 abstract = {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
confirmed by in situ measurements during short intensive and longer-term
campaigns, aerosol optical depth (AOD) measurements from ENVISAT, and
modeling results from PMCAMx and CHIMERE chemistry transport models.
While advection of sulfate is well documented for other megacities,
there was surprisingly high contribution from long-range transport for
both nitrate and organic aerosol. The origin of organic PM was
investigated by comprehensive analysis of aerosol mass spectrometer
(AMS), radiocarbon and tracer measurements during two intensive
campaigns. Primary fossil fuel combustion emissions constituted less
than 20% in winter and 40% in summer of carbonaceous fine PM,
unexpectedly small for a megacity. Cooking activities and, during
winter, residential wood burning are the major primary organic PM
sources. This analysis suggests that the major part of secondary organic
aerosol is of modern origin, i.e., from biogenic precursors and from
wood burning. Black carbon concentrations are on the lower end of values
encountered in megacities worldwide, but still represent an issue for
air quality. These comparatively low air pollution levels are due to a
combination of low emissions per inhabitant, flat terrain, and a
meteorology that is in general not conducive to local pollution
build-up. This revised picture of a megacity only being partially
responsible for its own average and peak PM levels has important
implications for air pollution regulation policies.},
