The Murphy research group makes novel field measurements with cutting edge instrumentation that advance the science of atmospheric chemistry, aerosols, and climate. Measurements are made from our groups’ mobile laboratory and from airborne platforms. The group has two focus areas: 1.) Absorbing Aerosols and 2.) Methane and volatile organic compound (VOC) Emissions from Energy Development. Black carbon and other absorbing aerosols are thought to be the third most important post-industrial warming agent in atmosphere after carbon dioxide and methane. Despite this, there remains significant uncertainty regarding the magnitude of absorbing aerosol emissions and optical properties. Our groups’ field measurements reduce these uncertainties. Methane and VOC emissions from oil and gas extraction are significantly larger than inventory estimates and impact climate and air quality. Our group quantifies fluxes of these species and identifies ways to reduce fugitive emissions.
