To identify the long-term trend of particle size variation, we analyzed aerosol optical depth (AOD, τ) separated as dust (τD) and coarse-(τPC) and fine-pollution particles (τPF) depending on emission sources and size. Ångström exponent values a

Black carbon (BC) absorption aerosol optical depth (AAODBC) defines the contribution of BC in light absorption and is retrievable using sun/sky radiometer measurements provided by Aerosol Robotic Network (AERONET) inversion products. In this study, w

Fine particulate matter (PM) release is regulated by environmental policies in most countries. This study investigated long–term trends in the mass extinction efficiency (Qe) of aerosols in Northeast Asia. For this purpose, the Qe was calculated us

The mass extinction efficiency(MEE), which indicates the degree of aerosol extinction(scatter and absorption) per unit PM mass concentration, is an important factor in converting optical concentration into mass concentration. Because its value varies

The refractive index (RI) of aerosol is an important parameter that reflects the scattering and absorption capacity of aerosol and is widely used in atmospheric models and remote sensing studies. It depends on several properties such as chemical spec

In the case of large industrial complexes, there are state management equipment to monitor pollutants emitted from chimneys, but there are undetected sources of pollution, such as leaks during processes, leaks from pipes, and leaks from unsealed ware
