Short summary

To accurately represent the population exposure to outdoor concentrations of pollutants of interest to health (NO₂, PM_2.5, black carbon, and ultrafine particles), multi-scale modelling down to the street scale is set up and evaluated using measurements from field campaigns. An exposure scaling factor is defined, allowing regional-scale simulations to be corrected to evaluate population exposure. Urban heterogeneities strongly influence NO₂, black carbon, and ultrafine particles but less strongly PM_2.5.
