Mineral dust is generated from the ground surface by strong winds, and it transports long distance over the globe. In the process, cloud formation and absorption and scattering of solar radiation cause weather and climate changes. Also, when it deposits in the ocean, feeding nutrients by phytoplankton and promoting photosynthesis are enhanced. The deposition on snow and ice causes albedo change. This is known as the yellow dust (Asian dust, KOSA) phenomenon in Asia region including Japan. In order to understand dust behavior, integration in a wide range of academic areas is necessary.
In the emission process, the amount of dust changes greatly depending on the surface conditions in dryland area, and it is necessary to deal with broad areas such as soil, topography, vegetation, precipitation, desertification and soil deteriorations. In the transport process, we deal with areas such as weather, atmospheric aerosol, radiation. In the deposition process, we deal with areas such as ocean, snow ice, health to people and livestock. Drying and changes in vegetation also have social scientific aspects such as national policies, management of livestock, and population increase. In addition, dust and sand dunes are common phenomena not only in the Earth but also in other planets such as Mars and Saturn. In this way, it is difficult to understand the dust phenomenon only from one field, it is important for researchers in many areas to discuss and share information through this dust session, and advance exchange of researchers.
