Comparison of stratospheric ozone variations in the Arctic and Antarctic during solar proton events

摘要

In this work the influence of solar protons of ground level event (GLE) type on stratospheric ozone were investigated. The asymmetry of ozone `mini-holes' caused by GLEs between the Arctic and Antarctic polar caps (N/S asymmetry) in terms of their spatial variations and possible mechanisms which are responsible for this asymmetry are discussed. There were considered GLE events: 29.09.89; 19.10.89; 24.10.89 and 21 - 28 May 1990 on data of balloon measurements and ground based ozone data of some Arctic and Antarctic observatories.
