Antarctic Ozone Hole Evolution: 1979-2010 Satellite Imagery #1809925 (License: Personal Use)

This composite displays four key moments in the evolution of the Antarctic ozone hole: September 17, 1979 (initial detection), October 7, 1989 (peak expansion era), October 9, 2006 (largest recorded extent), and October 1, 2010 (early post-Montreal Protocol trends). Color scales represent total ozone column density, with purple/blue indicating severe depletion and yellow/green showing healthier levels. The images highlight the impact of chlorofluorocarbons (CFCs) and the slow recovery following international regulation.

Used in environmental science articles, educational resources, and climate policy reports to illustrate long-term atmospheric change; targets users seeking authoritative visual proof of ozone layer dynamics and Montreal Protocol effectiveness.
