Receptor modeling refers to a set of procedures for identifying and quantifying the sources of ambient air pollution impacting a monitoring site (receptor) primarily on the basis of chemical species concentration measurements at the receptor. In its purest form receptor modeling requires neither emissions inventory information nor meteorological data for its implementation.The very large quantities of volatile organic compound (VOC) ambient data that are beginning to be generated in the Photochemical Assessment Monitoring Stations (PAMS) network offer an unusual opportunity for receptor modeling applications. The authors will discuss primarily the Chemical Mass Balance (CMB) method of receptor modeling, illustrating it with recent results from analysis of the EPA 1990 Atlanta Ozone Precursor Study. The design of that study has many similarities (species measured, number of stations, etc.) to what is being implemented in PAMS, and thus provides a first assessment of the receptor modeling possibilities with PAMS data.
