AB: Measurements of short-lived organic compounds un the UTLS region have been used in a number of ways, including characterization of bromine and chlorine budgets, transport processes, and the age spectrum in the LS. The short-lived halogen source gases may play an important role in ozone chemistry in the UTLS, however, their source strengths and distributions are difficult to characterize due to spatial and temporal variations in emissions from organic halogens with natural origins. Recent airborne campaigns provide excellent opportunities to further characterize the mixing ratios and spatial distributions of the organic halogens as well as nonmethane hydrocarbons and alkyl nitrates in the tropical and midlatitude troposphere and lower stratosphere regions. This work will present a summary of measurements from TC4 and previous airborne campaigns of the organic halogen budgets and vertical distributions of selected short-lived organic compounds.
