The European Directive on ambient air quality and cleaner air for Europe (2008/50/EC; AQD) identifiesdifferent uses for modelling: Assessment, planning, forecast and source apportionment (SA). Thisdocument addresses source apportionment modelling and specifies performance tests to check whethergiven criteria for receptor oriented source apportionment models (RM) are met. The scope of the testsset out in this document is the performance assessment of SA of particulate matter using RM in thecontext of the European Directives 2004/107/EC and AQD, including the Commission ImplementingDecision 2011/850/EU of 12 December 2011. The application of RM does not quantify the spatial originof particulate matter; hence, this document does not test spatial SA.
