Short summary
A new method is presented for allocating the anthropogenic part of a pollutant concentration to the sources responsible. The method requires integrating sensitivity coefficients over a range of emissions defined by an emission-control strategy. A simplified photochemical model is used to evaluate options for the numerical integration and the dependence of the source contributions on the control strategy. Results are presented for ozone, formaldehyde, nitrogen dioxide, and nitric acid.
