Spatial inter-comparison of Top-down emission inventories in European urban areas

This paper presents an inter-comparison of the main Top-down emission inventories currently used for air quality modelling studies at the European level. The comparison is developed for eleven European cities and compares the distribution of emissions of NOx, SOx, VOC and PPM2.5 from the road transport, residential combustion and industry sectors. The proposed analysis shows that substantial differences in terms of total emissions, sectorial emission shares and spatial distribution exist between the datasets at the urban level. The possible reasons in terms of downscaling approaches and choice of spatial proxies are analyzed and some recommendations are provided for each inventory with the aim of working towards the harmonization of spatial downscaling and proxy calibration, in particular for policy purposes. The proposed methodology may be useful for the development of consistent and harmonized European-wide inventories with the aim of reducing the uncertainties in air quality modeling activities.
