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 PM_2.5, elemental (EC) and organic (OC) carbon, and aerosol optical depth (AOD) in both cities. PM_2.5 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.
