A21L:
Long-Range Transport of Dust and Pollution in the Past, Present, and Future I


Session ID#: 10697

Session Description:
With the changing land-use, land-cover and climate, dust storms have become more frequent. Dusts are produced from the desert regions of the world and are transported to long distances, affecting human health, transport industry (aviation), oceanic/terrestrial nutrient supplies, atmospheric and cloud properties. The track of dust storms can change quickly depending upon prevailing atmospheric and meteorological conditions. Thus, emission mechanisms of dust and their intercontinental transport have drawn large interests equally amongst the experimentalist and modelers. An early warning system of present day dust transport and transformation, and future climate feedback will help us alleviate large-scale damages and improve the utilization for biological productivity. 

We invite contributions related to dusts and their local, regional and global impacts on human  health, monsoons, clouds, hydrological cycle, ocean color/biology, atmospheric radiation, snow and glaciers.
