SPATIOTEMPORAL DISTRIBUTION OF HOTSPOT / WILDFIRE IN SOUTHEAST ASIA USING REMOTE SENSING DATA

摘要

Wildfire including forest fire and slash-and-burn farming are recognized as not only the causes of degradation of biodiversity and land use change, but also the sources of greenhouse gases(GHG) as well as air pollution. In Southeast Asia, more people are recently concerning about the health issue due to the air pollution and particle matters(PM). Wildfire including forest fire is assumes to be an important source of the pollution, and Remote Sensing is expected to be used for providing the information about the wildfire in regional scale on real-time basis. In this research, the spatial and temporal distribution of hotspots was analyzed by using 10 years' data from 2008 to 2017 of MODIS Active Fire Product(MOD14). Several regions from Southeast Asia were set as the study area. The frequency of occurrence of hotspots in each region and the characteristics of the fire radiation power(FRP) of hotspots were analyzed to characterize the hotspots in the regions. Himawari 8 data was also used to evaluate the power of fire detection by using its high temporal resolution, then the feasibility of real-time basis monitoring is discussed.
