Monitoring changes in atmospheric ozone


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at how scientists monitor changes in atmospheric ozone.

While ozone protects life on Earth from harmful UV radiation, it is also a potent greenhouse gas, and its levels often change with the seasons. As a result, scientists keep a close watch on ozone concentrations using satellites that detect UV light.

Most atmospheric ozone exists in the stratosphere, where it sits 3 to 15 miles above Earth’s surface.
