Abstract

Airborne lidar measurements of the mixed layer were made during the summer months of 1980 and 1981 using the Ultra-Violet Differential Absorption Lidar (UV DIAL) system developed at the NASA Langley Research Center.¹ The UV DIAL system was operated on-board the NASA Wallops Electra aircraft to measure O₃ and aerosol profiles during long-range flights over the Eastern United States as part of the EPA Persistent Elevated Pollution Episodes/ Northeast Regional Oxidant Study (PEPE/NEROS) 1980 Summer Field Experiment. A subsequent Summer Experiment was conducted in 1981 to perform O₃ and aerosol measurements on spatial/temporal scales not investigated during 1980. This paper confines itself to the interpretation of this lidar data set for information on mixed layer dynamics.
