Urban air pollution—a diffusion equation model

Mathematical Biosciences, 1975
Abstract A mathematical model for the occurrence and diffusive propagation of air pollution in an urban air space is proposed. Using a Green's function of the proposed diffusion equation and a Poissonian emission process, a statistical analysis of the resulting density of air pollution is made.

Diffusion for Diffusion: A versatile multiphysics fields refinement framework in pollutants transportation

Water Research
Refining coupled multiphysics fields in pollutant transport from sparse measurements is critical for environmental risk assessment and industrial pollution mitigation. However, existing numerical solvers and machine learning architectures exhibit inherent limitations in computational efficiency, generalizability, and predicting accuracy.

Guide to Local Diffusion of Air Pollutants

1971
Abstract : The report is intended as a guide on local air pollution for forecasters who have had no prior experience with diffusion. Certain fundamentals of micormeteorology and diffusion in the lower layers are expounded and their relatio to the determination of air pollutant dispersion and concentration amounts is explained.
