Abstract

The diffusion equation that describe chemical composition of the atmospheric fine particles (organic and inorganic) is established. This equation describes the main processes involved in the atmospheric evolution of particles: advection, emission, turbulent diffusion, deposition and gas-to-particle conversion (heterogeneous nucleation). Each term in the equation is discussed, and the methodology of implementation on a Lagrangian air quality model is presented, the Lagrangian air quality model has been used successfully for ozone concentration predictions in the Mexico City Metropolitan Area and still is used widely. The model uses a Oper
