Air Quality Simulation of Traffic Related Emissions: Application of Fine-Scaled Dispersion Modelling
This paper focuses on developing and validating the CALMET-CALPUFF modelling system to be ultimately used as a tool for evaluating the potential air quality impacts of transportation plans. Our study is set in the Montreal Metropolitan Area. For this purpose, emissions of Nitrogen Oxides (NOx) were modelled using a transportation and emissions model which accounts for individual trips and vehic...
متن کاملSimulation of Dispersion of Polluted Gases in Atmosphere
A computer program was developed to predict the dispersion of gas pollutant in the atmosphere. This program relies on puff method, and in order to consider the wind shear effects, the program has the ability to consider the complete dynamic and unsteady atmospheric conditions. Plume rise of hot pollutants due to buoyancy effects was also considered. The program has the capacity to perform the r...
متن کاملDispersion bias, dispersion effect, and the aerosol--cloud conundrum
This work examines the influences of relative dispersion (the ratio of the standard deviation to the mean radius of the cloud droplet size distribution) on cloud albedo and cloud radiative forcing, derives an analytical formulation that accounts explicitly for the contribution from droplet concentration and relative dispersion, and presents a new approach to parameterize relative dispersion in ...

متن کاملAerosol bolus dispersion in healthy subjects.
Aerosol bolus dispersion is a physiological test of lungs, which uses monodisperse submicron particles to measure intrapulmonary convective gas mixing. In this study, aerosol bolus dispersion was measured in healthy subjects in order to assess reference values for possible clinical applications, to assess the reproducibility of these values, and to identify physical and physiological factors in...
