Introduction to and Application of Receptor Models
Philip K. Hopke, University of Rochester, USA
Abstract: This tutorial will present the underlying chemical basis for distinct profiles for the different types of emission sources and how these differences in profiles then permit the application of receptor models. The conceptual framework of receptor models, a mass balance approach, will be described. The resulting mathematical approaches can be then implemented depending on what a priori information is available. The use of ancillary data such as meteorology and back trajectories will be introduced. Applications of several types of models to various particle composition problems will be described with an emphasis on the practical use of Positive Matrix Factorization for both elemental and organic species data.
