1. Description of Topic, Audience, Intended Use, and Questions to be Addressed

1.1. Introduction

This prospectus has been prepared according to the Guidelines for Producing Climate Change Science Program (CCSP) Synthesis and Assessment Products. The prospectus will be reviewed and approved by the CCSP Interagency Committee. The document describes the focus of this Synthesis and Assessment Product and the process that will produce it. The document does not express any regulatory policies of the United States or any of its agencies, or make any findings of fact that could serve as predicates for regulatory action.

The Atmospheric Composition chapter of the CCSP Strategic Plan describes a vision to produce a Synthesis and Assessment Product (SAP) on “Trends in emissions of ozone-depleting substances, ozone layer recovery, and implications for ultraviolet radiation (UV) exposure–SAP 2.4.” As part of the CCSP Goal 2, SAP 2.4 will provide a synthesis and integration of the current knowledge of the stratospheric ozone layer, ozone-depleting substances, and ultraviolet radiation reaching the Earth’s surface.

This product will contribute to and enhance the ongoing and iterative international process of producing and refining climate-related assessments and decision support tools.  For instance, SAP 2.4 will integrate findings from the Word Meteorological Organization (WMO) / United Nations Environment Programme (UNEP) 2006 assessment on the ozone layer, and the 2005 Special Report of the Intergovernmental Panel on Climate Change (IPCC) on Safeguarding the Ozone Layer and the Global Climate System – Issues Related to Hydrofluorocarbons and Perfluorocarbons.  It will discuss these assessments in the context of the United States of America.  The SAP will discuss ozone changes over North America, the contributions of the USA to ozone-depleting substances, and the UV changes due to the ozone layer changes over the North American continent.  This Synthesis and Assessment Product will take advantage of these thoroughly vetted scientific assessments to prepare a product that can be used to inform domestic and international decision makers in government and industry, scientists, and the public. 

1.2. Topic and Content

SAP 2.4 will address key issues related to the stratospheric ozone layer, including its changes in the past and expected levels in the future.  Also, it will take account of the current abundances and emissions of ozone-depleting substances.  Further, it will synthesize the best available information on the past and future levels of ultraviolet radiation at the Earth’s surface.  Lastly, it will explore the interactions between climate change and stratospheric ozone changes.  All of this will be carried out within the context of the USA to distill a regional assessment from the global assessments.  More specifically, SAP 2.4 will:

  • Quantify current information on sources, sinks, and abundances of ozone-depleting substances and associated uncertainties.  It will quantify the atmospheric lifetimes, the ozone depletion potentials, and global warming potentials of many important past, present, and future emissions.
  • Discuss levels of ozone in various regions of the stratosphere, including the polar regions.  It will pay special attention to the Antarctic ozone hole.
  • Provide information on the past, current, and future levels of ultraviolet radiation.
  • Provide an assessment of the impact of climate and compositional changes on the future of the ozone layer.
  • Identify where research supported by CCSP agencies is critical for future assessments of the ozone layer.
  • Describe how these findings relate to human activities, with a particular emphasis on the U.S.

See Attachment 1 for more details

Note: The report will cover the radiative forcing due to stratospheric ozone trends but will not extensively cover the impact of the trends on climate variability and change.   A few
impacts on climate will be noted and described qualitatively.

1.3. Audience

The audience for SAP 2.4 includes scientists, decision makers in the public sector (Federal, State, and local governments), the private sector (chemical industry, transportation, and agriculture; and climate policy and health-related interest groups), the international community, and the general public. This broad audience is indicative of the diversity of stakeholder groups interested in knowledge of the stratospheric ozone layer, ozone-depleting substances, and ultraviolet radiation, and of how such knowledge might be used to inform decisions. The primary users of SAP 2.4 are intended to include, but are not limited to, officials involved in formulating climate and environmental policy, individuals responsible for managing emissions of ozone-depleting substances, and scientists involved in assessing and/or advancing the frontier of knowledge.

1.4. Intended Use

SAP 2.4 will be used (1) as a state-of-the-art assessment of our knowledge of the stratospheric ozone layer, ozone-depleting substances, and ultraviolet radiation at the surface; (2) to provide the scientific basis for decision support to guide management and policy decisions that affect the ozone layer and emissions of ozone-depleting substances; (3) as a means of informing policymakers and the public concerning the general state of our knowledge of the stratospheric ozone layer and emissions of ozone-depleting substances with respect to the contributions of and impacts on the United States; and (4) to provide scientific information on the ozone layer to inform important stakeholder groups. Examples of these groups include: the chemical industry that produces substitutes of ozone-depleting substances; sectors of the U.S. economy that request exemptions from emissions of substances banned by the Montreal Protocol and its Amendments; and the climate-science community. Senior managers and the general public may use the Executive Summary of SAP 2.4 to improve their overall understanding of what is known and unknown about the effects of U.S. emissions on the stratospheric ozone layer and ultraviolet radiation at the surface.  It will also provide an estimate of the impacts of the ozone layer changes on the country.

1.5. Questions to be Addressed

Questions to be addressed by SAP 2.4 include:

  • What is the current state of the stratospheric ozone layer?
  • What are the recorded changes in the emissions and concentrations of ozone-depleting substances?
  • What do the observations indicate about the abundances and trends of stratospheric ozone?
  • What is the trend in the occurrence, depth, duration, and extent of the Antarctic ozone hole?
  • What is the state of ozone depletion in the Arctic region?
  • When can one expect recovery of the global ozone layer and of the Antarctic ozone hole?
  • What are the influences of climate change on the recovery of the ozone layer?
  • How has surface ultraviolet radiation changed in the past and what is expected for the future?
  • What are the various possible emission scenarios that can be considered for any further policy actions on emissions of ozone-depleting gases?

These questions are starting points for producing SAP 2.4; they were developed by the proposed SAP 2.4 Author Team (see Section 3) and refined based on the deliberations for the two international assessments that were noted earlier.  The draft outline of major sections of the report is included in Attachment 1 to this prospectus.

The SAP 2.4 Author Team will be responsible for organizing and outlining SAP 2.4 and for its final content and submission to NOAA. They will provide all the inputs to SAP 2.4 and will lead the overall synthesis and integration of the report. They will provide oversight and editorial review of individual chapters and will prepare any overview chapters and the Executive Summary. Their biographies are provided in Attachment 2. Drs. Kurylo and Ravishankara will coordinate the SAP 2.4 Author Team’s activity.

The responsibility for writing each individual chapter of SAP 2.4 has been assigned to one or more scientific experts in the topic area of the chapter; this person (or persons) will be designated the lead chapter author(s). These authors were chosen for their recognized expertise in various specific areas that are covered in the product.  This is based on the quality and relevance of current publications in the peer-reviewed literature pertaining to their chapter topics, past or present positions of leadership in the topic fields, and other documented experience and knowledge of high relevance. All authors will be listed in association with their contributions (e.g., chapters) in the final report.

Their biographies are provided in Attachment 2. The SAP 2.4 contributing agency leads discussed the draft chapter outline and candidate chapter authors in their initial meeting held at NASA Goddard Space Flight Center in Maryland on May 22, 2006.

4.  Stakeholder Interactions

A process for engaging important stakeholder groups and establishing an ongoing dialogue with them is a priority activity. Stakeholder involvement is essential to ensure transparency – open access to information on the SAP 2.4; feedback on relevance – review and comment on the SAP 2.4 process and verification that information produced by the SAP 2.4 will be useful; and credibility – recognition by the stakeholders of the scientific validity and independence of the SAP 2.4. These activities will be the responsibility of the SAP 2.4 Author Team. 

As a first step in this process, the plan for this SAP was presented at the CCSP workshop, “U.S. Climate Change Science Program, Climate Sciences in Support of Decision Making,” held in Arlington, Virginia, during 14-16 November 2005, where it was well received

Further stakeholder input will be solicited through the public comment period for this prospectus and the public comment period for the draft final report. All comments submitted during the public reviews will be made publicly available and these comments will be carefully considered by the authors.

5. Drafting Process (Including Materials to be Used in Preparing the Product)

The SAP 2.4 contributing agency leads have discussed the draft chapter outline (see Attachment 1) in their initial consultations with science, government, and other stakeholders.  Additional venues for input will be explored; if found, they will be posted on the CCSP website.  However, it is anticipated that the input to the web-posted prospectus will be the major input from the public.

The two international assessments, which were vetted by hundreds of scientists from around the world, form the basis of the SAP product. 

All authors will be provided with NOAA’s Information Quality Guidelines as specified in the Guidelines for Producing CCSP Synthesis and Assessment Products, which will include compliance with the overall Office of Management and Budget (OMB) guidelines: OMB Guidelines for Ensuring and Maximizing the Quality, Objectivity, Utility, and Integrity of Information Disseminated by Federal Agencies and the Information Quality Bulletin for Peer Review.

The authors of SAP 2.4 will be expected to emphasize accuracy and precision of numerical information, confidence levels, and characterization of uncertainties. SAP 2.4 will provide a clear discussion of uncertainties and how uncertainties may be reduced, preferably through a section of each chapter in which measurements, model results, or combinations of data and models occur. Whenever appropriate and possible, numerical values will be accompanied by measures of uncertainty (e.g., ± x units or percent). Where the uncertainty cannot be quantified, an explanation or justification will be given.

To ensure consistency and thoroughness in the treatment of uncertainties across all chapters of SAP 2.4, the SAP 2.4 Author Team will maintain regular oversight of overall data and information quality as presented in workshops and in draft text.

6. Review

NOAA will ensure that SAP 2.4 is reviewed at all stages as specified in the Guidelines for Producing CCSP Synthesis and Assessment Products and consistent with the Information Quality Act and Information Quality Bulletin for Peer Review, that comments and other feedback are provided to the SAP 2.4 Author Team for response, and that comments and responses are documented and made publicly available.

6.1. During Drafting Period

The SAP 2.4 Author Team will post on the CCSP web site the list of authors and draft versions of the outline, with a mechanism for providing comments through the web site. The SAP 2.4 Author Team will also establish a process and standards for ongoing information quality review.

6.2. Expert Review of First Draft

NOAA will coordinate a formal expert review through the National Research Council (NRC) of the U.S. National Academy of Sciences in 2007.  This review will be conducted according to the policies and procedures of the National Research Council (NRC).

6.3. Public Review of the Second Draft

After revision in response to the expert review, the second draft of SAP 2.4 will be released for public comment.  The public comment period will be 45 days.  Following this comment period, the authors will prepare a third draft of the report, taking into consideration the comments submitted during the public comment period.  The scientific judgment of the authors will determine responses to the technical comments.  All comments submitted during the public review will be made publicly available. The public comment period will begin after the NRC review and is expected to occur toward the end of 2007. The public will have the opportunity to access the NRC review of the report prior to the 45-day public review period.

6.4. CCSP and National Science and Technology Council (NSTC) Review of the Third Draft

Once the revisions to the second draft are complete, the SAP 2.4 Author Team will submit the third draft of the Synthesis and Assessment Product to NOAA. Once NOAA determines that the report conforms to CCSP and IQA guidelines, it will submit the draft product and a compilation of the comments received to the CCSP Interagency Committee.  If the CCSP Interagency Committee determines that further revision is necessary, their comments will be sent to NOAA to seek consideration and resolution by the SAP 2.4 Author Team. If needed, the NRC will be asked to review the revised SAP.

After the CCSP Interagency Committee review determines that no further revisions are needed and NOAA certifies that the report has been prepared in conformance with the Guidelines for Producing CCSP Synthesis and Assessment Products and the Information Quality Act (including ensuring objectivity, utility, and integrity as defined in 67 FR 8452), the CCSP Interagency Committee will submit the report to the National Science and Technology Council (NSTC) for clearance. Clearance will require the concurrence of all members of the Committee on Environment and Natural Resources. The CCSP Interagency Committee will be responsible for ensuring that comments generated during the NSTC review are addressed.  They will consult with NOAA and the authors to develop an appropriate response.  If the Synthesis and Assessment Product should need to be revised, the revisions will be written by the SAP 2.4 Author Team and then routed back through NOAA and the CCSP Interagency Committee to the NSTC. 

After clearance and prior to publication, the SAP 2.4 Author Team will be given the opportunity to examine the final report. If at this stage, or any earlier stage in this process, an individual author cannot accept the outcomes of the writing, review, and revision process, they will be accorded the opportunity to withdraw their name from the publication.

7. Related Activities, Including Other National and International Assessment Processes

SAP 2.4 will utilize, to the maximum extent possible, the information available from two international assessments: the WMO/UNEP 2006 assessment on the stratospheric ozone layer, to be released in spring of 2007, and the Special Report of IPCC on Safeguarding the Ozone Layer and the Global Climate System- Issues Related to Hydrofluorocarbons and Perfluorocarbons published in 2005.  When necessary, other existing data, programs, publications, and related activities in the United States or elsewhere will be used for input.

8. Communications: Proposed Method of Publication and Dissemination of the Product

Once the National Science and Technology Council(NSTC) clearance has been obtained, NOAA will coordinate publication, printing, and release of SAP 2.4. SAP 2.4 will be made available through the CCSP Office; it will also be made available electronically on both the CCSP and NOAA web sites.  The published report will follow the standard format for all CCSP Synthesis and Assessment Products.

The SAP 2.4 Author Team and other participants in SAP 2.4 will publicize the SAP 2.4 process widely. The purposes are to disseminate information about the process and to encourage key stakeholders to use the SAP 2.4 report as a tool to promote informed management and decision-making. A package of material will be created for all those involved in the SAP 2.4 to use as they travel in their ongoing professional work.

Attachment 1.
Chapter Structure and outline of Synthesis and Assessment Product 2.4: TRENDS IN EMISSIONS OF OZONE-DEPLETING SUBSTANCES, OZONE LAYER RECOVERY, AND IMPLICATIONS FOR ULTRAVIOLET RADIATION EXPOSURE

1. Introduction (Kurylo, Ravishankara, and Schmoltner)

This section will introduce the material to be covered under SAP 2.4, with an emphasis on how the Montreal Protocol (together with its Amendments and Adjustments) has been effective in protecting the stratospheric ozone layer from further destruction by halocarbons and what its global and national implications are for changes in ultraviolet radiation exposure and climate change.

2. Current trends, mixing ratios, and emissions (ozone- & climate-related chemicals) (Montzka, Vick, Cohen, Daniel)

This chapter will focus on a discussion of recent changes in the production, emission, and atmospheric burden of ozone-depleting substances (ODS) and long-lived replacements.  The role of the Montreal Protocol in bringing about these changes will be highlighted.  A discussion of banks (ODSs produced but not yet emitted), critical use exemptions, and other factors pertinent to the present and future atmospheric burden of halogens will be included.  Recent changes in total atmospheric chlorine, bromine, and equivalent chlorine from these long-lived gases will be reviewed to allow a discussion of the relevance these changes have had or will have for the ozone layer.  Finally, aggregate changes in the radiative forcing supplied by ODSs and their replacements will be reviewed to gauge the influence these changes might have had or will have on climate. The atmospheric abundances of the ozone-depleting gases as reported by NOAA and NASA to comply with the congressional mandate of the Clean Air Act, will be discussed.

3. Ozone & UV observations (Herman, Newman, Bevilacqua, Keating)

This chapter will briefly review observations and current understanding and uncertainties in long-term trends in ozone and ground ultraviolet radiation levels.  Because of fundamentally different properties and issues, the chapter will treat the polar regions separately from the low and mid-latitudes.  For each of these main geographic regions, both total column and ozone profiles will be discussed. Total column ozone and the vertical profiles of ozone in the following regions will be examined: Mid- and low latitudes, polar Northern Hemisphere, and polar Southern Hemisphere (ozone hole). Ground-level ultraviolet radiation levels in the following regions will also be examined: Mid- and low latitudes, polar Northern Hemisphere, and polar Southern Hemisphere.

Each of these broad categories will be broken down into ground-based and satellite observations for well-established techniques.

4. How do climate change and stratospheric ozone loss interact?  (Fahey, Douglass, Schmoltner, and Ramaswamy)

This chapter will examine the coupling between ozone depletion from ODSs and changes to the earth’s climate, including stratospheric temperatures changes during the past two decades, due in part to increased radiative forcing from growing greenhouse gas abundances.  It will also examine the impact of cooler stratospheric temperatures on stratospheric ozone amounts.  It will examine the influence of changed ozone abundance, particularly in southern polar regions, on circulation not only in the stratosphere but also in the troposphere.  It will further explore the influence of changes in circulation caused by climate forcing, such as increases in the global transport of air from the troposphere to the stratosphere, on ozone concentrations. The projected future ozone amounts will be examined based on our current understanding of the coupling of stratospheric ozone to climate parameters. The chapter will emphasize the return to periods when ODSs concentrations decline to pre-1980 values and the changes in climate parameters in the next century.

5. The future & recovery (Ko, Daniel, Herman, Newman, and Ramaswamy)

Using the emission scenarios from the WMO/UNEP ozone assessment, the corresponding concentrations of ODSs will be presented along with species specific contributions to Equivalent Effective Stratospheric Chlorine (EESC) and to instantaneous radiative forcing.  These scenario results will be assessed to demonstrate the extent to which production- and emission-limiting actions can still affect the future evolution of ODSs.  The expected responses in global ozone, Antarctic ozone, and UV at the surface will be discussed based on the EESC results. The possible implications of future climate changes will also be discussed.
