The 2014 WMO/UNEP assessment, Scientific Assessment of Ozone Depletion: 2014, contains the most up-to-date understanding of ozone depletion. It reflects the thinking of hundreds of international scientific experts who contribute to its preparation and review. Cochairs of this Ozone Assessment were Dr. A.R. Ravishankara of Colorado State University and the NOAA ESRL Chemical Sciences Division, USA, Dr. Paul A. Newman of the NASA Goddard Space Flight Center, USA, Dr. John A. Pyle of the University of Cambridge, UK, and Dr. Ayité-Lô Nohende Ajavon of the North-South Environment, Togo. Other members of the ESRL Chemical Sciences Division are making substantial contributions to the report, serving as coauthors, contributors, reviewers, coordinating editor, and editorial and computing support staff.
This Ozone Assessment consists of an Assessment for Decision-Makers, five detailed scientific chapters, and the Twenty Questions and Answers About the Ozone Layer: 2014 Update.
