The rapid urbanization and growing number of megacities and urban complexes requires
new types of research and services that make best use of science and available technology …

Nitrogen dioxide (NO2) is a regulated air pollutant that is of particular concern in many cities,
where concentrations are high. Emissions of nitrogen oxides to the atmosphere lead to the …

Accelerating growth of urban populations, especially in developing countries, has become a
driving force of human development. Crowded cities are centres of creativity and economic …

Satellite observations of the total column dry‐air CO2 (XCO2) are expected to support the
quantification and monitoring of fossil fuel CO2 (ffCO2) emissions from urban areas. We …

Megacities and other major population centres (MPCs) worldwide are major sources of air
pollution, both locally as well as downwind. The overall assessment and prediction of the …

As cities are growing in size and complexity, the estimation of air pollution exposure requires
a detailed spatial representation of air pollution levels, rather than homogenous fields …

Simulations with the chemistry transport model CHIMERE are compared to measurements
performed during the MEGAPOLI (Megacities: Emissions, urban, regional and Global …

This study shows the capabilities of a benchmarking system to identify inconsistencies in
emission inventories, and to evaluate the reason behind discrepancies as a mean to …

Secondary inorganic compounds represent a major fraction of fine aerosol in the Paris
megacity. The thermodynamics behind their formation is now relatively well constrained but …

This study examines the role of horizontal grid resolution on the performance of the regional
three dimensional chemical transport model (CTM) PMCAMx. Two cases were investigated …
