WMO Ozone Bulletins

WMO Arctic Ozone Bulletins

The Secretariat of the World Meteorological Organization, in collaboration with the European Ozone Research Coordinating Unit, issues annual bulletins containing information on the development of the Arctic ozone layer over the course of each winter. The bulletins are based on data provided by WMO Members that operate atmospheric monitoring stations in the Arctic and satellites to observe ozone and related parameters globally.
