Аnnotation: Temporal variations of black carbon (BC) concentration and air temperature measured in the surface atmosphere in the Hydrometeorological Observatory Tiksi (Yakutia) in May-September, 2012-2018 were analyzed. Noticeable excesses in daily air temperature during the longest (1-2 days) episodes of abnormally high BC concentration (greater than 1000 ng/m3) in comparison with the days out of these episodes were registered during the warmest months (July and August). These effects are up to 10-11 degrees (where as the average temperature for these two months is about 9 °C). However, the presence of one or two synchronous episodes of abnormally high values of both parameters within a month changes monthly air temperature by only 0.4-0.7 °C (to be within the standard deviation of inter-annual variations) and may hardly produce significant climatic effect in the region.
