Abstract

The summer season of 1995 in the northeastern United States was characterized by high temperatures, low rainfall and high ambient 03. The high 03 episode of July 12-15, 1995 was one of the strongest regional 03 events since 1988. During this event, intensive observations were undertaken by the University of Maryland (UM) along with the NARSTO-Northeast project. This paper summarizes the results from observations made by the UM aircraft operating upwind of the Baltimore metropolitan area as well as supplemental radiosondes and chemical data from UM sites well upwind and downwind of the region. The observations show that a strengthening low level inversion, high temperatures and strong boundary advection of 03 and its precursors, all associated with the eastward movement of a strong upper air ridge, caused 03 to increase steadily throughout the episode and that the effects were felt at distances well downwind of the Baltimore area.
