The Ozone Layer - Stratospheric Protection and Environmental Impact

Explore the critical role of stratospheric ozone in protecting Earth from harmful ultraviolet radiation in this 41-minute lecture from Yale University's course on The Atmosphere, the Ocean and Environmental Change. Learn about the structure and function of the ozone layer, measurement units like the Dobson Unit, and the chemical processes that create and destroy ozone. Examine the causes and impacts of the ozone hole, including the effects of chlorofluorocarbons (CFCs). Discover how the 1987 Montreal Protocol has helped address ozone depletion by banning CFC emissions. Gain insights into atmospheric chemistry, environmental policy, and global efforts to protect the ozone layer through this comprehensive overview.
