Ozone Assessment Panel Science Meeting in Geneva, Switzerland

CSL Director David Fahey, co-chair of the Montreal Protocol Scientific Assessment Panel, helped lead the 2022 Scientific Assessment of Ozone Depletion final author team meeting in Geneva, Switzerland from 25-29 July. Attendees, including ESRL scientists and staff, discussed and finalized the assessment's Executive Summary to be released by the Ozone Secretariat this fall.

The 2022 Scientific Assessment of Ozone Depletion is the 10th in the series. For each quadrennial assessment, CSL (and formerly the Aeronomy Laboratory) has assumed the large responsibilities of coordinating the assessment process (e.g., co-chair, author, and reviewer communication, assembling draft versions, meeting planning) and producing the final documents (main document, executive summary and 20 Questions and Answers), which involves editing, layout, printing, and distributing.
