A13M:
Mineral Dust Aerosols: From Small‐Scale Insights to Large‐Scale Understanding I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 16298

Session Description:
Interactions of the dust cycle with other components of the Earth system produce a wide range of complex effects on, for instance, atmospheric composition, human health, the hydrological cycle, climate, and ecosystems. To better understand and assess these effects, substantial advances are needed, including field and laboratory measurements, remote sensing techniques, and models of the physical and chemical properties of dust. This session invites contributions reporting any such advances, as well as studies addressing any aspect of the dust cycle and its impact on the Earth system. This includes the identification of dust source regions and variability within these, modeling of the dust cycle and its interactions with other cycles of the Earth system, investigations of dust interactions with clouds, radiation, precipitation, and the biosphere, quantification of effects of land use and climate changes on dust emissions, and understanding of dust impacts on air quality and human health.
