Spatial variability of AERONET aerosol optical properties and satellite data in South Korea during NASA DRAGON-Asia campaign
We investigated spatial variability in aerosol optical properties, including aerosol optical depth (AOD), fine-mode fraction (FMF), and single scattering albedo (SSA), observed at 21 Aerosol Robotic Network (AERONET) sites and satellite remote sensing data in South Korea during the spring of 2012.

We investigated spatial variability in aerosol optical properties, including aerosol optical depth (AOD), fine-mode fraction (FMF), and single scattering albedo (SSA), observed at 21 Aerosol Robotic Network (AERONET) sites and satellite remote sensing data in South Korea during the spring of 2012.

The springtime particle air quality was characterized by high background aerosol levels and high contributions of coarse-mode aerosols to total aerosols.
