Аннотация: Разработанный алгоритм распознавания и картирования пожарищ по многоканальным изображениям спутников TERRA, завышает оценку площади гари на 2%, в равнении с результатами картирования, по данным спутника LANDSAT+ETM. В то же время, алгоритм картирования пожаров по данным спутника AVHRR/NOAA, позволяет идентифицировать более 70% обнаруженных очагов горения общей площадью пожарищ, превышающую реальные значения почти на 30%. Из анализа причин возникновения неопределенностей и ошибок в оценке дымовых эмиссий, следует, что методика расчета позволяет производить оценку массы дымовых газов с точностью до 30%.

Аннотация: Приводятся результаты прогнозирования возникновения и развития крупных лесных пожаров на территории Сибири. Для оценки пожарных рисков использованы канадская система погодной пожарной опасности лесов (CFFWIS) и российские показатели влажности (ПВ1, ПВ2), входными метеопеременными которых послужили данные из сети метеостанций. Параметры пожаров детектированы по информации со спутников NOAA за 13 лет (1996-2008 гг.). Для определения продолжительности противоопасного сезона дополнительно использованы данные о наличии снежного покрова, полученные по измерениям Terra/MODIS. Учитываются особенности возникновения пожаров на территориях с разными типами горючих материалов. Статистический анализ площадей и количества пожаров, характерных для каждого класса растительности, рассчитан с использованием карты растительности GLC2000.

Аннотация: The prediction results of large-scale forest fire development are given for Siberia. To evaluate the fire risks, the Canadian Forest Fire Weather Index System (CFFWIS) and the Russian moisture indices (MI1 and MI2) were compared on the basis of the data of a network of meteorological stations as input weather parameters. Parameters of active fires were detected daily from the NOAA satellite data for the period of 1996-2008. To determine the length of the fire danger season, the snow cover fractions from Terra/MODIS data (2001-2008) were used. The features of fire development on territories with different types of flammable fuel are considered. The statistical analysis of the areas and number of fires typical of each vegetation class is made with the use of the GLC2000 vegetation map. A positive correlation (similar to 0.45, p < 0.05) between the cumulative area of local fires and the MI1 and Canadian BUI and DMC indices is revealed. The Canadian ISI and FWI indices describe best the diurnal dynamics of fire areas. The above correlations are higher (similar to 0.62, p < 0.05) when we select the fires larger than 2000-10000 ha in size for the forested areas. Other cases point to the lack of a linear relation between the fire area and the values of all indices, because the fire spread depends on many natural and anthropogenic factors.

Аннотация: Fires are a common occurrence in the Siberian boreal forest. The thermal anomalies product of the Terra/Moderate Resolution Imaging Spectroradiometer (MODIS) product suite is designed to detect thermal anomalies (i.e., hotspots or fires) on the Earth's surface. Many, but not all, of the hot spots detected by MODIS in Siberia are wild fires. Agricultural burning and industrial activities also contribute. Using MODIS data from the years 2001, 2002, and 2003 along with a geographical information system (GIS), the type, extent, and duration of hot spots were examined. In addition, high correlations were found between the number of fires and proximity to human activities. Different types of land-cover thermal anomalies were found to have a strong, positive correlation with some anthropogenic features, such as roads, human settlements, and mineral industry locations. The agricultural (r(2) = 0.95) and the forest (r(2) = 0.81) thermal anomalies had the highest positive correlation with proximity to roads. The correlation was stronger between burned forests and roads (r(2001)(2) = 0.81, r(2002)(2) = 0.90, r(2003)(2) = 0.88) than between any forested land and roads (r(2) = 0.52). The results indicate that forest fires tend to occur near agricultural fires (r(2001)(2) 0.93, r(2002)(2) = 0.87, r(2003)(2) = 0.94). Anthropogenic feature and land-cover thermal anomaly (LCTA) relationships tend to be stronger in a high fire year (2003) than in a low fire year (2001). This alone does imply causation, but might be an indicator of natural and anthropogenic factors acting together to shape where and when fires are burning. These findings have important implications for carbon and climate modelers wishing to use MODIS products to quantify and predict carbon storage and climate change.

Аннотация: In this paper NOAA AVHRR data acquired at the Sukachev Institute of Forest in Siberia, Russia is evaluated for forest management mapping applications. First a classification of the entire 1000 km x 3000 km transect was performed, but was found to be too general to be of value. More useful interpretation procedures require a landscape-ecological approach. This means that computer classification should be made separately for segments of territory based ecologically distinct regions. This segmentation of the transect into ecological regions was found to improve the level of detail available in the classification. Using this approach AVHRR data were found to be adequate for small scale mapping at the level of vegetation types or plant formations. A limited study using AVHRR data for classification of mountainous regions showed that AVHRR-derived maps were more detailed than existing landscape maps. AVHRR derived classifications also compared favourably to larger scale forest management maps of softwood and hardwood forests. Current forest management in Siberia relies on very small-scale inventory maps. Thus, there is a potential role for AVHRR (or Terra) data for northern Siberian forest monitoring. The southern forests of the Yenisey meridian (below the 57th parallel) are less uniform due to considerable human activity, and NOAA/AVHRR data will play a subordinate role in its monitoring.

Аннотация: Исследована пространственно-временная динамика экотона горной лесотундры плато Путорана за последние 36 лет на основе космических съемок Landsat (1973, 2009 гг.), Hexagon (1976 г.), Quickbird (2005 г.) и Terra MODIS (2002–2009 гг.). Выделены три основные категории наземного покрова: редколесья с сомкнутостью >0.2; редины с сомкнутостью <0.2 и кустарники; фоновые территории. Площадь редколесий увеличилась на 60%. Этому способствовало увеличение сомкнутости в рединах. Наблюдаемое явление в основном отмечено вдоль долины реки. В зонах роста сомкнутости наблюдается увеличение вегетационного индекса NDVI на 0.14. Рост среднегодовой температуры в течение трех декад конца 20 в. способствовал продвижению древесной растительности по высоте не более чем на 15 м над уровнем моря, и появлению трех новых деревьев на гектар. С ростом высоты над уровнем моря деревья предпочитают локальные депрессии на юго-восточных склонах с крутизной до 30°.

Аннотация: The latest catastrophic Siberian silkmoth (Dendrolimus superans sibiricus Tschetw.) outbreak occurred in central Siberia during 1994-1996. The relationship between forest stand mortality from insects and topographic features (azimuth, elevation, slope steepness) was analyzed based on a high-resolution digital elevation model, a pest damage map and Terra/MODIS data. It was found that pest-induced forest mortality patterns depend on topographic features. Before the outbreak the major part of host forest species was found within the elevation zone of 150-500 m. After the outbreak, surviving dark-needle stands were found mainly at elevations higher than 400 m. The greatest damage was observed at elevations between 210 and 320 m, whereas maximum mortality was observed at elevations of about 200 m and minimal mortality at elevations of 300 m. With respect to slope steepness, maximum damage for all categories was observed for slopes of 5-20В°. Slightly damaged stands were most common at low slope angle (about 5В° or less), whereas the highest proportion of stands with high tree mortality was found on steeper slopes. With respect to azimuth, insect damage is mostly uniform, with a small increase in damage on the south-west-facing slopes. The spatial pattern of the silkmoth outbreak can provide a basis for prioritizing Siberian silkmoth outbreak monitoring. В© 2007 Taylor & Francis.

Аннотация: This paper presents an overview of current satellite-based fire mapping activities at several institutions in Russia that provide operational fire monitoring at federal and regional levels. The current operational systems are based on data from the Advanced Very High Resolution Radiometer (AVHRR) and the TIROS Operational Vertical Sounder (TOVS) on the National Atmospheric and Oceanic Administration (NOAA) operational polar orbiting environmental satellite series. Detailed descriptions of the data acquisition and preprocessing systems, algorithms, and the suite of fire products are provided. Each institution has expertise in addressing a specific aspect of satellite-based fire mapping and monitoring. The methodologies described include proper georegistration of AVHRR data and elimination of false alarms while retaining a high active fire detection rate. Statistical and physical approaches are presented to account for, among other effects, reflection from bright surfaces and clouds, sun-glint, and atmospheric attenuation by smoke and haze. An approach for fire danger estimation is also presented. The fire mapping activities at the various institutions are being organized into a regional network within the international Global Observation of Forest and Landcover Dynamics (GOFC/GOLD) program. Concerted efforts will facilitate the implementation of processing systems for new and improved sensors, such as the Moderate Resolution Imaging Spectroradiometer (MODIS) on the experimental NASA Earth Observing System Terra and Aqua satellites and the Visible/Infrared/ Imager/Radiometer Suite on the next generation National Polar Orbiting Environmental Satellite System (NPOESS).

Аннотация: The Siberian boreal forest is considered a carbon sink but may become an important source of carbon dioxide if climatic warming predictions are correct. The forest is continually changing through various disturbance mechanisms such as insects, logging, mineral exploitation, and especially fires. Patterns of disturbance and forest recovery processes are important factors regulating carbon flux in this area. NASA's Terra MODIS provides useful information for assessing location of fires and post fire changes in forests. MODIS fire (MOD14), and NDVI (MOD13) products were used to examine fire occurrence and post fire variability in vegetation cover as indicated by NDVI. Results were interpreted for various post fire outcomes, such as decreased NDVI after fire, no change in NDVI after fire and positive NDVI change after fire. The fire frequency data were also evaluated in terms of proximity to population centers, and transportation networks.

Аннотация: Wildfire number and burned area temporal dynamics within all of Siberia and along a south-north transect in central Siberia (45°-73° N) were studied based on NOAA/AVHRR (National Oceanic and Atmospheric Administration/ Advanced Very High Resolution Radiometer) and Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) data and field measurements for the period 1996-2015. In addition, fire return interval (FRI) along the south-north transect was analyzed. Both the number of forest fires and the size of the burned area increased during recent decades (p < 0.05). Significant correlations were found between forest fires, burned areas and air temperature (r = 0.5) and drought index (The Standardized Precipitation Evapotranspiration Index, SPEI) (r = -0.43). Within larch stands along the transect, wildfire frequency was strongly correlated with incoming solar radiation (r = 0.91). Fire danger period length decreased linearly from south to north along the transect. Fire return interval increased from 80 years at 62° N to 200 years at the Arctic Circle (66°33' N), and to about 300 years near the northern limit of closed forest stands (about 71°+ N). That increase was negatively correlated with incoming solar radiation (r = -0.95). © 2016 by the authors.

УДК	630.181.22;630.181.65

Аннотация: В настоящей работе предложен новый подход к анализу сезонной фенодинамики древесных растений. Рассмотрена модель фенодинамики, основанная на представлении о фенологических процессах у деревьев в бореальной зоне как о процессах генерации энергии в течение вегетационного сезона и расходования части накопленной энергии на выживание древесных растений в период покоя. Предложено уравнение энергетического баланса, связывающее погодные и фенологические показатели и позволяющее связать фенологические и метеорологические показатели в течение всего года. Модель идентифицирована по данным наземных фенологических наблюдений за березой, осиной, лиственницей сибирской на территории заповедника “Столбы” (55°38? - 55°58? с.ш., 92°38? - 93°05? в.д.) с 1951 по 2012?г. и позволяет с хорошей точностью описать наблюдаемые фенособытия. Коэффициенты модельного уравнения можно рассматривать как показатели восприимчивости древесных растений к воздействию климата. Показано, что для расчетов по модели энергетического баланса можно использовать результаты дистанционных спутниковых измерений. Для определения фенодат в насаждениях листопадных древесных пород использовались ежедневные данные о величине NDVI (Normalized Difference Vegetation Index) изучаемых объектов, представленные спутником Modis/Terra.
Here we show the new approach to analysis of seasonal phenological dynamics of wooded plants. Our model was premised on representation of phenological processes of trees in boreal domain by a process of energy production during the vegetation season and partial release of accumulated energy for survival during resting. We introduced the energy balance equation combining weather and phenological indicators and linking them throughout a year. The model was parameterized using data of phenological studies of birch, aspen, and Siberian larch in Stolby Nature Sanctuary (55°38' - 55°58' N, 92°38' - 93°05' E) during 1951-2012 which allow high accuracy simulation of phenological stages. Coefficients of the equation may be considered as indicators of sensitivity of wooded plants to climate. We show that remotely sensed data on phenological dates may be used in calculations using the model of energy balance. Daily MODIS/Terra images of NDVI (Normalized Difference Vegetation Index) of the studied deciduous forests were used.

Аннотация: Wildfire frequency, relative area burned, and fire return intervals (FRI) have been studied in larchdominated forests along the transect from the southern (45A degrees N) to the northern (73A degrees N) distribution limits of larch stands based on analysis of satellite imagery (NOAA/AVHRR, Terra/MODIS; 1996-2015) and collection of tree cross cuts with fire scars. A significant increasing trend in fire extent (R (2) = 0.50, p < 0.05) has been revealed. Histograms of fire extent and frequency are bimodal in the southern and middle taiga (with peaks in spring-summer and late summer-autumn periods) but become unimodal toward the north (> 55A degrees N). The length of FRI increases from 80 years at 62A degrees N to similar to 200 years at the Arctic Circle and reaches similar to 300 years near the northern limit of larch stands, showing a significant inverse correlation with the length of fire season (r =-0.69). In turn, the length of fire season, area burned and FRI are closely correlated with latitudinal variation in solar irradiance (r = 0.97, 0.81, and -0.95, respectively).

Аннотация: The paper discusses the dynamics of reflectance and thermal anomalies in post-pyrogenic plots under cryolithozone conditions, studied using Terra/MODIS imagery. Long-term consequences of the “background” in the thermal range (10.780–11.280 ?m) are considered, that effect the temperature and water regimes of soils. Rising of the average temperature has been instrumentally recorded for the post-fire plots in the larch forests of Siberia’s cryolithozone in relation to background values by up to ?T = 7.2±1.3 °C during the summer, which is 20–40 % higher than the temperature of the undisturbed plots. Temperature anomalies remain more than 10 years under the conditions of natural restoration of the ground cover. It has been shown that excessive surface heating can lead to an increase in the depth of thawing soil layer by 20 % deeper relative to the average statistical rate. The hypothesis has also been tested of a correlation between the relative forest burning index within the boreal river basins and long-term series of the river discharge. In some seasons, a response to pyrogenic effects is recorded, expressed as an abnormally low discharge during summer period (r ~ –0.57…–0.83, p < 0.05). © 2018 Space Research Institute of the Russian Academy of Sciences.

Аннотация: A method for estimating direct wildfire emissions that considers fire intensity based on infrared radiation data from the Terra/MODIS satellite is proposed. In Siberia, we experimentally established that low intensity fires cover 47 +/- 13% of the total area; that with moderate intensity, 42 +/- 10%; and that with high-intensity, 10 +/- 6%. The average value of wildfire emissions in Siberia is estimated at 83 +/- 21 ?g C/yr (2002-2016), which is considerably lower than the values determined by standard procedure (112 +/- 25 ?g C/yr). Based on the trend of long-term dynamics of fire emissions in Siberia, a probable level of emissions in 2100 is calculated when implementing climate scenarios RCP2.6, RCP4.0, and RCP8.5 (220, 700, and 2300 ?g C/yr, respectively).
