This study is an area of growing importance in investigations of environmental issues associated with climate change, desertification, soil loss, and air quality. The overall goal of this research is to characterize dust emission dynamics in source areas (natural and anthropogenic soils) with high-resolution data of aeolian processes from field and lab experiments to develop a realistic model of the potential of dust quantities and types loading to the atmosphere. Primary outcomes are understanding the nature of dust emission, and parameterization for comprehensive prediction models. The main research tasks are characterized by cooperation between theoretical and experimental approaches. The dust experiments are conducted with the BGU wind-tunnels that generate high-resolution data (dust fluxes, masses and concentrations, PM10 and PM2.5, sediment-supply potential, aeolian connectivity). The relationships between topsoil properties and dust emissions will provide a better understanding of the impact of future environmental changes on dust sources and emissions.
