Aerosol source apportionment with Positive Matrix Factorisation of both particle number size distribution and chemical composition

Abstract

The study applied Positive Matrix Factorisation (PMF) model to number size distribution data, to apportion the aerosol particle sources over size range of 14nm-10µm, to investigate the relationship between size distribution and composition data.
