Abstract. 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.

Keywords: atmosphere, Arctic, Tiksi, black carbon, air temperature, temporal variations, climatic effect.
