Impact of Canadian Wildfires 2023 on North Atlantics Region Air Quality: An Analysis Using ASDC Data

The escalating threat of wildfires in North America raises significant concerns regarding their adverse effects on air quality and public health, as recent wildfires have resulted in widespread smoke plumes that transcend international borders. This study focuses on the exposure of the North Atlantic region to smoke from Canadian wildfires, underscoring the profound implications for public health and environmental well-being. To assess the air quality impact, we analyze satellite data obtained from the NASA Atmospheric Science Data Center (ASDC) at Langley Research Center, in conjunction with ground-based measurements and atmospheric modeling outputs. Specifically, we investigate concentrations of atmospheric aerosols, notably PM2.5 particulate matter originating from Canadian wildfires, dispersion patterns, and the duration and intensity of smoke events affecting the North Atlantic. Utilizing data from multiple instruments including those from the Earth Polychromatic Imaging Camera (EPIC), the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOPLidar), and Measurement of Pollution in the Troposphere(MOPITT) strengthens the conclusions drawn from the impact assessment and estimation of aerosol loading. Ground-based measurements, including data from air quality monitoring stations, provide localized information for validation and calibration purposes.The study's findings enhance understanding of the repercussions of Canadian wildfires on air quality in the North Atlantic region, underscoring the necessity of monitoring and prediction of transboundary smoke events through the integration of data from diverse sources, such as those provided by the ASDC. This information is pivotal for policymakers, public health officials, and residents in affected areas to formulate effective strategies in mitigating health risks associated with wildfire smoke and improving air quality during wildfire seasons. The study emphasizes the critical role of atmospheric remote sensing, particularly the use of ASDC data, in addressing the challenges posed by wildfires and their consequences on regional scales.
