SUPPLEMENTARY INFORMATION: 

I. Summary of Information About the Project/Document

    The ``2007 Interim Report of the U.S. EPA Global Change Research 
Program Assessment of the Impacts of Global Change on Regional U.S. Air 
Quality: A Preliminary Synthesis of Climate Change Impacts on 
O3'' is intended to provide air quality managers and 
scientists a summary and synthesis of the scientific results that have 
emerged from the EPA ORD Global Change Research Program (ORD GCRP) 
assessment of the impact of global change on U.S. regional air quality. 
The report discusses the studies that have focused on the sensitivity 
of U.S. air quality to meteorological changes associated with a warming 
climate in large regions within the continental U.S.
    The EPA recognizes that climate-air quality interactions occur at 
multiple scales (both spatial and temporal), and that an understanding 
of these interactions demands contributions from several scientific 
disciplines. The EPA ORD GCRP developed a research and assessment 
program that combines the resources and expertise of the ORD labs and 
centers toward the goal of developing the necessary scientific 
underpinnings. The ultimate goal of the Program is to provide air 
quality managers with the scientific information and tools needed to 
evaluate the implications of global change and to enhance their ability 
to consider global change in their decisions. The ``2007 Interim Report 
of the U.S. EPA Global Change Research Program Assessment of the 
Impacts of Global Change on Regional U.S. Air Quality: A Preliminary 
Synthesis of Climate Change Impacts on O3'' is a preliminary 
step in that direction.
    This report provides an update of the progress that has been made 
in applying climate and atmospheric chemistry models to investigate 
potential future meteorological effects on air quality. It does not 
include changes in air pollutant emissions other than those that are 
explicitly linked to meteorological variables and incorporated within 
the models (e.g., biogenic VOC emissions). In addition, it provides a 
preliminary interpretation of what this improved scientific 
understanding means for air quality management. Future assessment 
reports will cover the combined impacts of changing climate and air 
pollutant emissions on air quality. The program also plans to develop 
additional reports that focus on additional pollutants, including PM 
and mercury.
    NCEA worked collaboratively with the EPA Office of Air and 
Radiation (OAR), and ORD's National Risk Management Research Laboratory 
(NRMRL), National Exposure Research Laboratory (NERL) and National 
Center for Environmental Research (NCER) on this report.
