Short summary

This paper presents 4 years of total gaseous mercury data obtained from measurements made at the Cape Verde Atmospheric Observatory, a subtropical site in the Atlantic Ocean. The data show a clear decreasing trend in the overall concentrations but in air from sub-Saharan Africa the trend is less significant and the data more variable. We attribute this result to an influence from artisanal small-scale gold mining in this region, a source for which there is uncertain information.
