independent oversight and review from the wider scientific and stakeholder communities (NRC, 2004). To meet this goal, NOAA has requested an independent review of SAP 3.2 by the NRC. The NRC appointed an ad hoc committee composed of eight members (Appendix C). The committee’s Statement of Task is included in Appendix D.
The committee conducted its work by first carefully reading the draft SAP 3.2 report “Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols” (draft dated May 9, 2007). The committee then met with the lead authors to ask questions about the authoring team’s research and formulation of the draft document. During this meeting, the committee also interacted with NOAA personnel, who outlined for the committee their expectations for SAP 3.2. This present document constitutes the committee’s review report, resulting from its careful study of the draft SAP 3.2 document and its interactions with those present at the aforementioned meeting. Herein the committee provides its review findings, and recommendations, suggestions, and options for the authors to consider in revising the draft SAP 3.2. In its review, the committee focused on substantive matters of content and did not proofread the document for grammatical or typographical errors.
