dc.description.abstractIn this work, Ansgrom exponent (a) and curvature (a2), skewness and kurtosis are used to give a clear particles size distribution. This is because some researchers reported the existence of negative curvatures for fine mode aerosols and near zero or positive curvatures are characteristic of size distributions with a dominant coarse-mode or bimodal distribution with coarse-mode aerosols having a significant relative magnitude. The aerosol types used in this work are Sahara and Urban aerosols that are extracted from Optical Properties of Aerosols and Clouds (OPAC4.0). From the results, it is discovered that a and skewness can be used to determine the main dominance particles size distributionin terms of number. The kurtosis can be used to determine the dominant particles in terms of volume. The a2 signifies whether the particle distribution is either monomodal or bimodal. It shows that when a2 is negative, it signifies monomodal distribution while when a2 is positive it signifies bimodal type of size distribution.
