ABSTRACT

The ozone-climate inter-relations and feedbacks are emerging as significant components that contribute to the understanding of Earth system science. The atmospheric ozone plays a fundamental role in both the terrestrial ecosystem and global climate. Although the study of the stratospheric ozone started in the early 20th century, observations strengthened in the 1980s after discovering the “ozone hole” over Antarctica. The stratospheric ozone layer extends between 10 and 40 km altitude, peaking at about 25 km and containing more than 90% of all atmospheric ozone. Atmospheric ozone has two significant effects on the temperature balance of the Earth. The ozone layer absorbs the most damaging part of UV radiation, which heats the stratosphere and plays a vital role in preventing UV radiation from reaching Earth’s surface.
