Description:
Objective:The overall objective of this research consortium was to advance the understanding of emissions/air quality relationships for ozone and fine particles in the two most populous areas of the United States: California and the Northeastern United States. The specific objectives of the Center were to: (1) improve the description of the physics and chemistry that is incorporated into air quality models that simultaneously predict ozone and fine particle formation and transport; (2) design and implement numerical algorithms to solve the atmospheric diffusion equation on computers having parallel architectures; (3) create a regional understanding of emissions/air quality relationships for ozone and fine particles in Southern California; and (4) develop and evaluate a multi-scale ozone and particulate matter model for the Northeastern United States and use the model to create a regional understanding of the cause and effect relationships that govern ozone and fine particle air quality in the Northeastern United States. The Center’s overall goal was to bring together a team of investigators from across the country to infuse state-of-the-science chemistry, physics, and numerical mathematics into models used to simulate particulate air quality, and then apply these models to two of the most important areas of the country from an air quality perspective: The South Coast Air Basin of California and the Northeastern United States.
Summary/Accomplishments (Outputs/Outcomes):Atmospheric models are the tools by which one assesses the effect of emissions changes on air quality. Such models are a mathematical embodiment of all that is known about the chemistry and physics relevant for species emitted into the atmosphere. The U.S. Clean Air Act specifies that atmospheric models are to be used when formulating Air Quality Management Plans. First developed in the 1970s, three-dimensional air quality models were initially focused on gas-phase species; a major goal was simulating urban/regional ozone formation. In the late 1980s and early 1990s, particulate matter (aerosols) was integrated into atmospheric models. During this 30-year period, models have evolved as more is learned about the chemistry and physics of the atmosphere.
Simulation of gas and particulate air quality at the urban and/or regional scale now represents an undertaking of enormous importance and complexity. To insure that future decisions about levels of emission control needed to meet ambient air quality standards are based on the best science possible, it is essential that the U.S. Environmental Protection Agency (EPA) foster continued development of the state-of-the-art of atmospheric models.
Each Principal Investigator brought unique interests to the project. Figure 1 shows a schematic of the building blocks of a comprehensive, three-dimensional urban/regional-scale gas/particulate atmospheric model, with application to the two regions noted. The figure indicates the areas to which each of the Principal Investigators directed his or her efforts. The project was characterized by a significant degree of collaboration among investigators to achieve the goals set forward in the original proposal.
Major achievements of the Center include:
· Significant improvements in atmospheric air quality models were accomplished in the areas of aerosol microphysics, chemistry, and numerical methods. These improvements have been transferred to the EPA’s Community Multi-scale Air Quality model.
· Advancements in the understanding of gas-phase reactions important in ozone and aerosol formation were achieved through both laboratory and theoretical research.
· Techniques for using single-particle mass spectrometry data in evaluating atmospheric models have been developed and tested.
· Emissions inventory procedures were advanced, and a national inventory of ammonia emissions was assembled.
· A better understanding of impacts of emissions on ozone and particulate air quality was accomplished for the South Coast Air Basin of California and the Northeastern United States.
