Abstract |
A material balance model and an inversion technique was developed that appear to produce reasonable estimates of the contribution of different emission sources in the Los Angeles atmosphere. Different sources exhibit very characteristic diurnal and daily patterns. The automobile exhaust contribution to the hydrocarbon burden on weekdays was found to be different from that on weekends. Estimates of the loss of reactive compounds such as ethylene and propylene were made and these compare favorably with smog chamber data. |
