Based on four decades of research by Professor Andrew Goudie, this volume provides a
state-of-the-art synthesis of our understanding of desert geomorphology. It presents a truly …

The role of atmospheric parameters and aerosols in the transmission of COVID‐19 within
tropical Africa, especially during the harmattan season, has been under‐investigated in …

Dust generation and transportation from North Africa are thought to modulate the West
African Monsoon (WAM) features. In this study, we investigated the relationship between the …

A study of the long-term variability; trend and characteristics of visibility in four zones of
Nigeria was carried out. Visibility and other meteorological data from NOAA-NCDC and …

The uncertainty in the quantification of aerosol properties such as concentration, size, and
composition, spatially and temporally makes regional studies important. Therefore, this study …

The Harmattan, a dry, northeasterly trade wind, transports large quantities of Saharan dust
over the Sahelian region during the dry season (December–March). Studies have shown …

Harmattan is a season of dry, cold, dusty wind, and haze that is peculiar to West Africa. This
season and COVID-19 share common conditions such as malaise and respiratory issues …

The optical communication network is a laser-based technology technique that transmits
data through line-of-sight seamlessly. Free-Space Optics (FSO) based on optical technology …

The objective of this work is to analyze the temporal and spatial variability of the monthly
mean aerosol index (AI) obtained from the Total Ozone Mapping Spectrometer (TOMS) and …

The spatial and temporal variability, trend of visibility, frequency of occurrence (FOO) of 'thick
dust haze'(TDH) and of 'light dust haze'(LDH) during the Harmattan season (November to …
