Abstract
Description
Recurrent challenges of the theoretical estimation of aerosol optical thickness (AOT) are traceable to bogus
assumption in its mathematical model. The objective of this paper is to propound a model that could describe the
aerosol distribution sizes per time. The physics of the salient properties of aerosol within the Stokes regime was
discussed. The mathematical model was applied to six locations within 335 ˟ 230 Km2 area of a selected portion
of south-west, Nigeria. Though the climatic change is evident via thirteen years ground data set assimilation, the
sensitivity of the proposed model was proven to increase by 0.1%. The research affirmed the use of some
parameters (e.g. minimum temperature, cloud cover, relative humidity and rainfall) to estimate aerosol optical
thickness and by extension the aerosol distribution size over an area.
