Short summary
A new approach coupling aerosol chemical and optical properties in one source apportionment study is proposed. Besides a more robust identification of sources, it was possible to retrieve a source-specific absorption Ångström exponent and a mass absorption cross section at different wavelengths as well as optical apportionment. This piece of information can be very useful for formulating strategies for pollutant abatement to improve air quality and to face climate challenges.
