主 题：East Greenland Ice core Black carbon Seasonal variability Potential emission sources
摘 要：This study reports on the measurements of ion and refractory black carbon(rBC)concentrations in a shallow(10.96 m)ice core sample which was drilled from the field site of the East Greenland Ice Core Project(EGRIP)in July,*** results provide a recent record of rBC deposition in the East Greenland ice sheet from 1990 to *** annual variability in oxygen(δ^(18)O)and hydrogen(δD)isotopic compositions indicated that notably warm events occurred since *** in rBC occurred during summer seasons,which may be attributed to the burning of biomass in boreal *** rBC record and analysis of historical air trajectories using the HYSPLIT model indicated that anthropogenic BC emissions from Russia,North America and Europe contributed to the majority of rBC deposition in the Greenland region,and a reduction in anthropogenic BC consumption in these areas played a dominant role in the decrease in BC concentrations since *** record also suggests that the emissions from the East Asian region(China)contributed very little to the recorded BC concentrations in East Greenland ice *** model results indicated that radiative forcing due to BC had decreased significantly since 1990,and had remained below 0.02W m^(-2) since 2000.
