Historical reconstruction of background air pollution over France for 2000-2015

This datasets covers 16-year of air pollution concentrations and air quality indicators over France. Using a kriging method that combines background measurements of air quality and modeling with the Chemistry Transport Model CHIMERE, hourly concentrations of NO2, O3, PM10 and PM2.5 are produced with a spatial resolution about 4 kilometers. Regulatory indicators (annual average, SOMO35, AOT40 etc…) are also calculated from these data. Regulatory indicators are given at the regional, departmental and municipal levels as csv files for the different years. They are also provided at the model grid resolution on a netcdf format.
