The sanitary impact of atmospheric pollution is becoming a major problem of public health in European cities. To estimate citizens exposure and take action accordingly, authorities in charge of monitoring air quality need to know the spatial distribution of pollutants concentration at any time and any place in the city. Several data sets are available from local to regional scale. But either the resolution is too coarse to represent structures of the concentration field at the local scale and models do not cover the area of interest. The method proposed, the “typical fields method”, exploits all available data sets putting emphasis on scales and coherence between information. A typical field is defined as the ensemble of spatial structures of a field for all scales described and for a given meteorological situation.
