This measurement was supported by filter sampling, SMPS and trace gases concentrations. Raw data obtained from AMS at 1 minute time resolution were trimmed and averaged over 30 minute intervals. Subsequently, the data included the matrix of concentrations of each mass (m/z, mass to charge ratio) over time and the corresponding error matrix were exported for the source apportionment analysis. Data were analyzed using SoFi software, which uses the Multi‐linear engine (ME‐2) (Paatero, 1999) based on the principle of positive matrix factorization (PMF). The advantage of this approach is that the user may, on the basis of partial knowledge of one or more aerosol sources, limit the number of possible solutions and thus refine the result of the model.
