Physics and Chemistry of Atmospheres.

The Advanced Study Institute, Physics and Chemistry of Atmospheres, held at the University of Liege, Liege, Belgium, July 29 - August 9, 1974, was attended by 119 persons from 10 different countries. The objective of the Institute was to correlate the diverse aspects of atmospheric research to achieve a better understanding of the atmospheres of the Earth as well as the nearer planets. Not only aerodynamics, astronomy, chemistry, and physics are involved, but each of these, particularly physics, is highly subdivided. This paper is a summary of some of the significant findings reported at the Institute.
