Project H108
Synthesis of research findings in the aftermath of multiple TexAQS II

Project Period:06/01/2008 - 10/31/2008
Total Budget:$100,000
Sub-Contractors:University of Houston

The purpose of this project is to summarize recent information pertaining to the analysis of data from the Second Texas Air Quality Study (TexAQS II), as well as other research studies funded by TERC and/or TCEQ, and their importance to the Texas State Implementation Plan (SIP) for ozone attainment. This synthesis of scientific information will be aimed primarily at those who are responsible for helping to set TERC’s scientific agenda, and secondarily at TERC’s larger stakeholder community, including policy makers who need to know what the research community has accomplished in order to properly evaluate control strategy options for the SIP. No recommendations will be made on specific policies required to bring Texas into attainment of the ozone standard.

The new synthesis report will, like the science assessments by the Intergovernmental  Panel on Climate Change (IPCC), consist of an Executive Summary aimed at a policy audience, backed by more in-depth technical review in the main body of the text. However, unlike the IPCC assessments, most of the main body of the 2008 TERC Science Synthesis will be less a comprehensive literature survey than an explication of the technical reasoning behind a list of main conclusions, much like the TexAQS II Rapid Science Synthesis Report. The conclusions will then be listed in the Executive Summary, with only brief references to the scientific underpinnings.

The synthesis report will consist of three basic parts. Part I will be entitled “Background and Motivation” and will consist of an introduction summarizing TERC’s efforts leading up to the current synthesis, a discussion of outstanding SIP issues needing to be resolved from the perspective of regulatory requirements, and an outline of the key uncertainties affecting the evaluation of control strategies with air quality models. Part II will summarize the most important results of TexAQS II and ancillary studies, such as the TCEQ DIAL Study, that may help to resolve the key modeling uncertainties identified in Part I. Part III will then provide a summary and a list of conclusions, including a prioritization of new research required for supporting efforts to attain the new 75 ppb ozone National Ambient Air Quality Standard. An overall Science Plan for TERC’s upcoming field campaign, to be known as the Study of Houston Atmospheric Radical Precursors (SHARP), will be provided as an Appendix.
