"Observing Neighborhood-Level Air Pollution Inequality from Space" with Sally Pusede, University of Virginia.
Urban air pollution and climate change disproportionately harm communities of color and low-income communities in the U.S. Air quality can vary substantially within cities; however, we have historically lacked spatially comprehensive observations that resolve air pollution differences at neighborhood scales. Recent and forthcoming satellites offer new opportunities to describe and inform decision-making related to neighborhood-level air pollution inequalities. These satellite measurements also provide temporal information useful for identifying the driving emission sources and situating inequalities in regional air quality and climate contexts. In this talk, I will discuss work advancing application of satellite remote sensing for observing neighborhood-scale air pollution inequalities and improving our understanding of their emission sources, chemistry, and variability with climate change. I will discuss avenues and barriers for the future, with satellite measurements having the potential to transform the demands people can place on their policymakers.
Sally Pusede is an associate professor in the Department of Environmental Science at University of Virginia. She is an atmospheric chemist with broad interests in air quality, climate, and atmosphere-biosphere interactions. Her research group makes measurements at the Earth’s surface and from onboard aircraft in diverse locations, including polluted cities, agricultural areas, and within forest canopies. Their focus is on the role of reactive nitrogen in chemical oxidation mechanisms and emissions of the greenhouse gas nitrous oxide. They utilize spatial and temporal variability in our datasets to derive mechanistic insight into processes taking place in urban and human-influenced environments. They work to find solutions to atmospheric problems that adversely affect human health and ecosystems.
