Spatial mapping of emissions

The aim of this ‘Spatial emission mapping’ chapter is to provide guidance on how to spatially distribute national air emissions to:

• Support the link between emission data and air quality models that need emissions information at a proper spatial, temporal and sectoral resolution;
• Facilitate countries in (improving) the gridding of their emission inventories of air pollutants under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (CLRTAP) and the EU National Emission reduction Commitment Directive (NECD) including the link to point source emissions (e.g. from EPRTR). 

This chapter provides guidance on compiling spatially explicit emission datasets. It focuses on methods suitable for generating and reporting spatial data required under the LRTAP Convention that are consistent with nationally-reported inventories.
