The overall objective of SAPPHIRE is to develop and validate a readily transferable common pan-European methodological approach to source apportionment of atmospheric PM and PAH that will be utilised by city authorities. To do so, a series of campaigns monitoring air pollution at 2 locations in each of the following partner cities: Athens, Birmingham, Copenhagen, Helsinki, and Oporto. Data from these campaigns will be used to develop and validate the source apportionment methodology. A technical report describing clearly the source apportionment protocol will be written, and a user friendly customised software package to assist in the data analysis required for source apportionment will be produced. To maximise exploitation of SAPPHIRE outputs, the local authorities of partner cities will critically appraise and review drafts of both the technical report and software package.
