A six weeks intercomparison campaign was organized in Marseille from the 25th of January to the 2nd of March 2011 in an urban background site. The objectives of this field campaign were to intercompare airborne measurements (mass, chemical composition) and source apportionment
methodologies in order to converge towards a common methodology between the 5 harbours (Barcelona, Genoa, Marseille, Thessaloniki and Venice) involved in the project.
Results of the intercomparison campaign were elaborated by the partnership and collected in a final report
