Objectives
1) Use LES and laboratory experiments to study the nonlinear coupling among flow dynamics, pollution chemistry and SVOC microphysics in jet plume; 2) Elucidate the characteristic street-level air quality and pollutant removal mechanism in urban environment at micro scale; 3) Improve the current modeling practice for dispersion and source apportionment of vehicular pollutants in the policy innovation perspective.
