Abstract

An estimated 20-30 megatons of SO"SUB 2" and crustal material was injected into the stratosphere during June 12-16, 1991, by the eruption of Mount Pinatubo (15.1 degrees N, 120.4 degrees E). The impact on Antartic aerosol characteristics is of utmost concern owing to the seasonality in the observed ozone depletion and climate implications. This study focuses on Antarctic stratospheric aerosol characteristics during three temporal periods: September 23-30, September 30 to October 13, and November 13-27, 1991, at latitudes poleward of 60 degrees S for vertically averaged characteristics, and at latitudes poleward of 50 degrees S for temporal and spatial characteristics. Stratospheric aerosol characteristics are inferred from the Stratospheric Aerosol and Gas Experiment (SAGE) II measurements using a modified randomized minimization search technique (RMST). Aerosol characteristics such as size distribution, number concentration, mass loading, surface area concentration, and radical characteristics are derived between 15 and 30 km for particles having radii between 0.1 and 0.8 mum.
