Objetivo This research project concerns the global change of the lower and upper atmospheric environment, and in particular how varying solar activity influences these areas including the stratospheric ozone and the climate of the Earth. This is an important scientific topic because a number of existing observations indicate a close correlation between these phenomena but no physical mechanism has yet been found. The topic is important also for economic and political reasons because scientific advances in this area could significantly enhance the possibility of making a distinction between natural and anthropogenic causes of changes in the environment. The research group consists of three institutes from Denmark, United Kingdom and Russia and form the core of the research which constitutes a promising combination of theoretical and experimental knowledge. The latter has been illustrated by the extensive geophysical activities carried out by the Danish group in the Arctic regions of Greenland and complementary activities in the Russian Arctic regions carried out by the Russian group. The long-term geological time scale aspect of global change is being extensively studied by the British group and is an important element for understanding the types and size of natural climatic fluctuations. Results of the investigation will be presented during the annual European meeting on atmospheric studies by optical methods. One report will be presented on the nature of ozone miniholes caused by very energetic solar protons and another on enhancement of stratospheric aerosols after the solar proton event of 16 February 1984. These reports will be published in the proceedings of the meetings. Two papers will be published in Geomagnetism and Aeronomy.
