(author), Perrussel, O. (author), Schwarzenboeck, A. (author), Sciare, J. (author), Wiedensohler, A. (author), Zhang, Q.J. (author)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...article 2015

(author)A detailed characterization of air quality in the megacity of Paris (France) during two 1-month intensive campaigns and from additional 1-year observations revealed that about 70 % of the urban background fine particulate matter (PM) is transported on average into the megacity from upwind regions. This dominant influence of regional sources was...article 2015
