Ozone measurements from a global network of surface sites
From a network of surface ozone monitoring sites distributed primarily over the Atlantic and Pacific Oceans, the seasonal, day-to-day, and diurnal patterns are delineated. At most of the NH (Northern Hemisphere) sites there is a spring maximum and late summer or autumn minimum. At Barrow, AK (70 deg...

From a network of surface ozone monitoring sites distributed primarily over the Atlantic and Pacific Oceans, the seasonal, day-to-day, and diurnal patterns are delineated. At most of the NH (Northern Hemisphere) sites there is a spring maximum and late summer or autumn minimum. At Barrow, AK (70 deg N) and Barbados (14 deg N), however, there is a winter maximum, but the mechanisms producing the maximum are quite different. All the sites in the SH (Southern Hemisphere) show winter maxima and summer minima. At the subtropical and tropical sites, there are large day-to-day variations that reflect the changes in flow patterns.
