The new data on the surface atmospheric black carbon (BC) concentration derived from continuous daily sampling during October 2017 - March 2018, that is, cold half year without wildfires as BC sources, in the remote area of Pechora-Ilych Nature Biosphere Reserve are analyzed. Average BC concentrations (with standard deviations) are equal to (296 ± 172) and (175 ± 82) ng/m3 for settlement Yaksha and in its neighborhood, respectively. Monthly average BC concentrations measured are compared with related monthly average satellite data ( A good agreement between them may be regarded as their inter-calibration and confirms the reliability of both result types. The analysis of air mass trajectories at the observation point shows the main anthropogenic BC sources to be situated at a distances of less than 500 km in industrial areas of the Central Urals, gas and oil production areas of Yamalo-Nenets and Khanty-Mansiysk Autonomous District, towns and settlements of Perm region, Udmurtia, and Komi Republic.
