Relation between Atmospheric Ozone and Geomagnetic Disturbances

Abstract

MANY attempts have been made in the past without much success to establish a relationship between anomalous solar activity such as solar flares, the consequent geomagnetic disturbances, etc., and atmospheric ozone. Most of the investigations made were of a statistical nature from observations at a single station. Recently, Sekihara¹ statistically concluded that there was a small increase in ozone on the eighth day after the key day of a magnetic storm. He used the data of total ozone amount mostly for stations between 10° N. and 47° N. This communication gives the results of the behaviour of the mean meridional distribution of total ozone over European stations during severe magnetic storms.
