Short summary

Aging of transported Saharan dust in the Caribbean was observed by electron microscopy, yielding size, chemical composition and mixing state for each individual particle. Models were developed for assessing mixing relevant for the atmosphere. Particles become internally mixed with sulfate during transport and sea salt in the Caribbean boundary layer. The mixing increases deposition velocity and dust cloud activation, and thus may impact on radiative and cloud nucleating properties.
