Air Temperature and Black Carbon Concentration in the Surface Atmosphere at Tiksi, Yakutia

Abstract

Temporal variations of the black carbon (BC) concentration and air temperature measured in the surface atmosphere at the Tiksi Hydrometeorological Observatory (Yakutia) in May–September 2012–2018 have been analyzed. The average daily air temperature in July and August during the longest (1–2 days) episodes of abnormally high BC concentrations (greater than 1000 ng/m³) in comparison with the days outside these episodes can increase by 10–11°C (at an average temperature of around 9°C for these two months). However, the presence of one or two synchronous episodes of abnormally high values of both parameters within a month increases the average monthly air temperature by only 0.4–0.7°C (within the standard deviation of interannual variations) and can hardly lead to significant climatic effects for the region of observations.
