Abstract The study represents the first assessment of OCS contributions to ozone in the Gulf of Mexico. Two ozone episodes (July 20-August 6, 1988, and July 24-August 1, 1990), which had onshore winds for transporting OCS-derived ozone to onshore areas, were selected for analysis. The model's onshore emissions input consisted of the 1985 National Acid Precipitation and Assessment inventory, the Biogenic Emissions Inventory System, and mobile sources from the 1986 vehicle traveled data adjusted to 1988. The model's performance evaluation reveals an average normalized gross error of 31%, while the paired accuracy of peaks averaged 22.8%. The results of the assessment suggest that a similar study using an improved emissions database and a photochemical model with finer spatial resolution to gain a better understanding of OCS contributions is desirable.
