Short summary
A 3-month field campaign was conducted in March–June 2015 in Senegal, as part of the SHADOW (SaHAran Dust Over West Africa) project. This article presents the time variability of the chemical composition of submicron particles. Organics (sulfates) were predominant for days under continental (marine) influence. Half the organic sources were identified as local, including one due to open waste-burning, and half were linked to regional air masses and enhanced photochemical processes.
