Evaluating BC and NOx emission inventories for the Paris region from MEGAPOLI aircraft measurements

High uncertainties affect black carbon (BC) emissions, and, despite its important impact on air pollution and climate, very few BC emissions evaluations are found in the literature. This paper presents a novel approach, based on airborne measurements across the Paris, France, plume, developed in order to evaluate BC and NO<inf>x</inf> emissions...

Quantification of the urban air pollution increment and its dependency on the use of down-scaled and bottom-up city emission inventories

The impact of large cities on air pollution levels usually is determined with models driven by so-called downscaled emission inventories. This implies that annual emissions of air pollutants at the national scale are spatially distributed over a grid using proxy data like population density. These inventories are frequently used for regional air...
