A multivariate statistical evaluation technique, non-linear mapping, is proposed to extract information from a multielement microbeam proton-induced X-ray emission data set. Individual aerosol particles, collected in the North Sea troposphere, were classified according to their composition. Several groups of particles were identified and suggestions are made for their sources.
