Ozone Layer Recovery, and Implications for Ultraviolet Radiation Exposure (draft dated August 20, 2007). Next, the committee met with the SAP authoring team, who provided in-depth presentations of their research and material used to formulate the draft document. The committee met in closed session to discuss the draft SAP in detail. This present report constitutes the committee’s peer review of SAP 2.4 and results from the committee’s careful study of the draft and its interactions with those present at the meeting. This report includes the committee’s findings, recommendations, suggestions, and options for the authors to consider in finalizing SAP 2.4.
