AB: Measurements of ozone, reactive carbon and nitrogen, and other trace constituents from flights of the NASA WB-57 aircraft in the upper troposphere and lower stratosphere reveal that convection in the tropics can present a complex mix of surface emitted constituents right up to the altitude of the lapse rate tropopause. Trace gas measurements indicate that surface emissions from biomass burning, industrial combustion and processing, and marine biogenic sources were present in the upper troposphere during most research flights during the ACCENT mission during September, 1999. At latitudes over the southern US, the strongest detrainment, in terms of constituent mixing ratios, occurred in the potential temperature range of 340-350o K or approximately over the altitude range of 9-11 km, but weaker detrainment signals were also seen up to near the tropopause. There was no evidence of convective detrainment directly into the lower stratosphere from these flights.
