New Collaborative Research Project to Study Particulate Organic Nitrogen

Collaborative Research: Nitrogren Partitioning and Evolution of Particulate Organic Nitrogen in Peat Fire Emissions. NSF Atmospheric Chemistry Program, 2015-2017 Overview: This project aims to provide an insight into the partitioning and evolution of nitrogen (N) containing compounds emitted from combustion of peat soils (also referred to as organic soils). The two main objectives are: 1) to evaluate the partitioning of

Collaborative Research Project to Study Long-range Transported Aerosols

Collaborative Research: Chemical, Physical, and Radiative Properties of North Atlantic Free Tropospheric Aerosol after Long-range Transport NSF Atmospheric Chemistry Program, 2011-2014 The radiative forcing of aerosol is not determined solely by local sources and fresh emissions, but also by changes in the microphysical and chemical properties with atmospheric transformation. The composition of continental pollution outflow is altered by mixing, an

Research Project to Study Ambient Aerosol Composition

Collaborative Research: Hygroscopic Properties of Aerosol Organics NSF Atmospheric Chemistry Program, 2009-2012 Aerosols affect the Earth’s radiation balance directly by scattering sunlight and indirectly through their role as cloud condensation nuclei (CCN). An increase in the number of CCN leads to more numerous but smaller cloud droplets and increased cloud albedo. Current estimates of direct and indirect effects, -0.9 to
