Аннотация: Siberian boreal forest fires burn large areas annually, resulting in smoke that release large amounts of particulate emission into the atmospere. We sampled aerosol emissions from experimental fires of three Scots pine (Pinus sylvestris L.) forest sites of central Siberia. Emissions from ground-based aerosol samples were 0.1-0.7 t/ha. This value represented 1%- 7% of the total biomass (10-30 t/ha) consumed during the experimental fires. We were able classify the chemical composition of 77%-90% of the mass of particulate the emissions. Chemical analysis indicated that an average of 8%-17% of the particulate composition was of mineral emission.

Аннотация: The increasing of burning area in Siberia, the extension of fire season and fires intensity lead to significant carbon emission. One of the important tasks is to describe the spread of smoke aerosol and other combustion products using actual meteorological data and fire state information. A smoke aerosol covers territory hundreds times larger than the burning area and has an effect on forming the cloud and sediment formation exactly above the fire zone.

Аннотация: Siberia is currenly poorly represented in the system of global atmospheric observations. The lack of surface-based observations concerns the properties of atmospheric aerosol particles especially with respect to potential climate change. Here we report the first statistical analysis of the four years data observations at the ZOTTO observatory in Central Siberia aimed to assess the representative integral particle, seasonal variations of the aerosol, and possible sources of aerosol over the large Siberian forest area.

Аннотация: This paper analyses aerosol particle number size distributions, particulate absorption at 570 nm wavelength and carbon monoxide (CO) measured between September 2006 and January 2010 at heights of 50 and 300 m at the Zotino Tall Tower Facility (ZOTTO) in Siberia (60.8 degrees N; 89.35 degrees E). Average number, surface and volume concentrations are broadly comparable to former studies covering shorter observation periods. Fits of multiple lognormal distributions yielded three maxima in probability distribution of geometric mean diameters in the Aitken and accumulation size range and a possible secondary maximum in the nucleation size range below 25 nm. The seasonal cycle of particulate absorption shows maximum concentrations in high winter (December) and minimum concentrations in mid-summer (July). The 90th percentile, however, indicates a secondary maximum in July/August that is likely related to forest fires. The strongly combustion derived CO shows a single winter maximum and a late summer minimum, albeit with a considerably smaller seasonal swing than the particle data due to its longer atmospheric lifetime. Total volume and even more so total number show a more complex seasonal variation with maxima in winter, spring, and summer. A cluster analysis of back trajectories and vertical profiles of the pseudo-potential temperature yielded ten clusters with three levels of particle number concentration: Low concentrations in Arctic air masses (400-500 cm(-3)), mid-level concentrations for zonally advected air masses from westerly directions between 55 degrees and 65 degrees N (600-800 cm(-3)), and high concentrations for air masses advected from the belt of industrial and population centers in Siberia and Kazakhstan (1200 cm(-3)). The observational data is representative for large parts of the troposphere over Siberia and might be particularly useful for the validation of global aerosol transport models.

Аннотация: This report describes a unique setup for aerosol measurements at the new long-term Tall Tower monitoring facility near Zotino, Siberia (ZOTTO). Through two inlets at 50 and 300 m aerosol particle number size distributions are measured since September 2006 in the size range 15-835 nanometer dry diameter. Until the end of May 2007 total number (N(300)) concentrations at 300 m height ranged between 400 cm(-3) (5%) and 4000 cm(-3) (95%) with a median of 1200 cm(-3), which is rather high for a nearly uninhabited boreal forest region during the low productivity period of the year. Fitting 1-h average distributions with a maximum of four lognormal functions yielded frequent ultrafine modes below 20 nm at 50 m height than at 300 m, whereas the latter height more frequently showed an aged nucleation mode near 30 nm. The positions of Aitken (approximate to 80 nm) and accumulation modes (approximate to 210 nm) were very similar at both inlet heights, the very sharp latter one being the most frequent of all modes. The encouraging first results let us expect exciting new findings during the summer period with frequent forest fires and secondary particle sources from vegetation emissions.

Аннотация: The results of the SRXFA determination of the multielement composition of aerosols forming on fires in the boreal forests of Siberia are given. A comparison of the multielement composition of aerosols in the convective column of large forest fires and smoke plumes of surface fires with that of atmospheric aerosols of the Siberian region shows that the mass concentration of all analyzed elements exceeds the background values upon fires. A substantial change is observed in the quantitative composition of the aerosols. (C) 2001 Elsevier Science B.V. All rights reserved.

Аннотация: Siberia is one of few continental regions in the Northern Hemisphere where the atmosphere may sometimes approach pristine background conditions. We present the time series of aerosol and carbon monoxide (CO) measurements between September 2006 and December 2011 at the Zotino Tall Tower Observatory (ZOTTO) in Central Siberia (61° N; 89° E). We investigate the seasonal, weekly and diurnal variations of aerosol properties (including absorption and scattering coefficients and derived parameters, such as equivalent black carbon (BC e), Angstrom exponent, single scattering albedo, and backscattering ratio) and the CO mixing ratios. Criteria were established to distinguish polluted from near-pristine air masses, providing quantitative characteristics for each type. Depending on the season, 23-36% of the sampling time at ZOTTO was found to be representative of a clean atmosphere. The summer pristine data indicate that primary biogenic and secondary organic aerosol formation are quite strong particle sources in the Siberian taiga. The summer seasons 2007-2008 were dominated by an Aitken mode around 80 nm size, whereas the summer 2009 with prevailing easterly winds produced particles in the accumulation mode around 200 nm size. We found these differences to be mainly related to air temperature, through its effect on the production rates of biogenic volatile organic compounds (VOC) precursor gases. In winter, the particle size distribution peaked at 160 nm, and the footprint of clean background air was characteristic for aged particles from anthropogenic sources at great distances from ZOTTO and diluted biofuel burning emissions from domestic heating. The wintertime polluted air originates mainly from large cities south and southwest of the site; these particles have a dominant mode around 100 nm, and the ?BCe/?CO ratio of 7-11 ng m -3 ppb-1 suggests dominant contributions from coal and biofuel burning for heating. During summer, anthropogenic emissions are the dominant contributor to the pollution particles at ZOTTO, while only 12% of the polluted events are classified as biomass-burning-dominated, but then often associated with extremely high CO concentrations and aerosol absorption coefficients. Two biomass-burning case studies revealed different ΔBCe/?CO ratios from different fire types, with the agricultural fires in April?2008 yielding a very high ratio of 21 ng m -3 ppb-1. Overall, we find that anthropogenic sources dominate the aerosol population at ZOTTO most of the time, even during nominally clean episodes in winter, and that near-pristine conditions are encountered only in the growing season and then only episodically. © Author(s) 2013.

Аннотация: Reconstruction of climate change in Central Asia over the last millennium with an annual resolution was made using geochemical and biological proxy in lake bottom sediments and tree-ring data. We investigated the lake in Central Asia- Teletskoe (Altai), Kucherla (Altai), Baikal, Arahlei (Chita) - and adjacent areas. Cores of bottom sediments were investigated by method of scanning X-ray fluorescent analysis with synchrotron radiation with the spatial resolution of 0.1 mm. It corresponds to the time resolution ~ 0.2-0.5 year. At each point analyzed more than 30 trace elements from K to U. Geochemical proxy of terrigenous, organogenous and aerosol components of sediments well correlated with regional meteodata for the last 100-150 years. Time series of lithological-geochemical indicators of climate change based on dating by 14C, 137Cs and 210Pb was calibrated by instrumental hydrometeorological data. We used tree-ring series together with element contents as an additional proxy for calculation of transfer function, considering that tree-ring series are response to summer temperature in this climatic zone. Annual temperature and precipitation change for the Central Asia region (0 - 1000 years ago) have been reconstructed using the transfer functions such as: time series proxy=function (temperature, precipitation).

Аннотация: An assessment of atmospheric aerosol composition in middle and high latitudes of Eurasia has been made by integrating long-term (longer than five years) instrumental observations of microphysical and optical characteristics of atmospheric aerosols at the Zotino Tall Tower Observatory (ZOTTO) in the middle-taiga subzone of Yenisei Siberia and Lagrangian trajectory modeling. A correlative analysis of the findings and data for anthropogenic and forest fire emissions revealed signals existing in its formation, and their origin was assessed. © 2015, Pleiades Publishing, Ltd.

Аннотация: The results of 2-year (2010-2012) measurements of the concentrations of organic carbon (OC) and elemental carbon (EC), which were taken at the Zotino Tall Tower Observatory (ZOTTO) Siberian background station (61A degrees N, 89A degrees E), are given. Despite the fact that this station is located far from populated areas and industrial zones, the concentrations of OC and EC in the atmosphere over boreal forests in central Siberia significantly exceed their background values. In winter and fall, high concentrations of atmospheric carbonaceous aerosol particles are caused by the long-range transport (similar to 1000 km) of air masses that accumulate pollutants from large cities located in both southern and southwestern regions of Siberia. In spring and summer, the pollution level is also high due to regional forest fires and agricultural burning in the steppe zone of western Siberia in the Russian-Kazakh border region. Background concentrations of carbonaceous aerosol particles were observed within relatively short time intervals whose total duration was no more than 20% of the entire observation period. In summer, variations in the background concentrations of OC closely correlated with air temperature, which implies that the biogenic sources of organic-particle formation are dominating.

Аннотация: Summer 2012 was one of the extreme wildfire years in Siberia. At the surface air monitoring station "ZOTTO" (60°48'N, 89°21'E, 114 m a.s.l.) in Central Siberia we observed biomass burning (BB) influence on the ongoing atmospheric measurements within more than 50 % of the time in June-July 2012 that indicates a 30 times greater wildfire signal compared to previously reported ordinary biomass burning signature for the study area. While previous studies thoroughly estimated a relative input of BB into aerosol composition (i.e. size distribution, physical and optical parameters etc.) at ZOTTO, in this paper we characterize the source apportionment of the smoke aerosols with molecular tracer techniques from large-scale wildfires occurred in 2012 in the two prevailing types of Central Siberian ecosystems: complexes of pine forests and bogs and dark coniferous forests. Wildfires in the selected ecosystems are highly differed by their combustion phase (flaming/smoldering), the type of fire (crown/ground), biomass fuel, and nature of soil that greatly determines the smoke particle composition. Anhydrosugars (levoglucosan and its isomers) and lignin phenols taken as indicators of the sources and the state of particulate matter (PM) inputs in the specific fire plumes were used as powerful tools to compare wildfires in different environmental conditions and follow the role and contribution of different sources of terrestrial organic matter in the transport of BB pollutants into the pristine atmosphere of boreal zone in Central Siberia. © Published under licence by IOP Publishing Ltd.

Аннотация: Aerosols produced by wildfires are a common phenomenon in boreal regions. For the Siberian taiga, it is still an open question if the effects of aerosols on atmospheric conditions increase net CO2 uptake or photosynthesis. We investigated the factors controlling forest net ecosystem productivity (NEP) and explored how clouds and smoke modulate radiation as a major factor controlling NEP during fire events in the years 2012 and 2013. To characterize the underlying mechanisms of the NEP response to environmental drivers, Artificial Neural Networks (ANNs) were trained by eddy covariance flux measurements nearby the Zotino Tall Tower Observatory (ZOTTO). Total photosynthetically active radiation, vapour pressure deficit, and diffuse fraction explain at about 54-58% of NEP variability. NEP shows a strong negative sensitivity to VPD, and a small positive to f(dlf). A strong diffuse radiation fertilization effect does not exist at ZOTTO forest due to the combined effects of low light intensity, sparse canopy and low leaf area index. Results suggests that light intensity and canopy structure are important factors of the overall diffuse radiation fertilization effect.

Аннотация: Aerosol particle number size distributions (PNSD) were investigated to verify, if extremely low-volatility organic vapors (ELVOC) from natural sources alone could induce new particle formation and growth events over the remote boreal forest region of Siberia, hundreds of kilometers away from significant anthropogenic sources. We re-evaluated observations determined at a height of 300 m of the remote observatory ZOTTO (Zotino Tall Tower Observatory, http://www.zottoproject.org). We found that new particle formation events occurred only on 11 days in a 3-year period, suggesting that homogeneous nucleation with a subsequent condensational growth could not be the major process, maintaining the particle number concentration in the planetary boundary layer of the remote boreal forest area of Siberia. © 2018 Elsevier Ltd

Аннотация: 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 x 10(5) MW/km(2), whereas the mean annual value did not exceed 0.64 x 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.

Аннотация: Ежегодно на территории Сибири возникают сотни лесных пожаров. В последние десятилетия наблюдается увеличение их числа и площади соответственно, возрастает объем пирогенных эмиссий. При горении выделяются газоаэрозольные эмиссии, объем которых определяется интенсивностью пожара и сгоревшими лесными горючими материалами. В работе приведены расчеты эмиссии парниковых газов при лесных пожарах в светлохвойных насаждениях Нижнего Приангарья за 2014-2019 гг. С использованием данных о количестве сгорающих при пожаре лесных горючих материалов рассчитана масса парниковых газов, выделяющихся во время пожаров в зависимости от их вида, типа леса и метеоусловий, влияющих на высыхание горючих материалов. Установлено, что при пожарах в светлохвойных насаждениях она составляет от 5.9 до 37.5 т/га в зависимости от вида пожара и типа леса. Ежегодно в светлохвойных насаждениях Нижнего Приангарья этот показатель варьирует от 160 до 5649 тыс. т, в среднем более 2300 тыс. т. Всего за рассматриваемый период по расчетным данным выделилось при лесных пожарах более 16 млн т парниковых газов, с преобладанием СО-СО2. Выявлено, что неблагоприятные условия рассеивания эмиссий от лесных пожаров складываются в летние месяцы, характеризующиеся высокой повторяемостью штилей, приземных инверсий и радиационных туманов. Относительно благоприятные погодные условия при наличии факторов загрязнения по самоочищению атмосферы от пожарных эмиссий наблюдаются весной и осенью, когда регистрируется наибольшее количество ветреных дней
Every year, hundreds of forest fires occur on the territory of the Siberia. It is established that in recent decades there has been an increase in the number and area of forest fires, respectively, the volume of pyrogenic emissions increases too. During fires gas-aerosol emissions are released the volume of which is determined by the intensity of the fire and the burnt forest combustible materials. The paper presents calculations of greenhouse gas emissions from fires in light coniferous forests of the Lower Angara region for 2014-2019. Using data on the amount of forest combustible materials burned in a fire, the mass of greenhouse gases released during fires is calculated, depending on the type of fire, the type of forest and weather conditions that affect the drying of combustible materials., The estimated greenhouse gas emission from fires in light coniferous forests ranges from 5.9 to 37.5 ton/ha, depending on the type of fire and the type of forest. Each year, in the light coniferous forests of the Lower Angara region, greenhouse gas emissions from fires vary from 160 to 5649 thousand tons, on average more than 2300 thousand ton/ha per year. In total, during the period under review, according to the calculated data, more than 16 million tons of greenhouse gases were released during forest fires, with a predominance of CO-CO2. It is revealed that unfavorable conditions of dispersion of emissions from forest fires are formed in the summer months, characterized by a high frequency of calm, surface inversions and radiation fogs. Relatively favorable weather conditions in the presence of pollution factors for self-cleaning the atmosphere from fire emissions are observed in spring and autumn, when the greatest number of windy days is recorded.
