报告了1998-2007年期间斯瓦尔巴特群岛靠近NY-Alesund(10米ASL)的齐柏林飞艇站(474m ASL)正在进行的测量得出的气溶胶黑碳(BC)数据。全年平均浓度和中位数分别为39和27 ng m(-3)，而月平均值则由2/3月的最高值80 ng m(-3)至6月至9月的最低0至10 ng m(-3)不等。BC浓度通过元素碳热光学分析进行了校准。PSCF轨迹分析表明，齐柏林飞艇的BC浓度主要受俄罗斯北部和中部来源地区的影响。自2001年以来，观察到2007年期间BC浓度有小幅下降趋势(每十年-9.5 ng m(-3))，但与检测下限相似。引用：Eleftheriadis，K.，S.Vratolis和S.Nyeki(2009)，欧洲北极的气溶胶黑碳：1998年至2007年在斯瓦尔巴特群岛的齐柏林飞艇站的测量，地球物理。研究报告，36，L02809，DOI：10.1029/2008GL035741。
An aerosol black carbon (BC) data set from ongoing measurements at Zeppelin station (474 m asl), near Ny-Alesund (10 m asl), Svalbard is reported for the period 1998-2007. Annual average and median BC concentrations were 39 and 27 ng m(-3), respectively, while monthly averages ranged from a maximum similar to 80 ng m(-3) in February/March to a minimum 0-10 ng m(-3) from June to September. BC concentrations were calibrated by elemental carbon thermo-optical analysis. PSCF trajectory analysis indicated that BC concentrations at Zeppelin were mainly influenced by source regions in northern and central Russia. Since 2001, a small decreasing trend in BC concentration (-9.5 ng m(-3) per decade) for the period to 2007 has been observed which is, however, similar to the detection limit.
