Natural and Anthropogenic Aerosols in Arctic Areas

Abstract

Some properties, sources and effects of natural and anthropogenic atmospheric aerosols in Arctic areas are discussed in this paper. Long-range transport of anthropogenic aerosols, and local biochemical sources that are thought to lead to aerosol formation and growth are also discussed. Current knowledge and questions remaining to be answered clearly indicate that the future research and measurements of atmospheric aerosols are needed in the Arctic. An important issue is to reduce the uncertainties in assessments of the impact of climate change.
