| Abstract |
The data from the summer 1975 Northeast Oxidant Study have been combined with routinely collected weather and pollutant data to demonstrate that oxidant and its precursors are transported for distances in excess of 100 km in the New York, New Jersey, and southern New England region. Vertical cross sections of ozone concentration clearly show urban ozone plumes. During a daytime passage of a weather front, strong ozone gradients are observed between the warm polluted air ahead of the front and the clearer, cooler air behind; at any fixed site, concentrations drop rapidly as the front passes and clean air replaces polluted. Nighttime frontal passages do not show the marked ozone gradients found during a daytime frontal passage. High nighttime ozone concentrations are associated with the simultaneous occurrence of unusual vertical mixing and an ozone layer aloft. The ozone layer aloft appears to be the remnant of daytime photochemical production in an urban plume. |
