Arctic Air Pollution is an edited collection of papers, first presented at a conference held at the Scott Polar Research institute in Cambridge in From December to April, the Arctic air mass is polluted by man-made mid-latitudinal emissions from fossil fuel combustion, smelting and industrial processes. In the rest of the year, pollution levels are much lower. This is the outcome of less efficient pollutant removal processes and better south (S) to north (N) transport during by: Air currents transport pollution into the Arctic. The strong cooling around the North Pole in winter causes warm polluted air from lower latitudes to slide over the cold air so that the pollution is not deposited in the Arctic. This is called the arctic dome, because cold air forms a . Jen Murphy, University of Toronto, Canada (IGAC Liaison) Fostering collaborative, interdisciplinary research on Arctic air pollution and its interactions with the Earth system and human societies. PACES is an IGAC-sponsored initiative, which aims to review existing knowledge and foster new research on the sources and fate of Arctic air pollution, its impacts on climate, health, and ecosystems, on the feedbacks between pollution .
Even though early Arctic explorers had noticed atmospheric haze and dirty deposits on the snow (), the remote Arctic atmosphere was long believed to be extremely r, pilots flying over the North American Arctic in the s observed widespread haze that could be seen every winter and early took until the s for scientists to realize that the haze was air pollution. Arctic air pollution includes harmful trace gases (e.g. tropospheric ozone) and particles (e.g. black carbon, sulphate) and toxic substances (e.g. polycyclic aromatic hydrocarbons) that can be transported to the Arctic from emission sources located far outside the region, or emitted within the Arctic from activities including shipping, power production, and other industrial activities. Air pollution in the Arctic can have adverse effects on climate, ecosystems and health. Whilst air pollutants originate primarily from mid-latitude anthropogenic emission regions in Asia, Europe and North America or from boreal or agricultural fires (Law et al. ), sources of local pollution are already known to be important but their emissions and impacts are poorly quantified. Scientists studying air pollution that blankets millions of square miles in the Arctic report it was much heavier than they had expected this winter, raising concern about its effect on the world.
Local Arctic air pollution can be severe and signiﬁcantly exceed air quality standards, impairing public health and affecting ecosystems. Speciﬁcally in the wintertime, pollution can accumulate under inversion layers. However, neither the contributing emission sources are well identiﬁed and. This collection of papers on Arctic haze or air pollution analyzes the sources in southern industrialized areas, the nature and extent of pollutants, meteorological phenomena, effects on snow and ice, and possible climatic change. On the other hand, Arctic air pollution affects GCC by perturbing the radiative budget of the Arctic by solar radiation absorption and scattering by aerosols and by the deposition of light-absorbing aerosols on snow or ice that decrease the surface albedo. For these reasons, Arctic air pollution is a hot topic the scientific community.
