Аннотация:This work studiedemissionsof aerosol Black Carbon(BC)from an urban area in the Arctic region. This pollutant species has significant climate forcing potential at high latitudes. Three months of real time BC measurements were made at an isolated location4 km south-east ofSalekhardCity, on the Polar CircleinNorth-Western Siberia.Based onconditional probability function (CPF)analyses, wind directionsfrom the city were correlated withhigh BC concentrations, tens of times higher than the arctic backgroundobservednearby. According to official statisticaldata, diesel fuel and natural gas combustion are the primary sources ofemissionsin Salekhard. The diurnal BC trend identifies the significant impact of transport and heating emissions. In April-May, maximum BC concentrations of ~ 430 ng/m3were recorded in the urban emission. In July,during area-wide wildfires, concentrationsreached ~ 960 ng/m3;at this time the short-wavelength (470nm absorption) data exceededthe long-wavelength(880nm absorption)by a record value of ~ 260ng/m3.This result identifiesthe smoke plume contribution to the atmosphereloadingand deterioration of air quality inthe urban environment.
