WMO Arctic Ozone Bulletins: 2016
The Secretariat of the World Meteorological Organization issues bulletins containing information on the state of the ozone layer in the Arctic and surrounding regions at roughly three week intervals from January to April. The bulletins are based on data provided by WMO Members which operate ozone monitoring stations in the Arctic region and satellites to observe ozone globally. Meteorological data and model results are also used to assess and interpret the observations.
