Abstract

Worldwide escalation in wildfire incidences calls for continuous monitoring and early detection of fires to strengthen regional fire combating strategies. Inter-annual variability in fire count and Fire Radiative Power (FRP), spatial spread of fires in the most active seasons during 2012‒2023 on Indian landmass are reported. Fire data is extracted from 375 m active fire detection product of Visible Infrared Imaging Radiometer Suite (VIIRS) hosted by Suomi National Polar-orbiting Partnership. In every fire-year (March-February), constructed from the month of remarkable escalation in fires, fires were most populated in March or April in summer and November in winter. The yearly sum of fire spots ranged from 492,282 (2013) to 731,154 (2021). Inter-annual fire count trend grew at a rate of 10,794 per year, excluding COVID years of 2020 and 2021. Many cities with > 0.1 million population are located within or adjacent to the fire hot spots (20 km × 20 km grids), implying possibility of some impacts of seasonal fires both within and outside Wildfire Urban Interphases (WUIs). The study highlights the urgency of streamlining interventions to minimize wildfire incidences in order to protect forests, habitats, biodiversity, ecosystem services, human lives and property and minimize carbon loss, air pollution, perturbations in regional meteorology and radiative forcing.

印度陆地上卫星探测的生物质火灾及其火辐射功率的年代际（2012-2023）时空变化。

世界范围内野火事件的升级要求对火灾进行持续监测和早期发现，以加强区域灭火战略。报告了2012-2023年印度大陆火灾数量和火灾辐射功率（FRP）的年际变化，以及最活跃季节火灾的空间蔓延。火灾数据提取自由芬兰国家极轨伙伴关系主办的可见光红外成像辐射计套件（VIIRS）的375米主动火灾探测产品。在每一个火年（3 - 2月），从火灾显著升级的月份开始，夏季的3月或4月和冬季的11月是火灾最严重的月份。每年的火点总数从492,282（2013年）到731,154（2021年）不等。年际火灾数量以每年10794起的速度增长，不包括2020年和2021年的COVID年。许多拥有10万至10万人口的城市位于火灾热点（20 km × 20 km网格）内或附近，这意味着季节性火灾可能在野火城市界面（WUIs）内外产生一些影响。该研究强调了简化干预措施以尽量减少野火发生率的紧迫性，以保护森林、栖息地、生物多样性、生态系统服务、人类生命和财产，并尽量减少碳损失、空气污染、区域气象扰动和辐射强迫。

期刊介绍： We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
