Scientific Assessment Panel (SAP)
The Scientific Assessment Panel (SAP) assesses the status of the depletion of the ozone layer and relevant atmospheric science issues. Pursuant to Article 6 of the Montreal Protocol on Substances that Deplete the Ozone Layer, a report is prepared every three or four years by the SAP which consists of hundreds of top scientists from around the world. Any emerging scientific issues of importance are brought to the attention of the Parties by the SAP Co-Chairs for consideration at the Meetings of the Parties.
Preparation of the Scientific Assessment of Ozone Depletion reports
The four panel Co-Chairs, with input from an ad-hoc international steering group of researchers plan the scope, content, and authors of the assessment reports. The Co-Chairs and the relevant set of lead authors meet to plan and coordinate the contents of the chapters and the preparation of first drafts. The authors are aided by information contributed by a large body of researchers worldwide. The resulting drafts undergo peer review (with several reviewers per chapter) and a subsequent weeklong panel review, at which the chapter conclusions are agreed upon and the Executive Summary is finalized.
The Executive Summary for the 2010 report was published in September 2010 and the full report was published in January 2011. Each report contains a full list of the lead authors, the authors, the contributors and the reviewers.
