Twenty years ago, on 16 September 1987, a group of countries signed the Montreal Protocol in a pivotal step towards protecting stratospheric ozone. According to the United Nations General Assembly, each 16 September is "International Day for the Preservation of the Ozone Layer." To commemorate this special Ozone Day, below we provide links to a selection of related online material.

Atmospheric ozone recovering in mid-latitudes, report shows . Press release (dtd 30 Aug 2006) from Georgia Institute of Technology. "Concentrations of atmospheric ozone -- which protects Earth from the sun's ultraviolet radiation -- are showing signs of recovery in the most important regions of the stratosphere above the mid-latitudes in both the Northern and Southern hemispheres, a new study shows. The study is the first to document a difference among stratospheric regions in ozone-level improvement and to establish a cause-and-effect relationship based on direct measurements by multiple satellite and ground-based, ozone-monitoring systems." |
