China has implemented strict emission control measures, but it is unclear how they affect black carbon (BC) aging and light absorption. Here, we use the Community Atmosphere Model version 6 (CAM6) with four-mode of Modal Aerosol Module coupled machine learning (MAM4-ML) to simulate BC during 2011-2018 2050/2100 following a neutrality scenario (SSP1-2.6), respectively. During 2011-2018, mass ratio coatings (

Abstract Atmospheric soot and organic particles from fossil fuel combustion biomass burning modify Earth’s climate through their interactions with solar radiation modifications of cloud properties by acting as condensation nuclei ice nucleating particles. Recent advancements in understanding individual microscopic composition have led to heightened interest microphysical properties. This review article provides an overview current advanced measurements offers insights into future avenues for studying these To quantify morphology ageing, fractal dimension ( D f ) is a commonly employed quantitative metric which allows characterize morphologies aggregates relation ageing factors like internal mixing state, core-shell structures, phase, heterogeneity. Models been developed incorporate diversity metrics aged particles, enabling assessment optical absorption radiative forcing effects. The are complex they influenced particle sources, process, meteorological conditions. Furthermore, soluble exhibit diverse forms can engage liquid–liquid phase separation sulfate nitrate components. Primary carbonaceous such tar balls warrant further attention due strong light absorbing properties, presence toxic constituents, small size, impact human health. Future research needs include both atmospheric modeling approaches, focusing on changes the structures ensembles, effects dynamics

Atmospheric black carbon (BC) particles play an important role in air pollution, climate change, and human health. Evaluating BC's impacts by model simulation requires understanding of the distribution other aerosol species between those containing BC free during atmospheric aging process. Previous studies observed a large variability mass fraction BC-containing PM2.5 (FBC-containing), complicating determination their impacts. In this work, we conducted field observations various polluted environments across China for process-level FBC-containing. We find that FBC-containing, ranging from 10 to 90%, can be elucidated concept oxidation capacity (AOC). The contrast FBC-containing haze events is determined whether initial freshly emitted limited daytime AOC levels. quantify parametrize resolving under different conditions, indicating efficient formation secondary on when daytime-average concentrations Ox (i.e., O3 + NO2) exceed 80 μg m-3. Our study provides valuable insights into mixing state representations environments, facilitating accurate evaluation models.
