TL;DR: In this article, atmospheric inversion is used to adjust the daily to monthly budget of fossil fuel CO2 emissions of the Paris urban area from the prior estimates established by the Airparif local air quality agency.

TL;DR: In this paper, measurements of the mole fraction of the CO2 and its isotopes were performed in Paris during the MEGAPOLI winter campaign (January-February 2010) to identify the relative contributions of 77% CO2 from fossil fuel consumption and 23% from biospheric CO2 (CO2 from the use of bio fuels and from human and plant respiration: CO2bio).

TL;DR: In this article, a 10-year model simulation over the greater Paris (France) area at 4 km resolution and anthropogenic emissions from a 1 km resolution bottom-up inventory was used to estimate the sensitivity of modeled ozone and PM2.5 concentrations to different potentially influential factors with a particular interest over the urban areas.

TL;DR: In this paper, the CHIMERE air quality model was used to model ozone and PM 2.5 concentrations over the city of Paris. But the results showed that ozone formation over Paris at the current urban-scale study is driven by volatile organic compound (VOC)-limited chemistry, whereas at the regional-scale ozone formation occurs under NO x -sensitive conditions.

TL;DR: In this article, an approach based on airborne measurements across the Paris, France, plume was developed in order to evaluate BC and NO x emissions at the scale of a whole agglomeration.
