16 Sep 2011: International Day for the Preservation of the Ozone Layer
Europe monitors the ozone hole day after day, year after year
Today, we are celebrating the International Day for the Preservation of the Ozone Layer and the benefits brought about by the Montreal Protocol, 24 years ago.
The stratospheric ozone service of the European GMES-project MACC (http://www.gmes-stratosphere.eu) aims at monitoring stratospheric ozone and the chemical substances that destroy it in real time with networks of ground-based instruments, satellites and forecasting centers. MACC delivers daily forecasts of the evolution of the stratospheric ozone layer.
Ozone hole 2011 compared to previous years
MACC is following-up the evolution of the ozone hole year after year, both over the Arctic and over the Antarctic. To illustrate its evolution this year and compare it with previous years, BIRA-IASB has put together an animation showing the amount of ozone day after day during the months of August and September, for the years 2003 till 2011. It is based on the main NRT forecasting system of MACC, IFS-MOZART.
