WMO Antarctic Ozone Bulletins: 2015
The Secretariat of the World Meteorological Organization issues bulletins containing information on the state of the ozone layer in Antarctica and surrounding regions at roughly two-three week intervals from August to November. The bulletins are based on data provided by WMO Members which operate ozone monitoring stations in the southern hemisphere and satellites to observe ozone globally. Meteorological data and model results are also used to assess and interpret the observations.
