Abstract |
Diurnal curves of tropospheric ozone are characterized for the areas near coniferous forests in the western U.S. A given day of hourly data can be placed into one of 17 classes of diurnal curves simply by knowing the 24-h mean and coefficient of variation or range, or more precisely, by applying equations derived from our discriminant analysis. The variation among curves is shown to be related to theory of ozone formation, scavenging, and transport. Season, latitude, and position relative to source areas affect the form of the diurnal curve. (Copyright (c) 1991 Pergamon Press plc.) |
