History of Regional Models of Occitania

Application for visualization of modelled data in O3, PM10 and PM2.5 on the Occitanie region. These maps show the annual average concentrations (for NO2, PM10 or PM2.5), or the number of days of exceedance of daily regulatory thresholds (for PM10 and O3). At regional level, these maps represent the exposure of the population in the background in urban, peri-urban or rural areas. At the urban level, the exposure of the population is represented down to the street level. These maps take into account, in particular, the weather conditions of the year and all pollutant emissions in the territory. The data from these exposure maps should be interpreted taking into account the fact that they include a margin of uncertainty.
