Coordinator/ Editor Chris Ennis (USA)
Goal: Make the assessment more useful to and usable by the Parties.
Make the printed copy short, easy to read, and provide much needed information for policy decisions.
Side benefits: Reduce printing and shipping costs A layered publication- easily accessible at various levels Taking advantage of the technological (internet) advances

Request (Decision XXIII/13)
“Terms of Reference” for the 2014 SAP Report a.
b. Evaluation of the Antarctic ozone hole and Arctic winter/spring ozone depletion and the predicted changes in these phenomena, with a particular focus on temperatures in the polar stratosphere; c.
Assessment of the state of the ozone layer and its future evolution, including in respect of atmospheric changes from, for example, sudden stratospheric warming or accelerated Brewer-Dobson circulation; Evaluation of trends in the concentration in the atmosphere of ozone-depleting substances and their consistency with reported production and consumption of those substances and the likely implications for the state of the ozone layer and the atmosphere; d. Assessment of the interaction between the ozone layer and the atmosphere; including: i. The effect of polar ozone depletion on tropospheric climate; e.
f.
g.
ii. The effects of atmosphere-ocean coupling; Description and interpretation of observed ozone changes and ultraviolet radiation, along with future projections and scenarios for those variables, taking into account among other things the expected impacts to the atmosphere; Assessment of the effects of ozone-depleting substances and other ozone-relevant substances, if any, with stratospheric influences, and their degradation products, the identification of such substances, their ozone-depletion potential and other properties; Identification of any other threats to the ozone layer…
