Short summary
Atmospheric aerosols were collected in Cotonou/traffic (CT), Benin, and, Abidjan/traffic (AT), Abidjan/landfill (AL) and Abidjan/domestic fires (ADF), Côte d'Ivoire, from February 2015 to March 2017. We report the weekly PM2.5, elemental (EC) and organic (OC) carbon, and aerosol optical depth (AOD) in both cities. PM2.5 was 32 ± 32, 32 ± 24, 28 ± 19 and 145 ± 69 µg m−3 at CT, AT, AL and ADF. OC / EC is 3.5 at CT, 2.0 at AT, 2.2 at AL and 5.2 at ADF. AOD is 0.58 at Cotonou and 0.68 at Abidjan.
