Аnnotation: Black carbon (BC) concentration measured in near surface air on the remote from sources territory of the Pechora-Ilych State Natural Biosphere Reserve, located on the western side of the Northern Ural mountains is presented for two years (December 2017 - November 2019). The temporal variations in BC concentration through a year and the location of its main sources are analyzed. The average values for two cold and two warm half-years were 128 and 62 ng/m3, respectively. The measured BC concentration in near surface atmosphere was compared with MERRA-2 reanalysis data. On monthly scale, the anomalous increase in BC concentration during short-term smoke aerosol transport across the observation area is more clearly revealed from the reanalysis data, rather than by measured values at a single point. Daily monitoring allows us to detect the specific dates of such situations.
