A005:
Advances in Identification and Modeling of Dust Sources: Approaches and Accuracy from the Ground up to Space-Based Sensors





Session ID#: 25254

Session Description:
Earth system models underscore the vulnerability in the 21st century to extreme droughts, with probable heightened eolian activity. However, uncertainties remain regarding the magnitude and source of dust particles as our planet warms; a critical parameter for understanding changes in precipitation. A greater frequency of drought conditions may result in magnitude increases in atmospheric dust loads in urban areas and globally, which will increase risks of mortality from cardiorespiratory and dust-borne viral diseases. Thus, understanding the spatial and temporal variability in dust generation for both contemporary and historic landscapes will provide needed parameterization to better understand variability of atmosphere-land interactions and public health implications. This session will focus discussion from an inter-disciplinary perspective about our evolving knowledge of the linkages between drought, "natural" and anthropogenic dust emissivity globally.
