The Copernicus Atmospheric Monitoring Service monitors stratospheric ozone levels and the evolution of the Antarctic ozone hole. It also supports efforts to preserve stratospheric ozone 35 years after signing the Montreal Protocol, which bans ozone-depleting substances.

Copernicus Atmospheric Monitoring Service (CAMS) He closely follows the evolution of the ozone hole over Antarctica. The hole has grown in size since late August and is now larger than Antarctica, which is the normal development for this time of year.
The ozone hole begins to form in the spring in the southern hemisphere from August to October and usually reaches its maximum between mid-September and mid-October. It forms over Antarctica due to the specific weather and chemical conditions present in the region.
CAS scientists have been monitoring the development of the ozone hole since late August, the beginning of spring in the Southern Hemisphere. Data from the EAS reveal that standards commonly used to track the evolution of the ozone hole have been in the middle range, compared to the past four decades, since early September, and are currently following the expected trend. However, scientists will closely follow its development after the very large and exceptionally persistent ozone holes in 2020 and 2021, when the stratospheric polar vortex was particularly strong.
Vincent-Henry Buch, Director of the Copernicus Atmospheric Monitoring Service, commented: “The Antarctic ozone hole 2022 began to develop at the end of August, and has so far followed the same trends as in the past decade in terms of area, lower total column, mass deficit and minimum temperature. “.
“According to our data from the beginning of September, the size of the ozone hole is within the medium range. But over the next few weeks, we will be watching developments closely as the 2020 and 2021 ozone holes begin to become exceptional later on.
International Day for the Preservation of the Ozone Layer
The United Nations International Day for the Preservation of the Ozone Layer, September 16, highlights how the Montreal Protocol and its subsequent amendments contribute to reducing the impact of human activities on the weak ozone layer that protects our planet from harmful exposure to ultraviolet radiation. (UV.
The Copernicus Atmospheric Monitoring Service (CAMS), implemented by the European Center for Medium-Range Weather Forecasts on behalf of the European Commission with funding from the European Union, supports international efforts to preserve the ozone layer through continuous monitoring and provision of its data. The current situation in this, the thirty-fifth anniversary of the signing of the Montreal Protocol.
Efficiency Assurance Management System (CAMS) is a leading provider of ozone data as well as information on air quality, greenhouse gases and climate impacts from a range of sensors, all freely available worldwide through Atmospheric Data Store (ADS). By combining satellite observations and in-situ observations with detailed digital models of the atmosphere, scientists can closely monitor the formation, evolution and closure of the ozone hole during the 2022 season.
“CAMS is one of the very few services in the world that can provide 3D predictions and analyzes of the state of the ozone hole – not just ‘total column’ ozone predictions and analyzes. This makes it possible to monitor the detailed structure of the ozone hole and the extent of its depletion as a function of the above-ground level. This information The mission is free for all and helps make informed decisions and take action.”

About Copernicus and ECMWF
Copernicus is part of the European Union’s Space Programme, which is funded by the European Union, the leading Earth observation programme. The company operates through six thematic services: Atmosphere, Marine, Land, Climate Change, Security and Emergencies. It provides freely available data and operational services that provide users with reliable and up-to-date information about our planet and its environment. The program is coordinated and managed by the European Commission and implemented in partnership with Member States, the European Space Agency (ESA), the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), the European Center for Medium Distance Forecasting (ECMWF), European Union agencies, Mercator Océan and others.
ECMWF operates two services of the European Union’s Copernicus Earth Observation Program: the Copernicus Atmospheric Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S). They also contribute to the Copernican Emergency Management Service (CEMS), which is implemented by the European Union Joint Research Council (JRC). The European Center for Medium Range Weather Forecasts (ECMWF) is an independent intergovernmental organization supported by 35 countries. It is a 24/7 operational research and service institute that produces and publishes digital weather forecasts to its member states. These data are fully available to the national meteorological services of the member states. The supercomputer facility (and associated data archive) at the ECMWF is one of the largest of its kind in Europe and member states can use 25 percent of its capacity for their own purposes..
ECMWF has expanded the number of sites in which it operates. In addition to the headquarters in the UK and the computing center in Italy, the new offices focusing on activities implemented in partnership with the European Union, such as Copernicus, will be located in Bonn, Germany.
