The data base outlined in this volume is the result of a vehicle emissions test program conducted in the high altitude environment of the Denver, Colorado area during the period from August, 1973 to November, 1974. The test program, designed to investigate several emission control strategies within the state of Colorado. A sample of 300 light duty vehicles, selected to duplicate as closely as possible Colorado registration distributions by make and model year, was assembled. Data were obtained in several categories for carbon monoxide and nitrogen oxides. The results appear in tabular form.
