Abstract
Two approaches for identification of source locations and preferred transport pathways of atmospheric particulate trace elements and aerosol species are investigated, namely, versions of the potential source contribution function method (PSCF) and the concentration field method (CF). Both methods are based on combining chemical data with calculated air parcel backward trajectories. The two methods are applied to four multi-species multi-annual concentration time series measured at sites in Finland, Norway, and Israel. A non-parametric bootstrap technique is used to estimate the statistical significance of the calculated PSCF values. It is found that the methods agree well with each other and correctly identify known emission sources. Examples of applying the methods are presented, mainly for the site in Finland.
