For animation, a very important video was selected about the destruction of the ozone layer produced by the ECMWF (European Centre for Medium-Range Weather Forecasts). It shows that the diminution of the concentrations of the ozone layer in the stratosphere has as consequence the formation of the ozone hole over the antarctic continent. A each year the hole se expands due to presence of gases undesirable and to the complex meteorological processes and the photochemical reactions that occur continuously in the stratosphere.
