Title: Tropospheric Ozone Variability during LASIC Field Campaign Report

Abstract

Part of the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility’s Layered Atlantic Smoke Interactions with Clouds (LASIC) field campaign. The primary goal of the measurements was to improve understanding of the evolution of the wave-one ozone maximum. The key objectives were Measure the variability of ozone mixing ratios associated with the African Easterly Jet (AEJ) on sub-synoptic time scales in which meteorology may play a role. In concert with weekly measurements from the Southern Hemisphere Additional Ozonesondes (SHADOZ) network, determine the vertical distribution of ozone and aerosols at Ascension Island. Determine from lidar measurements the locations of the biomass burning (BB layer) and its relationship to ozone mixing ratios. Determine the relative abundance of ozone in the BB layer relative to ozone mixing ratios at higher altitudes that may be associated with lightning nitrogen oxides (LNOx). Determine sources of high or low ozone mixing ratios through back trajectory models at Ascension Island.
