Short summary

This paper is focused on analyzing the coupled behavior between dispersion of reactive pollutants and atmospheric dynamics in different atmospheric conditions using a computational fluid dynamics model. It allows one to provide the selection of the chemical reactions needed that gives the best compromise between accuracy in modeling NO and NO₂ dispersion in the streets and the computational time required. The conclusions can be applied to future studies about modeling air quality in cities.
