Infrared remote sensing of atmosphere at the Jungfraujoch station - Evidence for global changes

The thread imposed upon the earth"s atmosphere by anthropogenic activities is becoming well documented. Analyses of infrared solar observations carried out at the International Scientific Station of the Jungfraujoch, Switzerland, in 1950-51 and more intensively since the late 1970s have contributed to that documentation. This paper summarizes original findings arrived at so far and raises the need for intensive and coordinated observational programs during the 1990s.
