Optimization of an Algorithm Using Aerosol Optical Properties to Investigate the Influence of Biomass Burning on an Urban Atmosphere (BC) 2 2021 Field Campaign

摘要: Biomass burning (BB) releases large quantities of fine particulate matter and gas phase-pollutants, including ozone precursors, which can undergo long-range transport and influence urban air quality. Due to the complex mixing of aged smoke and urban pollutants, it can be difficult to study the composition and influence of biomass burning on urban atmospheres. To address this problem, the Black and Brown Carbon aerosol optical study (BC2) is in its third year of development and utilizes a combination of real-time aerosol optical measurements, offline filter analysis, back trajectory analysis, and smoke plume modeling at multiple urban sites in Houston and El Paso, TX. The (BC) 2 sites are equipped with two tri-color absorption photometers (TAP), one three-wavelength nephelometer, and additional site characterization instrumentation, including a carbon monoxide analyzer and automated high-volume sampler …
