Long Term Dust Aerosol Production from Natural Sources in Iceland

摘要

Dust affects the ecosystems over much of Iceland. The severity and frequency of dust events in Northeast Iceland are comparable to many of the major dust areas of the world. There is great interannual and decadal variability in the frequency of the dust events. The most active periods were the 1950s and the period from the early 1990s until 2008. The study indicates that Icelandic dust may be a non-negligible source for not only local, but also larger scale air pollution in the Arctic.
