Ensemble operational air quality assessments in Europe - Improving modeling platforms with statistical analysis
MACC-II - Monitoring Atmospheric Composition and Climate - is the current COPERNICUS (previously known as GMES Global Monitoring for Environment and Security) - Atmosphere Service throughout Europe. For regional air quality, seven regional modeling teams combine state-of-the-art atmospheric modeling with Earth observation data assimilation. All mod...
Simulation of size-segregated aerosol chemical composition over northern Italy in clear sky and wind calm conditions
The present article compares the outputs of the 3-D regional chemistry-transport model (CTM) CHIMERE against observations of the size-resolved aerosol chemical composition over northern Italy in clear sky and wind calm conditions. Two 4-day intensive field campaigns were carried out in July 2007 and February 2008 at three sites (urban, rural and mo...
Evaluation of regional climate simulations for air quality modelling purposes
Published in Climate Dynamics
In order to evaluate the future potential benefits of emission regulation on regional air quality, while taking into account the effects of climate change, off-line air quality projection simulations are driven using weather forcing taken from regional climate models. These regional models are themselves driven by simulations carried out using glob...

A statistical approach to improve air quality forecasts in the PREV'AIR system
Since 2003, the national PREV'AIR system (www.prevair.org) has been delivering daily air quality forecasts of atmospheric pollutants (O3, NO2, PM10, PM2.5) over Europe and France. Those products are based on chemistry-transport modeling and in particular on the outputs from CHIMERE model. Analysed air quality maps of the previous day are also produ...
Impacts of future air pollution mitigation strategies on the aerosol direct radiative forcing over Europe
Projections of aerosol emissions for 2030 have been recently generated and implemented in a comprehensive chemistry-transport model to analyse the future evolution of the aerosol radiative forcing over Europe. In this study, numerical developments based on an off-line coupling between the regional chemistry-transport model CHIMERE (extended by an a...
Impact of the total aerosols solar extinction on photochemical pollution during the heat wave of summer 2003 over Wester...
By controlling the abundance of photochemical pollutants, photolytic reactions plays a critical role in atmospheric chemistry. However, aerosols may alter photolysis rates by interacting with short-wave solar radiation, which in turn can modify associated concentrations of some gaseous compounds (ozone, nitrogen dioxide) and secondary aerosols spec...
A new statistical approach to improve air quality forecasts in the framework of CITEAIR and PREV'AIR
The PREV'AIR system (http://www.prevair.org) was implemented in 2003 with the aim of generating and publishing daily air quality forecasts and maps resulting from numerical simulations on different spatial scales. The operational air quality monitoring system has been constantly evaluated against measurements and improved with geo statistical analy...
