Moment Dynamics Equations of the Modal Aerosol Dynamics was extended to simulate the Brownian coagulation of multimodal aerosol covering full size ranges and arbitrary fractal dimensions. The model was referred to as Modal Aerosol Dynamics model for multiple Modes and fractal Shapes (MADMS). However, the modal methods including MADMS had a critical limitation in application that a mode is always described by a single size distribution function. In order to describe a complex shape of size distribution, the modes of MADMS are discretized into bins in size dimension. The new approach is referred to as Modal Bin Hybrid Model (MBHM). As a performance evaluation of MBHM, one box model calculations were performed to simulate the rapid, simultaneous and non-equilibrium evolution processes of atmospheric aerosols through new particle formation, condensation and coagulation from 1 nm to sub-micron meter ranges.
