Abstract
The highest concentrations of ozone in each season were associated with transport off the North American continent; the lowest concentrations were during low-level maritime transport around the Bermuda high. Using the vertical component of the isentropic trajectories, we also showed that the most extreme concentrations of ozone occurred with rapidly descending air from mid tropospheric levels. This pattern was most pronounced in April and May when more than 50% of the O3 variability was related to transport differences. We conclude that this relatively remote marine site, which normally experienced low maritime ozone levels (~30 parts per billion by volume (ppbv)), periodically entrained dry, ozone-rich (~55 ppbv) midtropospheric air in association with strong subsidence in high pressure behind spring low-pressure systems. -from Authors
