The primary goal of the Stratospheric Tracers of Atmospheric Transport (STRAT) campaign is the measurement of the morphology of long-lived tracers and dynamical quantities as functions of altitude, latitude, and season in order to help determine rates for global-scale transport and future distributions of high-speed civil transport (HSCT) exhaust emitted into the lower stratosphere. The observations will also improve understanding of broader issues involving transport of gases and aerosols in the stratosphere.
