Abstract : During the past three years there has been a national and international intensification of research programs to study the photochemical production and destruction of atmospheric ozone and its variations in a dynamic atmosphere. This intensified effort is in response to the realization that ozone, as a highly reactant gas, can be involved in a large number of chemical interactions with stratospheric trace substances (both 'natural' and 'artificially produced') to significantly vary its concentration in the stratosphere. Some important possible consequences of such interaction would be: (a) changes in solar ultraviolet radiation received at the ground with serious biospheric effects; (b) changes in the thermal and dynamic structure of the stratosphere with potential climatic implications. Two aspects of the so-called 'ozone problem' have been studied: (1) The analysis of the global distribution and variations of total ozone; (2) photochemistry of stratospheric ozone and its interaction with atmospheric circulation. This report describes the results of these studies.
