20W: 20E, Lat 0: 30N) by its climatological and geographical conditions is a key region for
the characterization of global atmospheric aerosol optical properties. This study evaluates
the spatial and temporal variation of the Aerosol Optical Depth (AOD440nm), aerosol
particle size characterization (Angstrom exponent (α440-675nm) at four locations (Agoufou,
Banizoumbou, Cape Verde and Ilorin) over a period of January 2005 to December 2009 …
