This report is a companion document to PB-278 142, Uses, Limitations and Technical Basis of Procedures for Quantifying Relationships Between Photochemical Oxidants and Precursors. Particular emphasis is placed on providing additional background documentation on the development of the Empirical Kinetic Modeling Approach (EKMA). Specifically, the report describes: (1) procedures for estimating the prevailing 6-9 a.m. NMHC/NOx ratio for a city, (2) the use of default NMHC/NOx ratios, (3) procedures for estimating transported ozone concentrations and (4) the results of kinetic model simulations for a range of meteorological conditions and precursor levels. Topics which have general significance in a number of different procedures for quantifying ozone-precursor relationships include the prevailing background concentration of ozone and the greater importance of transported ozone as opposed to transported precursors.
