Abstract

Geographical distributions and seasonality patterns of major dust source areas were analysed in the paper by using the daily aerosol measurements of NASA’s Total Ozone Mapping Spectrometer (TOMS) between 1979 and 2011. Spatial investigations of aerosol maps have confirmed that major source areas can be connected to specific geomorphological environments of distinct arid-semiarid regions with recent pluvial history. Largest dust activity can be observed in the topographical lows of Saharan and Arabian deserts, and in the intermountain, endorheic basins of Central Asia fed by fine-grained material from the adjacent mountain belts. Dust emissions are associated to regional seasonal, meteorological conditions; with typically high dust activity in spring and summer. - (AM)
