Southern ozone variations induced by solar particle events during 15 January-5 February 2005

Abstract

A preliminary analysis of effects induced on the high-latitude Southern ozone layer by the enhanced Space Weather storms of January 2005 is presented. Data from Earth Probe TOMS V.8, SAGE II and POAM III suggest short (hours) ozone depletions induced by the outstanding solar activity. Such ozone variabilities are investigated at the edge of the so-called polar cap region.
