study evaluates the vertical profiles of aerosol and cloud optical properties
in 40 dominated dust and smoke regions in Western-Northern Africa (WNA) and
Central-Southern Africa (CSA), respectively, from the surface to 10km and from
2008 to 2011 based on LIVAS (LIdar climatology of Vertical Aerosol Structure
for space-based lidar simulation studies). Aerosol extinction (AE), aerosol
backscatter (AB), and aerosol depolarization (AD) generally increase from the
surface to 1.2 km and decrease from 1.2 km to the upper layers in both WNA and
CSA. AE and AB in CSA (maximum of 0.13 km<sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\">, 0.14 km</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\">,
