Identification and characterization of dust sources using satellite observations and model simulations

Dust sources are mostly located in remote areas and satellite observations are very suitable for their identification. Different methods inferring active dust sources have been developed in the recent past, which roughly can be separated into direct (e.g., back-tracking of dust plumes to their place of origin) and indirect methods (e.g., frequency of high atmospheric dust loading). Thereby, the accuracy of the identification methods varies with the temporal and spatial resolutions and the ambiguities of the satellite dust retrieval used. In concert with satellite-based dust source characterization, model simulations allow for a holistic assessment on dust sources and their controlling mechanism - ultimately providing insight into the multifaceted nature of the atmospheric dust life-cycle.
