Transboundary pollution and local emission impact in tropospheric ozone accumulation processes: control strategy modelling assessment

Ozone production and accumulation in troposphere phere are nonlinear processes, forced by precursor emissions, either from anthropogenic or natural sources, and solar radiation. Furthermore, photochemical pollution can be locally produced or can due to transboundary processes. Because of the problem complexity, mathematical model represents a useful tool for regional Authorities to implement efficient air quality control strategies. In this paper the factor separation approach has been formalized and applied to assess the relative and absolute boundary condition and local emission impact in tropospheric ozone accumulation processes over Northern Italy. The proposed technique processes the simulations of a 3D photochemical modelling system.
