This workshop improved our knowledge of the research activities related to African dust transported into the Americas by engaging the scientific community involved in these activities.

The specific objectives of the workshop were:

  • To learn what is known in the Caribbean, South America, Central America, and southeastern USA regarding long-range transported African dust; chemical and physical characterization; optical properties; radiative effects; sampling and analysis; transport and deposition; heterogeneous reactions; health effects; impact on climate (cloud formation, precipitation, hurricane suppression), visibility, and ecosystem; rain chemistry; modeling; and lab studies.
  • To learn about the topics mentioned above related to long-range transported dust (not necessarily from Africa), but from results obtained for regions other than the Caribbean, South America, Central America, and southeastern USA.
  • To assess possible quality indexes for future references or uses.
  • To define the scientific questions that still need to be addressed in this area.
  • To discuss how to coordinate measurements and activities in the region in order to gain a better and more coherent understanding of the impacts of African dust across the region.
  • To promote collaborations among participants from a variety of countries impacted by and/or studying African dust in the Caribbean, southeastern USA, Central America and South America.
