A STUDY ON VERTICAL DISTRIBUTION OF OZONE IN THE PBL OF THE PHOENIX VALLEY

摘要

In general, ozone concentrations increase with height above the ground. During the nighttime, in particular, the ozone concentrations decreas sharply from the top of the surface inversion layer to the ground and displays an almost constant concentration within the residual layer (Nue et al., 1994; Teichmann et al., 1997; Gustenefa/., 1998). Previous studies (Neuefa/., 1994; Aneja et al., 2000) show a strong correlation between nighttime and early morning ozone concentrations in the residual layer andthe maximum ground level concentration in the following afternoon.
