-chemical properties of urban, rural and maritime aerosols on fog formation. Numerical results elucidate that depending on the utilized aerosol models the resulting fog events are completely different. This holds in particular for the times of fog formation and dissipation as well as for the liquid water content and the supersaturations within the fogs.
