英文摘要	Brown carbon (BrC) is a source of light-absorbing aerosols. The Arctic is more sensitive to emissions of light-absorbing aerosols than lower latitudes. Knowledge of BrC in a historical period is beneficial to understand its role in a changing climate. Here, we present measurement of water-soluble BrC (WS-BrC) for the Arctic aerosols during late winter-late spring in 1991. Mass absorption coefficient (0.07 +/- 0.04 M/m) and efficiency (0.41 +/- 0.21 m(2)/g) at 365 nm of WS-BrC were lower than those in polluted urban and rural regions. WS-BrC was mainly from biomass burning/combustion (dark winter to mid-March) and marine sources connected with photochemical gas to particle conversion (after polar sunrise to June). Solar radiative absorption of WS-BrC relative to elemental carbon was 5% on average in February to April and surged to 34% after mid-May. This study helps in understanding the role of BrC in the Arctic climate.
