The smog chamber facility of the University of North Carolina was used to provide experimental data for developing and testing kinetic mechanisms of photochemical smog formation. In this study, 128 pairs of experiments were performed using NOx and various hydrocarbons and hydrocarbon mixtures. The experiments performed during this three-year project have been added to the existing UNC data base for model testing, bringing the total number of pairs of experiments to 346. This report presents an organizational scheme for these 346 experiments. This scheme enables users of the data to readily access specific portions of the data set. The report also contains guidance to modelers about which experiments should be simulated to test various aspects of the models and what order the experiments should be simulated in.
