Abstract

The Oslo ozone station on 60 degree(s) N has been in continuous operation since 1978. The measured ozone values for this station seem to be rather representative for the Arctic region. All the observed data have recently been reanalyzed and the results are given. In the period from 1978 to 1993 the ozone decrease is approximately 4.5%. The winter values (average of December, January, February, and March) decreased by approximately 9% whereas the summer values (average of May, June, July and August) decreased 2.3% in the 15 year period. The volcano eruptions from El Chichon and Mt. Pinatubo seem to influence the ozone layer.
