Summary: In this research it is proposed a new equation of fractional diffusion-advection which
describes the atmospheric dispersion of contaminants including the formation of secondary
pollutants (sulfur dioxide and sulfate) and their removal processes in the atmosphere. It is
proposed to use the methodology used by Alam and Seinfeld (1981), which uses linear
algebra to decouple the system of equations from the secondary pollutant. To solve the
equations found, it uses the ADMM (Advection Diffusion Multilayer Model) method, which
consists of a semi-analytical solution based on the discretization of the planetary boundary
layer (CLP) in sub-layers, so that the diffusion-advection equation can be solved using the
Laplace transform and the technician GITT in a planetary boundary layer vertically
nonhomogeneous. Simulations proves the influence of dry and wet deposition, including the
order of the derivative, on the concentration of primary and secondary pollutants, representing
step forward in the understanding of the pollutants dispersion in the atmosphere with lower
computational costs due to semi-analytical solution characteristic
