Dust in a changing climate: from small‐scale insights to large‐scale understanding

Session ID#: 72722

Session Description:
Interactions of the dust cycle with components of the changing Earth system produce a wide range of complex effects on, for instance, atmospheric composition, the hydrological cycle, climate, and ecosystems. To better understand and assess these effects, advances are needed in field and laboratory measurements, remote sensing techniques, and models of dust properties. This session invites studies reporting such advances, and results relevant to the NASA Earth Surface Mineral Dust Source Investigation, EMIT, are particularly encouraged. In addition, this session invites studies addressing the dust cycle and its impact on the Earth system. This includes studies of dust source regions, high latitude dust, dust interactions with clouds, radiation, precipitation, the cryosphere, and the biosphere, observational and modeling insights into the variability of dust on different time scales and climate feedbacks, dust impacts on air quality, and modeling studies of the dust cycle and its interactions with other Earth system cycles.
