The Recovery of the Earth’s Ozone Layer

The reward for continuous international efforts to reduce atmospheric concentrations of ozone-depleting substances (e.g. chlorofluorocarbons (CFCs)) is beginning to materialise - climate scientists, using three decades of ozone measurements (from multiple instruments/satellites, harmonised under ESA’s Climate Change Initiative (CCI) Ozone project), are now seeing a trend indicative of the global recovery of the Earth’s ozone layer. The ozone layer, which resides in the Stratosphere, protects life on the Earth’s surface from harmful exposures to ultraviolet (UV) radiation from the Sun and so its presence and preservation is important.
