Abstract

Stratospheric aerosol surface densities and altitude integrated ozone number densities are derived from ground-based lidar measurements at Table Mountain, California (34°N) and Ny-Alesund, Spitsbergen (79°N) during three years following the Mt. Pinatubo eruption in June 1991. At mid latitude aerosol surface densities peak in December 1991. Variations of high latitude surface density data on time scales of days are controlled by dynamical processes. At Table Mountain ozone number densities integrated over the volcanic layer are reduced during late 1991 and throughout 1992 by 5–10%.
