For this purpose, appropriate thresholds for AOD&lt;inf&gt;500&lt;/inf&gt; and α&lt;inf&gt;340-1020&lt;/inf&gt; are applied. It is shown that a single aerosol type in a given location over the AS can exist only under specific conditions while the presence of mixed aerosols is the usual situation. Analysis indicates that the dominant aerosol types change significantly in the different regions (coastal, middle, and far) of AS. Thus the urban/industrial aerosols are mainly observed in coastal AS, the desert dust particles occur in the middle and northern AS, while clear maritime conditions mainly occur in far AS. Spectral AOD and Ångström exponent data were analyzed to obtain information about the adequacy of the simple use of the Ångström exponent and spectral variation of a for characterizing the aerosols. Using the least squares method, α is calculated in the spectral interval 340-1020 nm along with the coefficients a&lt;inf&gt;1&lt;/inf&gt; and a&lt;inf&gt;2&lt;/inf&gt; of the second-order polynomial fit to the plotted logarithm of AOD versus the logarithm of wavelength. The results show that the spectral curvature can effectively be used as a tool for their discrimination, since the fine mode aerosols exhibit negative curvature, while the coarse mode particles exhibit positive curvature. The correlation between the coefficients a&lt;inf&gt;1&lt;/inf&gt; and a&lt;inf&gt;2&lt;/inf&gt; with the Ångström exponent, and the atmospheric turbidity, is further investigated.
