Black carbon (BC) aerosols emitted from biomass, fossil fuel, and waste combustion contribute to the radiation budget imbalance are transported over extensive distances in Earth’s atmosphere. These undergo physical chemical modifications with co-existing (e.g., nitrate, sulfate, ammonium) through aging processes during long-range transport primarily removed troposphere by wet deposition. Using precipitation samples collected North America between 26 October 1 December 2020 National Atmospheric Deposition Program (NADP), we investigated relationships BC both water-soluble ions organic (WSOC) using Spearman’s rank coefficients. We then attempted identify sources of deposition factor analysis (FA) satellite data fire smoke. showed a very strong correlation nitrate (ρ = 0.83). Strong correlations were also found WSOC, ammonium, calcium, sulfate 0.78, 0.74, 0.67, respectively). FA that was same as indicating could originate secondary aerosol formation biomass burning. Supported smoke, other correlated pollutants believed be associated wildfire outbreaks several states United States (US) November 2020.

Abstract Black carbon (BC) and brown (BrC) are light‐absorbing aerosols with significant climate impacts, but their absorption properties direct radiative effect (DRE) remain uncertain. We simulated BC BrC during the intense Canadian boreal wildfires in June 2023 using an enhanced version of CHIMERE chemical transport model. The study focused on a domain extending from North America to Eastern Europe, including Arctic up 85°N. model includes update treatment for enhancement aging scheme accounting browning blanching through oxidation. Validation against Aerosol Robotic Network satellite data showed accurately reproduced aerosol optical depth (AOD) at multiple wavelengths, both near wildfire sources transoceanic Europe. Improvements were observed simulations absorbing AOD (absorbing optical) compared baseline Significant enhancements achieved capturing spatial distribution areas affected by emissions. For 2023, regional all‐sky DRE attributed was reduced −2.1 W/m 2 control −1.9 This corresponded additional warming +0.2 (+10%) due advanced absorption. These results indicate importance accurate modeling predictions, large‐scale biomass burning events. They also highlight potential overestimations cooling effects traditional models, emphasizing need improved parameterization better simulate evaluating impacts mitigation strategies.
