Particles in the Polar Stratospheres

Abstract

SINCE 1971, the University of Wyoming's atmospheric physics group has been monitoring the stratospheric concentration of submicron particles globally using the balloon sounding technique with a dustsonde1. Included in this programme are annual soundings from the ice island T-3, at present at about 85° N, and from McMurdo Station (78° S) and South Pole Station (90° S) in Antarctica. For reasons of accessibility measurements are made in both polar regions at approximately the same time—northern hemisphere winter. Thus the measurements were carried out at T-3 during December 1971 and December 1972 and at the South Pole during January 1972 and January 1973. We describe the results here.
