Aerosol black carbon in the European Arctic: Measurements at Zeppelin station, www.atmos-chem-phys.net/12/6775/2012/ Atmos
[1] An aerosol black carbon (BC) data set from ongoing measurements at Zeppelin station (474 m asl), near Ny-Å lesund (10 m asl), Svalbard is reported for the period 1998 -2007. Annual average and median BC concentrations were 39 and 27 ng m À3 , respectively, while monthly averages ranged from a ma...

| Summary: | [1] An aerosol black carbon (BC) data set from ongoing measurements at Zeppelin station (474 m asl), near Ny-Å lesund (10 m asl), Svalbard is reported for the period 1998 -2007. Annual average and median BC concentrations were 39 and 27 ng m À3 , respectively, while monthly averages ranged from a maximum $80 ng m À3 in February/ March to a minimum 0 -10 ng m À3 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 (À9.5 ng m À3 per decade) for the period to 2007 has been observed which is, however, similar to the detection limit. |
