Harmattan dust deposition in northern Nigeria

Naturevolume 286pages587588 (1980) | Download Citation



Studies of atmospheric dust deposits originating from Africa, within Atlantic Ocean sediments1,2, have provided useful indirect information on Quaternary environments, but dust studies in Africa are rare. Here Harmattan dust deposition measurements at Kano, northern Nigeria during the 1978–79 season are reported. A relation between dust deposition, visibility, solar radiation and wind speed is defined, which deteriorates during the latter half of the Harmattan season. A probable explanation of this deterioration is the local re-mobilization of existing dust.
