Exposure to ambient black carbon derived from a unique inventory and high-resolution model

Significance In this study, we have developed a unique global black carbon (BC) emission inventory using a 10-km grid based on the latest source and emission factor information. The inventory is used to model BC concentrations using a global atmospheric aerosol climate model, with a high-resolution grid for Asia, to better resolve the exposure of populations to elevated BC concentration. The model with even higher resolution (10 km) is used for the North China Plain. Finally, the population exposure concentrations are evaluated.
