Abstract

Harmattan intensity may be so great that visibility at ground level is reduced to less than a hundred meters by the dust clusters. The precipitations like snow, rain absorb and scatter electromagnetic energy leading to cancellation in its signal strength. In this paper, the records of ground level visibility during harmattan will be analyzed with respect to the approximated particle rate (or density) of harmattan. The specific particle attenuation possible on radio frequency signals during harmattan was analyzed, computed and plotted results obtained. The attenuation variations obtained indicates a significant loss in power during harmattan periods.

Keywords

harmattan, specific particle attenuation and radio frequency.
