摘 要：Environmental quality and climate change are major challenges facing our nation and the worldwith current and potential impacts in the near and distant future. Fundamental understanding of atmospheric processes and coupling between the atmosphere, oceans, and biosphere are needed to understand and predict the interactions between climate and environmental processes and energy production practices. This is critical for providing policy makers with accurate information needed to develop cost-effective strategies to monitor, control, mitigate, and adapt to a changing climate. Reducing uncertainties in key components necessary to understand the Earth's complex climate and environmental systems is an important scientific objective, as discussed in National Research Council and National Science Foundation reports and embraced by the Climate and Environmental Sciences Division (CESD) within the Department of Energy's Office of Biological and Environmental Research (DOE-BER). The Environmental Molecular Sciences Laboratory (EMSL), a DOE scientific user facility located in Richland, Washington, encourages and enables molecular-level research that leads to discovery and innovation which enhances the quality of life, now and for generations to come. Because of the growing recognition of atmospheric aerosol chemistry impacts on climate change, regional pollution, and weather patterns, EMSL conducted a Science Theme Advisory Panel (STAP) workshop focused on atmospheric aerosol chemistry. Thirty-eight scientists from 11 institutions participated in the workshop held on January 30, 2013. Workshop participants were asked to evaluate areas where understanding the chemical details and time evolution of aerosol formation and development, as well as their chemical and physical properties, could have the largest impact on the development of reliable process-level understanding of regional and global atmospheric climate models.
