Abstract
The report presents the existing knowledge of combustion particles' impact on the climate in the Arctic and is prepared by an expert group under the Arctic Council's Arctic Monitoring and Assessment Programme (AMAP). The report focuses on soot particles (Black Carbon) but also treats other organic particles (Organic Carbon) which are emitted to the air from incomplete combustion. The aim of work was to make a status of the existing knowledge and to evaluate different sources and distribution and the emissions' importance to warming in the Arctic. Among the results are: a) BC (Black Carbon) deposited to Arctic snow and ice results in positive radiative forcing; b) BC deposited to Arctic snow and ice exerts a greater warming than the with-in Arctic direct atmospheric radiative forcing by BC; c) Climate models indicate that global direct atmospheric forcing due to BC leads to Arctic warming. Direct atmospheric forcing by BC that has been transported into the Arctic at high altitudes may have a relatively small impact on Arctic surface temperatures; d) OC (Organic Carbon) species that are co-emitted with BC and that reach the Arctic are unlikely to compensate for the positive readiative forcing due to BC and, over snow and
