Air Pollution by Black Carbon in the Region of Wrangel Island: Comparison of Eurasian and American Sources and Their Contributions

Black carbon (BC) pollution in the region of Wrangel Island is significantly influenced by both Eurasian and North American sources. A study analyzing atmospheric transport data from 2015 to 2017 revealed that BC emissions during summer months originate predominantly from anthropogenic activities and wildfires in northeastern Eurasia and northwestern North America. The research utilized the HYSPLIT model for air mass trajectory calculations and a simplified BC transport model based on emission sensitivity functions, with data sourced from global databases like EDGAR and GFAS. The findings highlight the interannual variations in BC emissions, emphasizing the complex interplay between natural wildfires and human-induced pollution sources across these regions.
