This paper reports results from measurements performed to study the cross polar vortex transport properties, using the aerosols injected by the Mt. Pinatubo eruption. The initial aerosol cloud arrived prior to the establishment of the polar vortex in 1992. However, using balloon borne backscattersondes, the authors were able to sample the aerosol densities in the vortex during the 1992 winter season. At altitudes below 20 km, the density rose dramatically following a mid January disturbance of the vortex. By comparison, at altitudes above 20 km there was no significant increase observed through mid March.
