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: In this study we present the analysis of meteorological data obtained during 2 years of measurements at ZOTTO observatory. It was found that continental polar air dominates in study area and results in the strong radiation cooling in winter time. The microclimatic features showed the continental conditions in the region. The wind rose demonstrated South-East wind direction as dominating which could be associated with influence of the Siberian High. Due to relatively high homogeneity of landscape in study region the analyzed data set of meteorological variables is valid for the tall tower footprint and will be used for further study of GHG's behavior over Central Siberian forest ecosystems.

Аннотация: This paper studies the structure and dynamics of the major pools of organic matter in clearings in the lichen pine forests of the middle taiga subzone of Yenisei Siberia, in the range of measurements of the international observatory Zotto, a high-tech research platform for long-term ( 30 years) monitoring of the atmosphere and climate changes. The contribution of phytocenoses at different stages of post-clearing succession in the process of deposition of atmospheric carbon is analyzed. In conjunction with the data on atmospheric measurements of a wide range of greenhouse gases carried out at the base of the observatory, the results of this work will be used for modeling the stocks and flows of carbon in forest ecosystems of Central Siberia.

Аннотация: We present first results from 19 months of semicontinuous concentration measurements of biogeochemical trace gases (CO2, CO, and CH4) and O-2, measured at the Zotino Tall Tower Observatory (ZOTTO) in the boreal forest of central Siberia. We estimated CO2 and O2 seasonal cycle amplitudes of 26.6 ppm and 134 per meg, respectively. An observed west-east gradient of about -7 ppm (in July 2006) between Shetland Islands, Scotland, and ZOTTO reflects summertime continental uptake of CO2 and is consistent with regional modeling studies. We found the oceanic component of the O-2 seasonal amplitude (Atmospheric Potential Oxygen, or APO) to be 51 per meg, significantly smaller than the 95 per meg observed at Shetlands, illustrating a strong attenuation of the oceanic O-2 signal in the continental interior. Comparison with the Tracer Model 3 (TM3) atmospheric transport model showed good agreement with the observed phasing and seasonal amplitude in CO2; however, the model exhibited greater O-2 (43 per meg, 32%) and smaller APO (9 per meg, 18%) amplitudes. This seeming inconsistency in model comparisons between O-2 and APO appears to be the result of phasing differences in land and ocean signals observed at ZOTTO, where ocean signals have a significant lag. In the first 2 months of measurements on the fully constructed tower (November and December 2006), we observed several events with clear vertical concentration gradients in all measured species except CO. During "cold events'' (below -30 degrees C) in November 2006, we observed large vertical gradients in CO2 (up to 22 ppm), suggesting a strong local source. The same pattern was observed in CH4 concentrations for the same events. Diurnal vertical CO2 gradients in April to May 2007 gave estimates for average nighttime respiration fluxes of 0.04 +/- 0.02 mol C m(-2) d(-1), consistent with earlier eddy covariance measurements in 1999-2000 in the vicinity of the tower.

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: The results of measurements of ground CO2 concentration in the middle taiga subzone of the Yenisei region of Siberia (the ZOTTO observatory) in 2009 to 2012 are presented. Specific features of CO2 variability over the altitude profile up to 301 m are accounted for by specific diurnal and seasonal features in the functioning of terrestrial ecosystems as well as by atmospheric processes. It has been shown that the significance of regional and global components increases with elevation, while the contribution of the underlying surface in the region of the observatory decreases. The observed gradient differences between CO2 concentrations recorded at the onset and at the end of the cold period are explained by seasonal changes in the height of the atmospheric boundary layer. Comparison of data obtained at the ZOTTO observatory and at monitoring stations in Canada and the North Atlantic has shown that general trends in the seasonal variability of CO2 are similar and that specific features of the processes under study are dependent on biogeographic characteristics of the study regions.

Аннотация: Annually resolved and millennium-long reconstructions of large-scale temperature variability are primarily composed of tree ring width (TRW) chronologies. Changes in ring width, however, have recently been shown to bias the ratio between low- and high-frequency signals. To overcome limitations in capturing the full spectrum of past temperature variability, we present a network of 15 maximum latewood density (MXD) chronologies distributed across the Northern Hemisphere extratropics. Independent subsets of continental-scale records consistently reveal high MXD before 1580 and after 1910, with below average values between these periods. Reconstructed extratropical summer temperatures reflect not only these long-term trends but also distinct cooling pulses after large volcanic eruptions. In contrast to TRW-dominated reconstructions, this MXD-based record indicates a delayed onset of the Little Ice Age by almost two centuries. The reduced memory inherent in MXD is likely responsible for the rapid recovery from volcanic-induced cooling in the fourteenth century and the continuation of warmer temperatures until ~1600. ©2015.

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: Climatic changes during the first half of the Common Era have been suggested to play a role in societal reorganizations in Europe and Asia. In particular, the sixth century coincides with rising and falling civilizations, pandemics, human migration and political turmoil. Our understanding of the magnitude and spatial extent as well as the possible causes and concurrences of climate change during this period is, however, still limited. Here we use tree-ring chronologies from the Russian Altai and European Alps to reconstruct summer temperatures over the past two millennia. We find an unprecedented, long-lasting and spatially synchronized cooling following a cluster of large volcanic eruptions in 536, 540 and 547 AD (ref.), which was probably sustained by ocean and sea-ice feedbacks, as well as a solar minimum. We thus identify the interval from 536 to about 660 AD as the Late Antique Little Ice Age. Spanning most of the Northern Hemisphere, we suggest that this cold phase be considered as an additional environmental factor contributing to the establishment of the Justinian plague, transformation of the eastern Roman Empire and collapse of the Sasanian Empire, movements out of the Asian steppe and Arabian Peninsula, spread of Slavic-speaking peoples and political upheavals in China. © 2016 Macmillan Publishers Limited.

Аннотация: Organic matter pool and its distribution between growing stock, dead wood and windfall in upland and lowland Pinus sibirica dominated forests of Central Siberia (along the Yenisei River) is evaluated. The average growing stock is changing with advancing age from 163.9 ± 20.4 to 295.4 m3 ha-1 thus reaching its maximum in the mature forests (337.0 ± 19.6 m3 ha-1). According to the data collected, stock variation coefficient numbers display acceptable (growing stock: 14-28%) and high variability (windfall and dead wood: 63-85%). Windfall prevails in the structure of coarse woody debris (CWD) from 130.8 ± 18.5 to 171.7 ± 20.1 m3 ha-1, with the stocks greatly exceeding the amount of growing wood stock in middle-aged and declining stands in 1.4 and 2.1 times, respectively. The observations comply with common trend of deterioration of dark coniferous forests in Siberia. © 2015 by Forest Research Institute.

Аннотация: The article discusses the methods of satellite image classification to determine general types of forest ecosystems, as well as the long-term monitoring of ecosystems changes using satellite imagery of medium spatial resolution and the daily data of space monitoring of active fires. The area of interest of this work is 100 km footprint of the Zotino Tall Tower Observatory (ZOTTO), located near the Zotino settlement, Krasnoyarsk region. The study area is located in the middle taiga subzone of Western Siberia, are presented by the left and right banks of the Yenisei river. For Landsat satellite imagery supervised classification by the maximum likelihood method was made using ground-based studies over the last fifteen years. The results are the identification of the 10 aggregated classes of land surface and composition of the study area thematic map. Operational satellite monitoring and analysis of spatial information about ecosystem in the 100-kilometer footprint of the ZOTTO tall tower allows to monitor the dynamics of forest disturbance by fire and logging over a long time period and to estimate changes in forest ecosystems of the study area. Data on the number and area of fires detected in the study region for the 2000-2014 received in the work. Calculations show that active fires have burned more than a quarter of the footprint area over the study period. Fires have a significant impact on the redistribution of classes of land surface. Area of all types of vegetation ecosystems declined dramatically under the influence of fires, whereas industrial logging does not impact seriously on it. The results obtained in our work indicate the highest occurrence of fires for lichen forest types within study region, probably due to their high natural fire danger, which is consistent with other studies. The least damage the fire caused to the wetland ecosystem due to high content of moisture and the presence of a large number of fire breaks in the form of open water. © 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: The interannual variations in the characteristics of the seasonal cycle (annual and seasonal amplitudes, winter emission, dates of annual minimum and maximum, and phase) and in the growth rate of atmospheric carbon dioxide concentration over Central Siberia are analyzed for the period from May 2009 to January 2016. The results are based on the continuous monitoring of CO2 concentration at the Zotino Tall Tower Observatory (ZOTTO, www.zottoproject.org). It is found that the seasonal amplitude of CO2 concentration in the atmo spheric surface layer over Western Siberia is 26.4 ± 0.8 ?mol/mol (no long-term trend toward its increase was revealed), the annual mean growth rate of CO2 is 2.34 ?mol/mol per year, its variations range from 1 to 4 ?mol/mol per year. © 2018, Allerton Press, Inc.

Аннотация: Though the extraction of increment cores is common practice in tree-ring research, there is no standard for the number of samples per tree, or trees per site needed to accurately describe the common growth pattern of a discrete population of trees over space and time. Tree-ring chronologies composed of living, subfossil and archaeological material often combine an uneven distribution of increment cores and disc samples. The effects of taking one or two cores per tree, or even the inclusion of multiple radii measurements from entire discs, on chronology development and quality remain unreported. Here, we present four new larch (Larix cajanderi Mayr) ring width chronologies from the same 20 trees in northeastern Siberia that have been independently developed using different combinations of core and disc samples. Our experiment reveals: i) sawing is much faster than coring, with the latter not always hitting the pith; ii) the disc-based chronology contains fewer locally absent rings, extends further back in time and exhibits more growth coherency; iii) although the sampling design has little impact on the overall chronology behaviour, lower frequency information is more robustly obtained from the disc measurements that also tend to reflect a slightly stronger temperature signal. In quantifying the influence of sampling strategy on the quality of tree-ring width chronologies, and their suitability for climate reconstructions, this study provides useful insights for optimizing fieldwork campaigns, as well as for developing composite chronologies from different wood sources. © 2018 Elsevier GmbH

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: Одним из важнейших вопросов в атмосферных исследованиях содержания парниковых газов является определение территории (футпринта), оказывающей влияние на их концентрации, регистрируемые на высотных мачтах. Выявление суммарного сезонного футпринта (зона влияния) для концентраций парниковых газов, непрерывно измеряемых на мачте обсерватории ZOTTO высотой 301 м за вегетационный период (май-сентябрь) с 2008 по 2012 г. (за исключением 2011 г.), было выполнено на основе стохастической транспортной модели STILT. Результаты показали, что сезонный футпринт для обсерватории ZOTTO за четыре исследуемых года превысил 6,9 ⋅ 10 6 км 2 , а 75 %-й футпринт варьировал от 1,9 до 2,3 ⋅ 10 6 км 2 . Для этого же периода с помощью данных спутникового картографирования расти тельного покрова России (Russian Land Cover, по данным MODIS за 2014 г.) было выявлено, что в сезонном 75 %-м футпринте наибольшую площадь занимают болота, а затем (по убыванию) лиственничники, смешанные леса, светлохвойные вечнозеленые леса, лиственные леса, тундра, темнохвойные вечнозеленые леса, луга и остальные классы. При этом анализ вкладов индивидуальных ячеек, составляющих футпринт, показал, что в большей степени на формирование концентраций парниковых газов, регистрируемых на высотной мачте ZOTTO, влияют типы растительности в непосредственной близости к мачте, а именно болота, смешанные леса, светлохвойные и темнохвойные насаждения
A crucial issue in atmospheric studies on greenhouse gas content involves assessing the representativeness (footprint) having influence on their concentrations measured by tall towers. In this study, the Stochastic Time-Inverted Lagrangian Transport (STILT) model was used to estimate seasonal cumulative footprint climatology for greenhouse gases measurements obtained on the 301-meter-high Zotino Tall Tower Observation Facility (ZOTTO) for the growing seasons (May-September) from 2008 to 2012 (with the exception of 2011). Results showed that the ZOTTO seasonal concentration cumulative footprint climatology for four years reached 6.9×10 6 km 2 and the 75 % cumulative footprints varied from 1,9 to 2,3×10 6 km 2 . For the same period, the Russian Land Cover map based on MODIS data for 2014 was used to estimate the impact of land cover surrounding the ZOTTO tower on concentration measurements. The analysis showed that in the 75 % seasonal cumulative footprint the largest area is occupied by bogs, followed (in decreasing order) by larch, mixed, light-coniferous evergreen forests, grassland, and by other classes. Furthermore, analysis of the contributions from individual cells making up a footprint showed that the largest influ ence on formation of greenhouse gas concentrations as recorded by ZOTTO comes from the types of vegetation growing in the immediate vicinity of the tall tower, namely bogs, mixed forests, and light and dark coniferous forest stands

Аннотация: Vast carbon reservoirs hosted in the Arctic realm may trigger a significant positive feedback loop in the global Earth climate system under existing global warming scenarios. Nevertheless, sparse coverage of the Arctic region with greenhouse gas (GHG) observation network limits our understanding of carbon cycling in this environment and making predictions about a fate of carbon conserved in currently frozen ground. Especially critical gaps exist in the vast Arctic territories of Siberia, where solely 3 continuous atmospheric carbon observation stations are currently operational and located entirely in Northeastern Siberia: Atmospheric carbon observation station Ambarchik (69.62° N, 162.30° E), the Tiksi hydrometeorological observatory (71.6°N, 128.9° E) and the Cape Baranova ice base observatory on the Bolshevik Island, Severnaya Zemlya (79.3° N, 101.8° E). In this paper we introduce a newly established coastal atmospheric carbon observation station Dikson (73.33° N, 80.34° E), jointly maintained by the V. N. Sukachev Institute of Forest SB RAS (Krasnoyarsk, Russia), Joint Directorate of Taimyr Nature Reserves (Norilsk, Russia) and the Max Planck Institute for Biogeochemistry (Jena, Germany), which is intended to fill the gap in the atmospheric GHG observations in the northcentral Siberian domain. The general west wind drift expected at the location of the site makes it more sensitive to the northern latitudes of Western Siberia, as compared to the other, more eastern, stations, which, due to the specific cyclonic activity that prevents air from the Icelandic low pressure minimum spreading towards the east of Severnaya Zemlya. The measurement site, which was launched in September 2018, is located on the Taimyr Peninsula near the gulf of the Yenisei River at the coast of the Kara Sea. Atmospheric mole fractions of CO2, CH4 and H2O at the station are continuously measured by an analyzer based on the cavity ring-down spectroscopy (CRDS) technique (G2301-f, Picarro Inc., USA). Data quality control of trace gas measurements is achieved by regular calibrations against WMO-traceable reference gases, an applied water vapor correction and meteorological records that permit data screening. A preliminary wind analysis and calculated backward trajectories from hot spots downwind of the measurement site reveal that during late spring and summer tundra landscapes of the upper part of the Taimyr Peninsula, the gulf of the Yenisei River and the adjacent shelf areas of the Arctic Ocean are the major contributors to the observed variability at the station. Conversely in winter (frost period) this site becomes receptive to air masses originated in the continental domain and containing the anthropogenic GHGs, e.g. the gas production on the Tazovskiy Peninsula. Here we summarize the scientific rationale of the new site, give technical details of the instrumental setup, analyze the local environments and present some exemplary results. © SGEM2019.
