Session Description:
Cities house the majority of Earth’s population and are major sources of emissions of reactive nitrogen, greenhouse gasses and heavy metals to the atmosphere. This juxtaposition has a disproportionate influence on global biogeochemical cycles and human health and well-being. Understanding and mitigating the impacts of these pollutants have been hampered by our coarse-grained national atmospheric monitoring networks that are designed to avoid local hotspots of emissions and deposition. This session focuses on emerging methods and approaches for monitoring local, near ground emissions, including fuel combustion and resuspension of particulates; approaches to correlate these methods with accepted reference standards; methods for quantifying risk to human health and ecosystem function; and the application of computational fluid dynamics, stable isotopes, and other approaches to identifying urban pollutant emissions and deposition hotspots.
