Air Pollution Source Apportionment in a Coastal Transition Zone Using a Combination of Pollutant Monitoring Techniques During the OWLETS-2 Field Campaign
Abstract
Local and regional sources of gaseous and particulate air pollution observed on Hart-Miller Island East of Baltimore, MD in the Northern Chesapeake Bay were characterized using a combination of aerosol and gas-phase monitoring techniques. Observations took place during the 2018 Ozone Water-Land Environmental Transition Study (OWLETS-2) campaign between June 6th and July 6th. Instrumentation included TOLNet lidars, micro-pulse lidars, ceilometers, radiometers, Doppler wind lidars, ozonesondes, Pandora, AERONET, and a diverse set of in situ and mobile platforms (aircraft, ship, and Unmanned Aerial Vehicles) chemical (trace gas and particulate) measurements. Chemical source apportionment evaluation included principal component analysis followed by multi-linear regression analysis, stable carbon isotope analysis, stable isotope mixing model evaluations, emission ratio source evaluation, and air parcel back trajectory analysis. This technique enabled identification and characterization of major air pollution sources and source categories (e.g., electric generating units, waste incineration stations, landfill emissions, and ship emissions).
