Nuclear explosion -- Seismic profile -- Siberian craton -- Upper mantle

Аннотация: The upper-mantle structure was studied from first-arrival data along the Meteorite profile, run using underground nuclear explosions. Unlike the layered, slightly inhomogeneous models in the previous works, emphasis was laid on lateral inhomogeneity at the minimum possible number of abrupt seismic boundaries. We used forward ray tracing of the traveltimes of refracted and overcritical reflected waves. The model obtained is characterized by considerable velocity variations, from 7.7 km/s in the Baikal Rift Zone to 8.0-8.45 km/s beneath the Tunguska syneclise. A layer of increased velocity (up to 8.5-8.6 km/s), 30-80 km thick, is distinguished at the base of seismic lithosphere. The depth of the layer top varies from 120 km in the northern Siberian craton to 210 km in its southeastern framing. It has been shown that, with crustal density anomalies excluded, the reduced gravity field is consistent with the upper-mantle velocity model. В© 2013.

    Spatial and temporal anomalies of chlorophyll concentration in Atlantic ocean (by space-based data)
/ A. Shevyrgonov, G. Vysotskaya, E. Shevyrgonov // Advances in Space Research. - 2002. - Vol. 30, Is. 11. - P. 2541-2546, DOI 10.1016/S0273-1177(02)80334-9 . - ISSN 0273-1177
Аннотация: The work presents long-standing CZCS-satellite-based data about spatial distribution of anomalies in chlorophyll concentration and temperature of the ocean. An anomaly criterion is proposed. Maps of Atlantic ocean areas with elevated probability of anomalies are given. Properties of anomalous zones in different parts of the Atlantic ocean are discussed. Satellite-based maps of anomaly coefficients for chlorophyll concentration and temperature in the Atlantic ocean have been shown to feature substantial differences, the zones of elevated anomaly of chlorophyll concentration and temperature - to be close only in the vicinity of the Amazon outflow into the Atlantic ocean. Along with fundamental knowledge about dynamics of biological phenomena in the ocean the methods described may be used to reveal deviations due to anthropogenic impact. The methods presented may be used to process SeaWiFS prograna data. The data derived may be used to analyze long-standing time series to estimate randomness of cunent changes. В©2002 COSPAR.

    Spatial and temporal anomalies of sea surface temperature in global scale (by space-based data)
/ A. Shevyrnogov, G. Vysotskaya, E. Shevyrnogov // Advances in Space Research. - 2004. - Vol. 33, Is. 7. - P. 1179-1183, DOI 10.1016/S0273-1177(03)00369-7 . - ISSN 0273-1177
Аннотация: The work presents the data on the spatial distribution of temperature anomalies in the Global Ocean, based on the long-term measurements with the AVHRR satellite equipment. It is noteworthy that such results can be only obtained by using long time series of satellite images. To obtain them by ship-borne methods is actually impossible. The proposed anomaly criterion is equal to a difference between minimum/maximum and average temperature, normed for the mean square deviation. The difference is calculated from the whole time series (with regard to a season). Based on this criterion, anomalies can be distinguished on the background of usual seasonal dynamics at various absolute values of deviations of the measured parameter. Besides, rare, single, fluctuations can be also revealed. Based on the proposed criterion, connected zones have been defined. These zones occur almost in every part of the Global Ocean. The data obtained have been analyzed in association with the CZCS (1978-1986) and SeaWiFS satellite images in order to compare them with the areas of anomalous dynamics of chlorophyll concentration and the regions quasistationary in the seasonal dynamics of chlorophyll. Anomalies in the temperature dynamics are of exceptional importance for the formation of climatic deviations; they affect the ocean-atmosphere interaction and reflect variations in the hydrological structure of the surface waters. The work presents a comparison with the dynamics of chlorophyll concentration distribution determined from the SeaWiFS data for the Atlantic Ocean. В© 2003 COSPAR. Published by Elsevier Ltd.

    Trends of chlorophyll concentration in the surface layer of the Northern and Central Atlantic, a satellite data-based study

Аннотация: The new data on anomalies in seasonal dynamics of chlorophyll concentration in the ocean have altered the approach to the analysis of long-term trends of phytopigments in the surface layer of the ocean. Zones have been found in which at various times there was a many-fold increase in chlorophyll concentration versus its usual level. These changes are local in time and space. If anomalies in the long-term tendencies in the change of phytopigment surface distribution in the ocean are ignored in the analysis, the resulting picture will inadequately reflect the real processes. The work presents the results of the analysis of long-term trends of chlorophyll concentration on the basis of the CZCS satellite data in the Atlantic Ocean. The results are given as maps representing different variants of trends. The data obtained can be used to analyze the consequences of long-term changes of climate and changes in the interaction between the atmosphere and the ocean. В©2002 COSPAR.

    Hidden staircase signal in recent climate dynamic

Climate shifts -- ENSO variability -- pause in global warming

Аннотация: In this study we used HadCRUT4 monthly mean near surface temperature anomalies for 1950–2014 years in order to investigate properties of recent warming. Our aim was to separate changes produced by short-term natural variations and to look on temporal and spatial dynamics of residual temperature anomalies. For this we subtract linear influence of El Nino Southern Oscillation from each grid box of surface temperature measurements. We found that residual global temperature dynamics looks like staircase function: linear trends for three quasi-stable periods 1950–1987, 1988–1997 and 1998–2014 are near zero and near all warming occurred during two shifts of 1987/1988 and 1997/1998 years. Examples of similar staircase behavior of some climate parameters were found in NCEP/NCAR and NASA MERRA reanalysis data. Staircase signal suggests the existence of some regulation mechanism in climate system. This mechanism should maintain global temperature adjusted for El Nino Southern Oscillation near stable in 1950–1987, 1988–1997 and 1998–2014 periods nevertheless all the time growing forcing due to anthropogenic greenhouse gases. © 2015, Korean Meteorological Society and Springer Science+Business Media Dordrecht.

    On the ultraviolet anomalies of the WASP-12 and HD 189733 systems: Trojan satellites as a plasma source
/ K. G. Kislyakova [et al.] // Mon. Not. R. Astron. Soc. - 2016. - Vol. 461, Is. 1. - P988-999, DOI 10.1093/mnras/stw1110 . - ISSN 0035-8711
Аннотация: We suggest an additional possible plasma source to explain part of the phenomena observed for the transiting hot Jupiters WASP-12b and HD 189733b in their ultraviolet (UV) light curves. In the proposed scenario, material outgasses from the molten surface of Trojan satellites on tadpole orbits near the Lagrange points L4 and L5. We show that the temperature at the orbital location of WASP-12b is high enough to melt the surface of rocky bodies and to form shallow lava oceans on them. In case of WASP-12b, this leads to the release of elements such as Mg and Ca, which are expected to surround the system. The predicted Mg and Ca outgassing rates from two Io-sizedWASP-12b Trojans are ?2.2 ? 1027 s-1 and ?2.2 ? 1026 s-1, respectively. Trojan outgassing can lead to the apparent lack of emission in Mg II h&k and Ca II H&K line cores of WASP-12. For HD 189733b, the mechanism is only marginally possible due to the lower temperature. This may be one of the reasons that could not explain the early ingress of HD 189733b observed in the far-UV C II doublet due to absence of carbon within elements outgassed by molten lava. We investigate the long-term stability region of WASP-12b and HD 189733b in case of planar and inclined motion of these satellites and show that unlike the classical exomoons orbiting the planet, Io-sized Trojans can be stable for the whole systems lifetime. © 2016 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

    «Лестница» потепления с середины 20 века

   Перевод заглавия: A staircase signal in the warming of the mid-20th century

Аннотация: Regime-shift like structures in decadal climate change have been detected in many studies of temperature and related climatic variables by (Yasunaka and Hanawa 2002; Chavez et al. 2003; Lo and Hsu 2010; Reid and Beaugrand, 2012; Jones , 2012; Reid et al., 2016; Jones and Ricketts, 2017). Much attention has been given to a pause in warming (hiatus) during 1998-2014 (Tollefson 2014). We recently suggested and applied a simple method to adjust HadCRUT4 surface temperature anomalies for ENSO effects (Belolipetsky et al. 2015; Bartsev et al. 2016; Bartsev et al. 2017). After this adjustment for major ENSO and volcanic effects the hiatus is even more pronounced. Moreover, we observed similar quasi-stable periods during 1950-1987 and 1988-1997 and almost all the warming occurred during the ~1987 and ~1997 shifts. It should be mentioned that a similar shift has likely occurred in 2015-2016, but this issue is outside the scope of this short paper. Here we want to demonstrate the reality of the staircase pattern using different measurements and climate parameters. We analyzed several global datasets: HadCRUT v4.5 - land and sea surface temperature (SST) anomalies; ICOADS v2.5 - SST anomalies measured from ships; NCEP OI v2 - SST measured by satellite instruments; UAH MSU v5.6 and RSS MSUv3.3 - two satellite datasets measuring temperature of the lower troposphere (TLT). The ENSO signal was removed by empirical orthogonal functions (EOF) analysis, and gave similar results for all datasets. A similar staircase behavior was found in global NCEP/NCAR reanalyses of 300mb meridional wind and outgoing longwave radiation (OLR) in northern and southern midlatitudes. These many different sources confirm the reality of the regime-shift staircase structure of recent warming, which is masked by short-term ENSO variability and the effects of volcanic eruptions. The warming amplitude of the analysed datasets has not changed significantly after the adjustment, but the shape changed considerably. Adjusted for ENSO temperature dynamics the considered datasets have a striking staircase form: linear trends for three quasi-stable periods 1950-1987, 1988-1997 and 1998-2014 are near zero and nearly all warming occurred during the two shifts of 1987/1988 and 1997/1998 (Fig. 1a, b, c and d). a b с d Fig. 1. Staircase consisting of regimes and shifts in various climate parameters: a) adjusted for ENSO and volcanoes yearly global surface temperature anomalies (HadCRUT4) at 1950-2014 years; b) adjusted for ENSO monthly SST anomalies (ICOADS) at 1950-2016 years and aerosol optical depth (reflecting influence of major volcanic eruptions); c) The same as ‘b' for satellite based SST measurements (NCEP OI v2) at 1983-2016 years; d) The same as 'b' for databases of satellite measurements of lower troposphere temperature (UAH MSU v6.0 and RSS MSU v3.3) at 1980-2016 years.

Аннотация: The residual dynamics left after adjusting global surface temperature anomalies(1950-2014) for short-term variability from El Nino Southern Oscillation (ENSO) and volcanic eruptions have a staircase pattern.Linear trends for three quasi-stable periods 1950-1987, 1988-1997 and 1998-2014 are near zero with nearly all warming occurring during two step-like shifts in the years 1987/1988 and 1997/1998.

Аннотация: Решается задача обеспечения безопасности корпоративной сети научно-исследовательской организации. Обоснована актуальность поддержки превентивных мер защиты сетевых ресурсов для организаций, выпол- няющих научную поддержку высокотехнологичного производства, проведения космических исследований и соз- дания наукоемкого оборудования, где потеря конфиденциальных данных при несанкционированных внешних воздействиях может привести к существенным последствиям. Для решения задачи предложено проводить анализ аномалий сетевого трафика, которые могут свидетельствовать о возникновении киберугроз. Выполнен обзор существующих методов и программных продуктов, предназначенных для анализа сетевых аномалий. На их основе предложен собственный оригинальный программный инструмент, позволяющий авто- матически выполнять обнаружение аномалий и проводить последующий детальный анализ журналов сетевых служб по выбранным администратором метрикам. Программный инструмент разработан в виде веб-приложения, интегрированного в действующую инфраструктуру корпоративной сети научной организации. Внедрение веб- приложения показало актуальность и востребованность развития системы обнаружения аномалий. Для дальнейшего расширения методов защиты корпоративной сети разработано полнофункциональное программное обеспечение - автономная система анализа журналов, которая выполняет автоматический ана- лиз и агрегацию данных сетевых служб и предоставляет интерактивные средства визуализации результатов. Система имеет удобный графический интерфейс, позволяющий наглядно оценивать статистику обнаружен- ных аномалий. При помощи программного инструмента администратор может выявлять наиболее критич- ные инциденты и пресекать их в дальнейшем, изменяя конфигурацию активных систем защиты. Программное обеспечение содержит инструменты для построения диаграмм, отображающих количество аномалий за периоды времени, их распределение по наблюдаемым сервисам, источникам угроз. Оно показывает данные по активным клиентам, подверженным угрозам, частоту запросов по выбранным протоколам, от- слеживает превышение пороговых значений и пр. Применение разработанного программного обеспечения позволяет выполнять конфигурацию первой линии защиты от сетевых атак, повышает оперативность реагирования и эффективность предотвращения втор- жений за счет выявления пропущенных стандартными средствами защиты инцидентов.
The problem of securing the corporate network of a research organization is being solved. The urgency of support- ing preventive measures for protecting network resources for the organizations performing scientific support of high- tech production, conducting space researches and creating high-tech equipment is grounded, where the loss of confi- dential data with unauthorized external influence can lead to significant consequences. To solve the problem, it is sug- gested to analyze the anomalies of network traffic, which can indicate the occurrence of cyberthreats. The paper reviews the existing methods and software products designed to analyze anomalies. On their basis, we propose our own original software tool that allows automatic detection of anomalies and subsequent detailed analysis of network service logs according to the metrics chosen by the administrator. The software tool is designed as a web application integrated into the existing infrastructure of the corporate network of a scientific organization. The implementation of the web application showed topicality and relevance of the development of an anomaly detection system. To further expand the methods of protecting the corporate network, full-featured software has been developed (Autonomous Log Analysis System) that performs automatic analysis and aggregation of network services data and provides interactive means of visualizing results. The system has a convenient graphical interface that allows you to visually evaluate the statistics of detected anomalies. With the help of a software tool, the administrator can identify the most critical incidents and suppress them in the future, changing the configuration of active protection systems. The software contains tools for constructing diagrams that show the number of anomalies over time periods, their distribution by observable services, sources of threats. It shows data on active clients exposed to threats, frequency of requests for selected protocols, monitors the exceeding of thresholds. The application of the developed software allows the configuration of the first line of protection against network attacks, improves responsiveness and the effectiveness of intrusion prevention by detecting missed by standard means of protection of incidents.

    Engineering mode hybridization in regular arrays of plasmonic nanoparticles embedded in 1D photonic crystal
/ V. S. Gerasimov [et al.] // J. Quant. Spectrosc. Radiat. Transf. - 2019. - Vol. 224. - P303-308, DOI 10.1016/j.jqsrt.2018.11.028 . - ISSN 0022-4073
Аннотация: We analytically and numerically study coupling mechanisms between 1D photonic crystal (PhC) and 2D array of plasmonic nanoparticles (NPs) embedded in its defect layer. We introduce general formalism to explain and predict the emergence of PhC-mediated Wood–Rayleigh anomalies, which spectral positions agree well with the results of exact simulations with Finite-Difference Time-Domain (FDTD) method. Electromagnetic coupling between localized surface plasmon resonance (LSPR) and PhC-mediated Wood–Rayleigh anomalies makes it possible to efficiently tailor PhC modes. The understanding of coupling mechanisms in such hybrid system paves a way for optimal design of sensors, light absorbers, modulators and other types of modern photonic devices with controllable optical properties. © 2018 Elsevier Ltd

    Мониторинг температуры земной поверхности территории Красноярска и окрестностей на основе спутниковых данных LANDSAT-8
[Текст] : статья / А. К. Матузко, О. Э. Якубайлик // Успехи современного естествознания. - 2018. - № 7. - С. 177-182 . - ISSN 1681-7494

Аннотация: Настоящая работа посвящена анализу температурных аномалий в городе Красноярске и его окрестностях («городские острова тепла»), которые оценивались по спутниковым данным Landsat-8 теплового инфракрасного диапазона и наземным данным с автоматизированных постов наблюдения за атмосферой. Актуальность исследования обусловлена крайне неблагоприятной экологической обстановкой в городе, сложностью оценки метеорологических характеристик территории из-за значительной неравномерности рельефа, температурным режимом разрезающей город пополам реки Енисей, который обусловлен расположенной в 40 км от города Красноярской ГЭС. Задача состояла в выявлении характерных температурных неоднородностей в городе, их пространственного местоположения и количественной оценке. Всего было рассмотрено 10 безоблачных сцен Landsat-8 на территорию Красноярска и окрестностей, в бесснежный период с 2013 по 2016 гг. Вычисления проводились на основе данных радиометра TIRS (10-й канал – ИК-диапазон 10,3–11,3 мкм). Данные каналов видимого диапазона 4-3-2 (красный-зеленый-синий), регистрируемые радиометром OLI Landsat-8, использовались для классификации изображений, определения типа подстилающей поверхности. Была выполнена обработка спутниковых данных, в том числе – классификация изображения, определение коэффициентов эмиссии для различных участков городской территории, вычисление температуры поверхности. Также был проведен сравнительный анализ полученных данных с измерениями на метеостанциях. Было обнаружено, что температура, измеренная разными способами, имеет сопоставимые значения. По результатам исследования были сформированы сезонные тепловые аномалии городской территории для трех сезонов – лета, весны и осени. Было выделено несколько сезонных тепловых аномальных зон разного типа – природные возвышенности, территории около нескольких крупных торгово-развлекательных центров, промышленные зоны ряда предприятий, участки теплового загрязнения сточными водами.
The subject of the analysis in this paper were temperature anomalies in the city of Krasnoyarsk and its surroundings («Urban Heat Islands»), which were estimated from satellite data Landsat-8 thermal infrared and ground data from automated observation posts for the atmosphere. The relevance of the study is due to the extremely unfavorable environmental situation in the city. The task was to identify characteristic temperature inhomogeneities in the city, their spatial location and quantitative assessment. In total, 10 cloudless Landsat-8 scenes were examined on the territory of Krasnoyarsk and its environs during the snowless period from 2013 to 2016. The calculations were based on the data of the TIRS radiometer (10th channel – IR range of 10.3-11.3 µm). The data of the channels of the visible range 4-3-2 (red-green-blue), registered by the OLI Landsat-8 radiometer, were used to classify the images, to determine the type of underlying surface. Satellite data processing was performed. Also, a comparative analysis of the data obtained with measurements at weather stations was carried out. It was found that the temperature measured in different ways has comparable values. According to the results of the study were formed seasonal thermal anomalies of the urban area. Several seasonal thermal anomalous zones of different types such as natural elevations, territories of about several large shopping and entertainment centers, industrial zones of a number of enterprises, sites of thermal pollution by sewage were singled out.

Аннотация: The problem of temperature anomalies is typical for all major cities in the world. Space thermal images are a powerful source of information for analyzing and determining outlines of temperature anomalies within a single territory. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable ecological situation in Krasnoyarsk: where, in addition to high industrial emissions, atmospheric processes also exert their influence, which lead to the fact that impurities linger and concentrate over the city. The development of advanced space technologies allows the collection of a variety of diverse data more efficiently and at a lower cost than the organization of an appropriate ground network of observation posts and points. One of the most interesting and important indicators about the surface of the Earth is the land surface temperature. Land surface temperature is determined by the balance of incoming and outgoing energy. The main and overwhelming source of energy coming to the surface of the Earth is solar radiation. The 10th and 11th bands of Landsat 8 satellite measure thermal infrared radiation (TIR). The thermal infrared range is particularly useful for determining the temperature difference between the city and surrounding rural areas, and for studying the phenomenon of an urban heat island (UHI).
Проблема температурных аномалий характерна для всех крупных городов мира. Космические тепловые снимки являются весомым источником информации для анализа и определения контуров температурных аномалий в пределах одной территории. Определение природы и границ температурных аномалий поможет понять причины неблагоприятной экологической ситуации в Красноярске: где, помимо высоких промышленных выбросов, оказывают влияние атмосферные процессы, которые приводят к тому, что примеси задерживаются и концентрируются над городом. Развитие передовых космических технологий позволяет осуществлять сбор множества разнообразных данных более эффективно и с меньшими затратами, чем организация соответствующей наземной сети пунктов и постов наблюдения. Одним из наиболее интересных и важных показателей о поверхности Земли служит температура земной поверхности. Температура на поверхности Земли определяется балансом приходящей и уходящей энергии. Основным и подавляющим источником энергии, поступающей к поверхности Земли, является солнечное излучение. Каналы 10-й и 11-й Landsat 8 работают в том же диапазоне, что и канал TIR на более ранних спутниках программы Landsat. Каналы 10-й и 11-й спутника Landsat 8 измеряют тепловое инфракрасное излучение или TIR (thermal infrared). Разрешение для тепловых каналов 100 м.

Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable ecological situation in Krasnoyarsk: where, in addition to high industrial emissions, the atmospheric processes also exert their influence, which may cause the impurities linger and concentrate over the city. This paper presents a technique for monitoring the land surface temperature on the basis of thermal infrared data from the 10th band of Landsat 8 satellite. Ground-based temperature data from an environment protection state regional system for observing the state of the atmosphere in the Earth's surface layer are used. The results show that the temperature in the places of temperature anomalies is 5-8 degrees higher than the average surface temperature of the city. Based on the results of an analysis of summer thermal multi-temporal space images, several thermal zones of different nature are outlined in the territory of the city. © Published under licence by IOP Publishing Ltd.

    Configuration of sources of earth’s magnetic field obtained by solving inverse magnetometry problem

Kochnev // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2018. - Vol. 18: 18th International Multidisciplinary Scientific Geoconference, SGEM 2018 (2 July 2018 through 8 July 2018, ) Conference code: 142901, Is. 6.1. - P553-560, DOI 10.5593/sgem2018/6.1/S28.073 . -
Аннотация: Sources of magnetic field are often approximated by dipoles or current loops, however it this work they are approximated by magnetized prisms instead, which is possible due to equivalency between magnetized objects and currents. Distribution of effective magnetization is then obtained by solving inverse magnetometry problem using the adaptive method of refining the unknown values based on discrepancy between initial values and model values. Z-components of Earth’s magnetic field in IGRF-2005 model in geocentric coordinate system are used as initial values. This allows obtaining the distribution of volumetric currents and magnetic moments for the Earth’s core, which is found to be significantly asymmetric, with four major anomalies, corresponding to surface anomalies: Australian, Canadian, South-Atlantic and Siberian. Work contains additional analysis of the model, initial values and features of the used method in relation to obtained result. Potential source of energy maintaining the currents is suggested, in form of tidal forces, caused by the gravitational influence of the Moon and the Sun. © 2018, International Multidisciplinary Scientific Geoconference.

Аннотация: Satellite data in the thermal infrared range are a powerful source of information for the analysis and determination of city urban area temperature anomalies. The article presents a technique for monitoring the land surface temperature on the basis of combination of "Landsat 8" satellite thermal infrared data with Planet-Scope satellite constellation high resolution data. Such combination of satellite data from several spacecrafts increase the detalization of temperature maps to the level of individual city blocks. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable environmental situation in Krasnoyarsk, where, in addition to high industrial emissions, their influence and atmospheric processes, leading to the fact that impurities are delayed and concentrated over the city. The results shows that the temperature in the places of thermal anomalies is 5-8 higher than the average land surface temperature of the city. Based on the results of the analysis of summer thermal multi-temporal space images, several thermal zones of different nature were outlined on the territory under consideration. This information can be used in planning the development of the city, the design of new urban neighborhoods.

Аннотация: Satellite data on total ozone content for 1985-2015 have been used. Methods of evaluating ozone deficit in the polar region and its excess in middle latitudes of the Southern Hemisphere have been developed. In early spring the ozone molecules outflow and the ozone anomaly forms. Ozone inflows the middle latitudes, its total content increases and a ring with elevated TO forms. In October-November the dynamic process reverses, from the ring the ozone molecules transfer to the polar latitudes. The amount of ozone leaving the ring into the polar regions and filling the ozone anomaly is virtually the same. The results produces indicate that the Antarctic ozone hole is a natural geophysical formation. © The Authors, published by EDP Sciences, 2018.
