“…1). Sampling plots were located in the area adjacent to the ZOTTO Station (Heimann et al, 2017), the instrument cluster of which makes it possible to record the atmospheric signal at the origin of forest fires in the station area (Chi et al, 2013;Panov et al, 2015;Mikhailov et al, 2017) and affords the opportunity of linking the monitoring data of the atmospheric gas composition with ground-based measurements (Panov et al, 2016). The study area is characterized by high and extremely high combustibility.…”

Wildfires are the major cause of forest death in Siberia, as well as one of the main ecological factors forming biodiversity. Here, we present the impact of surface wildfires on Northern Eurasian boreal ecosystems with the example of the main tree species in the Near-Yenisei Siberia. The wildfire impact in the study area is determined by the mean annual burning rate of 0.20 ± 0.05%. In the extremely dry summer of 2012, this value increased to 19%. The integral fire radiative power through the season reached 4.1 × 10 5 MW/km 2 , whereas the mean annual value did not exceed 0.64 × 10 5 MW/km 2. Our observations demonstrate the highly variable effect of surface fires on conifer species in Siberia. Only trees with DBH > 5 cm survived a year after moderate severity surface fires. After high severity (usually steady) surface fires only pine trees with DBH > 17.2 cm survived, while trees with DBH > 18.1 cm were the most resistant within further post-fire succession.

Abstract. We present long-term (5-year) measurements of particulate matter with an upper diameter limit of ∼ 10 µm (PM 10 ), elemental carbon (EC), organic carbon (OC), and water-soluble organic carbon (WSOC) in aerosol filter samples collected at the Zotino Tall Tower Observatory in the middle-taiga subzone (Siberia). The data are complemented with carbon monoxide (CO) measurements. Air mass back trajectory analysis and satellite image analysis were used to characterise potential source regions and the transport pathway of haze plumes. Polluted and background periods were selected using a non-parametric statistical approach and analysed separately. In addition, near-pristine air masses were selected based on their EC concentrations being below the detection limit of our thermal-optical instrument. Over the entire sampling campaign, 75 and 48 % of air masses in winter and in summer, respectively, and 42 % in spring and fall are classified as polluted. The observed background concentrations of CO and EC showed a sine-like behaviour with a period of 365 ± 4 days, mostly due to different degrees of dilution and the removal of polluted air masses arriving at the Zotino Tall Tower Observatory (ZOTTO) from remote sources. Our analysis of the near-pristine conditions shows that the longest periods with clean air masses were observed in summer, with a frequency of 17 %, while in wintertime only 1 % can be classified as a clean. Against a background of low concentrations of CO, EC, and OC in the near-pristine summertime, it was possible to identify pollution plumes that most likely came from crude-oil production sites located in the oil-rich regions of Western Siberia. Overall, our analysis indicates that most of the time the Siberian region is impacted by atmospheric pollution arising from biomass burning and anthropogenic emissions. A relatively clean atmosphere can be observed mainly in summer, when polluted species are removed by precipitation and the aerosol burden returns to near-pristine conditions.
