Challenges in understanding past and present eolian dust dynamics

Abstract

Dust Workshop 2011: Processes and Quaternary History of Dust Dynamics; Bremen, Germany, 31 October to 3 November 2011 Mineral dust is now generally recognized as a key element in global climate. However, many open questions need to be addressed to reduce the large uncertainties that still exist regarding the global dust cycle. The Atmospheric Dust During the Last Glacial Cycle: Observations and Modeling initiative (ADOM; see http://www.pages-igbp.org/workinggroups/adom) of the Past Global Changes (PAGES) tackles these questions from both modern and paleo perspectives. A 3-day workshop funded by PAGES and the Center for Marine Environmental Sciences (MARUM) in Germany brought together 50 international experts on marine, terrestrial, and polar dust archives; meteorology; remote sensing; and climate modeling. The workshop aimed to bridge gaps between disciplines and to cover all temporal and spatial scales involved in dust processes.
