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

Written by Kevin Hodur for the 2015 Michigan Tech Research Magazine Deep in the eastern Atlantic, roughly 900 miles west of Portugal, lies the tiny island of Pico. On maps, it looks like nothing— hardly more than a pinpoint in a sea of blue. But to atmospheric researchers, the remote island’s towering Pico Mountain holds the key to understanding how aerosols

Aqueous Phase Secondary Organic Aerosol: Isoprene Oxidation Products and Cloud Processing Michigan Tech Research for Excellence Research Seed 2014 – 2016 Atmospheric aerosol particles and cloud droplets determine what fraction of solar radiation reaches the Earth’s surface and what fraction of it returns to space, thus reducing the warming potential of greenhouse gases. Aerosol particles exert a combination of effects

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

Building a Cloud Chamber for Collaborative Research

Cumulus_2

NSF MRI: Development of a Turbulent Cloud Chamber NSF Major Research Instrumentation Program, 2010-2013 (Extended to 2015) This effort will develop a laboratory cloud chamber to assess impacts of well-characterized turbulence (generated via Rayleigh-Benard convection) on cloud microphysics and aerosol processing. The cylindrical chamber will have a working volume of 3.14 m^3 and be capable of simulating a full range of

Research Project to Study Ambient Aerosol Composition

Storm Peak Laboratory above Steamboat Springs, CO

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
