The Treatment of Particle Size and Coating Amount in Model Simulations and Aerosol Processes Treated

Caption

Panel a: Many model simulations were made by changing particle sizes at emissions (e.g., 'Small size' and 'Large size'). The 'Detailed method' can simulate various coating states of BC particles (pure BC, thinly-coated BC, thickly-coated BC etc.). The 'Simple method', which is similar to the method used in many previous modeling studies, cannot resolve different coating states of BC particles sufficiently. Panel b: Aerosol processes in the atmosphere (emissions, transport, transformation, and deposition processes) and their impact on BC heating effect are simulated in the global aerosol model.
