Mineral dust aerosols influence global climate by changing Earth’s radiative balance, influencing cloud formations, and by providing micronutrients to marine and terrestrial ecosystems. Recent studies focusing on the current climate have highlighted the importance of the chemistry, mineralogy and size distribution of the dust particles for quantifying the impact of dust onto climate and biogeochemistry. Although much progress has been made in global dust modeling, significant differences persist among various models and between model output and observations.
In this session we want to discuss ways to improve our global knowledge on dust characteristics, simulations and impact on the Earth, including radiative forcing, atmospheric chemistry, and biogeochemistry. We invite contributions focusing on dust reconstructions from climate archives as well as modern observations and model simulations, echoing the goals of the PAGES working group DICE (Dust Impacts on Climate and Environment). We particularly welcome talks that address how to transfer knowledge from the observational community to the model community and vice-versa.
