“…For these reasons, observations from satellite remote sensing have been carried out to investigate aerosol properties at regional and global scale, including aerosol optical depth (AOD) (e.g., Curier et al, 2008;Levy et al, 2007;Torres et al, 2007;Ahn et al, 2014;Veefkind et al, 1999;Zhang et al, 2011), fine-mode fraction (FMF) or Ångström exponent (AE) (e.g., Jones and Christopher, 2007;Lee et al, 2010;Nakajima and Higurashi, 1998;Remer et al, 2008), single scattering albedo (SSA) (e.g., Dubovik et al, 2002;Levy et al, 2007;Jeong and Hsu, 2008;Torres et al, 1998Torres et al, , 2005Torres et al, , 2007Jethva et al, 2014), and aerosol types (e.g., Higurashi and Nakajima, 2002;Kim et al, 2007;Lee et al, 2010). This information was further utilized to estimate radiative forcing of aerosol (e.g., Christopher et al, 2006;Chung et al, …”
