Observation bio-effect of SW-global solar radiation in Ilorin in the tropics

Surface Albedo Estimation and Variation Characteristics at a Tropical Station

“…This indicates about 40% of sunlight being reflected away back to space. This does indicate a period of little or no clouds to reflect radiation, little or no dust to scatter radiation back to space but enhances more sunlight reaching the ground surface; hence performance of solar energy devices is expected to be high, fruition of crops and plants to be enhanced and the Earth's surface temperature is expected to rise (Babatunde et al, 2009). …”

Evaluation of Residence Time of Dust Aerosols during the Harmattan Season in Sokoto Area of Northwestern Nigeria, Using Visibility Data

“…According to the facts established by many researchers, the harmattern haze, a natural atmospheric aerosol regime which affects most parts of West Africa including Nigeria has its origin in the Sahara desert in North East Africa. For instance Kalu [1], Prospero, [2],Babatunde et al [3] identify the alluvial plain of Bilma (18 o N, 12 0 E) in Southern Niger, and Largeau (18 0 N, 19 0 E), in Chad as the main sources of the dust which affects the greater parts of West Africa. Kalu [1] reported that during desert storms, large quantity of sand and dust are lifted into the atmosphere, transported by the North East trade winds and dispersed throughout West Africa from the month of November of one year to March of the following.…”

An Investigation on Effects of Harmattan Dust (aerosols) on Horizontal Visibility Deterioration over Bauchi, North- eastern Nigeria

“…In Bauchi, a town in North-eastern Nigeria, aerosols concentration due to harmattan is prevalent since other sources of aerosol such as emissions from industrial activities are limited. Harmattan season soil aerosols are mainly transported by the North Easterly Winds from the Bilma plain (18°N, 12°E) in Niger Republic and Faya Largeau (18°N, 19°E) in the Chad basin, particularly from the Bodele depression to different parts of West Africa [3][4][5][6][7][8].…”
