Global Wildfire Output Evaluation Study Published in Top-Tier International Journal in Related Field / Professor Kang Yoo Jin (Department of Forestry, Environment, and Systems)

Professor Kang Yoo Jin of the Department of Forestry, Environment, and Systems, College of Science and Technology, Kookmin University (President Jeong Seung Ryul), has conducted research (supported by the National Research Foundation of Korea) evaluating the fire radiative power (FRP) of three widely used remote sensing-based wildfire products—MODIS, VIIRS, and SLSTR satellite sensors—across global regions. Professor Kang served as the first author of this study, with Researcher Lee Jae Se from Gwangju Institute of Science and Technology (GIST) and Professor Lim Jeong Ho from Ulsan National Institute of Science and Technology (UNIST) participating as co-author and corresponding author respectively.
The findings were published in the internationally renowned journal 『Remote Sensing of Environment』 (top 3.8% in Remote Sensing and top 4.4% in Environmental Sciences according to JCR).
The results indicate that in Africa, the relatively low agreement observed was due to significant fluctuations in the daily fire cycle. Conversely, while subtle differences existed in the fire radiative power (FRP) values measured by the three different satellites, they demonstrated high consistency, particularly in the Boreal Forest region where large-scale, intense wildfires—which significantly impact recent global carbon emissions—occur. Here, all three satellites measured nearly identical intensity levels (see figure below). This confirms that the reliability of satellite-based wildfire information, a core dataset for global climate change research, is exceptionally high in the most critical regions.
Professor Kang Yoo Jin of Kookmin University stated, ‘This study represents the first application of Extended triple collocation to quantify the global consistency of satellite-based fire radiant power (FRP).’ She added, ‘This will significantly contribute to enhancing the reliability of satellite data utilised in global carbon emissions modelling and climate change impact research.’
Professor Lim Jeong Ho of UNIST emphasised, ‘This study represents the first global-scale assessment of the consistency and uncertainty of satellite-derived fire radiative forcing (FRP).’ He stressed, ‘Its significance lies in presenting a novel analytical framework capable of evaluating the consistency of three fire-derived products without requiring reference data.’
