Complex Area Sources

Complex Area Sources represent areas (arbitrary polygons or regular grids) with their total (usually tier1) emissions, that can each contain any number of individual point, ares or line sources. Individual emisison sources within a Comples Area Source are substracted from the overall Complex source emissions, subject to the remaining total ≥ 0.

Typical examples would be administrative units like municipalities or counties, with their emissions estimated by resident population, or gegular emission grids such as the European EMEP data set.

EMEP emission data set

The European Monitoring and Evaluation Programme (EMEP) is a scientifically based and policy driven programme under the Convention on Long-range Transboundary Air Pollution (CLRTAP) for international co-operation to solve transboundary air pollution problems. See the EMP home page: http://www.emep.int/index.html


The Convention on Long-range Transboundary Air Pollution (LRTAP), signed in 1979, is one of the central means for protection of our environment. It establishes a broad framework for co-operative action on reducing the impact of air pollution and sets up a process for negotiating concrete measures to control emissions of air pollutants through legally binding protocols. In this process, the main objective of the EMEP programme (Co-operative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe) is to regularly provide governments and subsidiary bodies under the LRTAP Convention with qualified scientific information to support the development and further evaluation of the international protocols on emission reductions negotiated within the Convention. for details of the data set and the underlying spatial grid, see: http://www.emep.int/mscw/Grid/emep_grid.html

A complex Area Source object consists of

  • the usual objectheader, name, META data, owner/modification date;
  • save, delete, and copy buttons;
  • A button "Gmaps" that will show the source boundaries over a live, interactive Google map;
  • a table with Source Attributes, coordinates, and country coding;
  • the emission data table for NOx, SOx, PM2.5, PM10, CO, VOC and NH3 for 11 setors (Energy and transformation industries, Non-industrial combustion plants, Combustion in manufacturing industry, Production processes, Fossil fuels and geothermal energy, Solvent use and other product use, Road transport, Other mobile sources and machinery, Waste treatment and disposal, Agriculture, Other sources and sinks), total emissions and split into individual sources and "background", as well as a table of the individual source classes that links to lists and eventually the individual emision sources considered within the Complex Area Source.
