Аннотация: Variety of radiation power of wildfire was investigated by processing TERRA/Modis imagery in 4 ?m spectral band. Fire radiative power (FRP) was used for calibrating high-temperature event database obtained by the satellite technique. An analysis was performed on the database of Siberian wildfires for 2010- 2012. Dynamics of FRP was investigated for a number of wildfires including some cases of crown fire. FRP variation was evaluated for various forest zones of Siberia. Classification of wildfires was elaborated in terms of FRP value as a GIS-layer over the territory of Siberia. ©2013 by Forest Research Institute.

лесной пожар -- мощность теплоизлучения -- FRP -- термически активные зоны -- геопространственный анализ
Аннотация: На основе методик обработки съемки в инфракрасном диапазоне (4 мкм) со спутника Terra/MODIS исследованы вариации мощности излучения от пожаров. Использована методика вычисления показателя FRP (Fire Radiative Power), позволяющего оценить интегральную радиационную мощность теплоизлучения от термически активного участка. Обработка была проведена для базы данных пожаров, зафиксированных в Сибири спутниковыми методами в 2012 г. Каждая запись о пожаре в базе данных включает серию детектированных термически активных зон. Для каждой зафиксированной термически активной зоны вычислен показатель FRP. Проведен анализ динамики показателя FRP в течение времени развития пожара. Выявлены пределы вариации FRP для пожаров, развивающихся в различных условиях и в различных типах леса. Проведена классификация пожаров в Сибири на основе величины FRP, результат которой представлен в формате векторного полигонального покрытия для ГИС.

Estimating the influence of external environmental factors on fire radiative power using satellite imagery
[Text] / E. G. Shvetsov, E. I. Ponomarev // Contemp. Probl. Ecol. - 2015. - Vol. 8, Is. 3. - P337-343, DOI 10.1134/S1995425515030142. - Cited References:29. - This research was carried with support from a grant of the Russian Scientific Foundation, project no. 14-24-00112.

Аннотация: In this work the influence of external environmental factors (prevailing forest stands, intensity of the fire season, and weather conditions) on power released by fire (fire radiative power (FRP)) has been studied. The data from the Moderate Resolution Imaging Spectroradiometer (MODIS) are used to characterize variations of the FRP. Our studies show that, during periods of high fire activity, the FRP is 10% higher than during periods of low fire activity. The correlation level between the FRP and weather fire danger is determined. In particular, the fire weather index (FWI) of the Canadian weather fire-danger-assessment system shows a closer relationship with the FRP than the Russian PV-1 index. Based on the results, it is found that fires in forests with a predominance of larch have higher FRP values (by 20-25%) for the forest zone of Siberia than fires in deciduous and pine forests.

Аннотация: As applied to the conditions of wildfires in Siberia, remote sensing is adapted to record the radiation power from the active fire zone in the range of 3.929-3.989 m (Terra/MODIS data). The limits of variation of the detected values of heat radiation are evaluated. Sporadic peaks that exceed the mean value of heat radiation in the fire field by a value of 2.5 sigma were correlated with high-intensity fires, including crown fires. The probability of remote fire detection in crown stage was no less than 65%. The quantitative dependence of the Fire Radiative Power (FRP) on the area of the active zone was determined using a subpixel analysis. The fraction of forest fires in Siberia with areas of extreme heat radiation is shown to be 5.5 +/- 1.2% of the total wildfires. The total area of high-intensity wildfires including crown fires is at least 8.5% of the average annual wildfire area and reaches values of 15-25% during extreme fire seasons.

Calibration of Estimates on Direct Wildfire Emissions from Remote Sensing Data

Аннотация: This study is based on the processing of satellite imagery in the wave range 3.93-3.99 mu m (Terra/Modis satellite) and numerical simulation results. It has been found for combustion conditions in Siberian forests that the observed fire radiative power (FRP) is 15% of the total fire power. Variations between 10 and 30% depend on both the fire development scenario (specific burnup rate of 0.01-0.1 kg/m(2) s and fire front velocity of 0.01-0.1 m/s) and the conditions for remote imaging. Instrumental estimates for the ratio of fire areas by given intensity quantiles for Siberian forests are presented. The share of low-, medium-, and high-intensity fires is 41.2-58.9, 35.0-46.5, and 6.10-13.44% of the total area. Refined estimates of fire emissions have been obtained taking into account the amount of biomass burnt and variable burning intensity. The proposed method allows the mass of burned forest fuel materials (FFM) and direct fire emissions to be estimated quantitatively at a level 14-21% lower than the values calculated with the help of standard approaches. The estimates of direct carbon emissions in the given time interval of 2002-2016 were 83 +/- 21 Tg/year on average, which is 17% lower than the value 112 +/- 25 Tg/year obtained with the standard method.

Satellite monitoring of the wildfire in Siberia and fire emissions estimation

Аннотация: Using the threshold-based method for classifying thermally active pixels on Terra and Aqua / MODIS images we identified categories of combustion intensity for different parts of fires considering main types of forest stands in Siberia. The threshold values and the corresponding fire categories were determined based on the statistical values of the Fire Radiative Power (FRP) of the fire pixels. Using the long-term fire database (2002–2019, Sukachev Institute of Forest SB RAS, Federal Research Center KSC SB RAS), we obtained instrumental estimates of direct fire carbon emissions for the territory of Siberia. Direct emissions from fires varied from minima values of 20–40 Tg/year (2004, 2005, 2007, 2009, 2010) to maxima values of 200 Tg/year during the 2012 and 2019 extreme fire seasons. Preliminary estimation on carbon emission for 2020 is 180 Tg C/year. Fires in the larch forests of the flat-mountainous taiga region (Central Siberia) made the greatest contribution (more than 65 %) to the total emissions. Estimates of the probable level of emissions are provided considering various IPCC climatic scenarios. Considering RCP2.6, RCP4.0 and RCP8.5 climatic scenarios it is possible that the direct fire emissions will increase more than twice until the end of the XXI century. At the same time extreme climatic scenarios (RCP8.5) can result in a tenfold increase in emissions. © 2020 Space Research Institute of the Russian Academy of Sciences. All rights reserved.
