Spatial and Temporal Distribution of Forest Fire PM10 Emission Estimation by Using Remote Sensing Information

Abstract

This study aims to assess the PM10 emission emitted and the spatial and temporal distribution of PM10 emissions from forest fire during the 2005-2009 periods. The active fire product is known as fire hot spots (FHS) from MODerate-resolution Imaging Spectro-radiometer (MODIS) sensor were used to assess the forest fire areas in Thailand. During this period, Active fires was detected nearly 87,000 FHS with a highest significant in the deciduous forest, corresponding with a damaged forest area of about 78,200 km2 and about 92% of it was burned habitually. The effecting of forest fire had resulted in a combusted surface fuel of approximately 22,388,000 tonns dry matter and PM10 emission was emitted at 187,331 tonns. The obtained results have been used occasionally as reference to develop risk area map of PM10. Risk area map is often use as a reference for many decision-making policies.
