Chemical mass size distributions of atmospheric aerosols over the atlantic ocean between europe and antarctica

摘要

Physical properties and chemical composition of atmospheric aerosol were measured in November-December 1999 over the Atlantic Ocean from the English Channel to the Antarctic coast,and in January 2000 at the Finnish Antarctic research station Aboa (73deg03'S,13deg25'W,470 m a.s.l).Koponen et al.(2002)presented number size distributions during the cruise and Virkkula et al.(2002)presented some results of the chemical analyses of the filter samples during the expedition.In addition to filter samples the size-segregated chemical composition of aerosol was studied using multi-stage impactors.The chemical mass size distributions of aerosols measured both on the cruise and at Aboa are presented.
