Abstract:

Aerosol optical depth (AOD) retrieved by moderate resolution Imaging spectroradiometer (MODIS) sensor aboard NASA�??s satellite and also collected by aerosol robotic network (AERONET) site in Kuwait were studied. The diurnal behavior of the shape and magnitude of the volume size distribution (VSD) for fine and coarse particles have been studied during several dust events. Figure 1 displays the variation of VSD during four dust events. We see that the coarse particles increase substantially during the dust storm occurred on 24 May. The back trajectory model shows that the dust is transported from Syria and Iraq down to Kuwait. The current analysis considers the behavior of meteorological parameters during dusty days using the method of superposed epoch analysis. Air temperature decreases during dust events. This effect can be due to scattering of sunlight back to space by the suspended dust particles. A good correlation has been found between particular matter (PM10) concentrations and AOD.
