Thermal remote sensing with its own concepts and potentials has presented a variety of applications in the atmosphere and land surface temperature (LST) variation detection. The objective of this study is to access the LST variation in the dry season of Binh Duong province for understanding the effect of land-use change on the microclimate conditions. | Vietnam Journal of Science and Technology 55 (4C) (2017) 136-141 ASSESSING THE VARIATION OF THE DRY SEASON’S SURFACE TEMPERATURE IN BINH DUONG PROVINCE FROM 2002 TO 2016 BY APPLYING THERMAL REMOTE SENSING Nguyen Huynh Anh Tuyet1, *, Nguyen Thi Huyen Trang1, Nguyen Thi Khanh Tuyen1, Huynh Thi Kim Yen2 1 Faculty of Natural Sciences, Thu Dau Mot University, 6 Tran Van On, Phu Hoa, Thu Dau Mot, Binh Duong, Viet Nam 2 Educational Testing and Quality Assurance, Hue University of Sciences, 77 Nguyen Hue, Phu Nhuan, Hue, Thua Thien Hue, Viet Nam * Email: anhtuyetqlmt@ Received: 30 June 2017; Accepted for publication: 16 October 2017 ABSTRACT Thermal remote sensing with its own concepts and potentials has presented a variety of applications in the atmosphere and land surface temperature (LST) variation detection. The objective of this study is to access the LST variation in the dry season of Binh Duong province for understanding the effect of land-use change on the microclimate conditions. The spectral radiation value was determined from gray-scale of thermal infrared images of Landsat 7 ETM+ and Landsat 8 OLI/TIRs, followed by the LST calculation. Results showed that the LST in dry season decreased approximately C over the past 15 years from C in the year 2002 to C in the year 2016, due to a large area of newly planted land of industrial trees changed into mature ones in 2016. The area, in which temperature increased corresponding to % of the natural square, has developed rapidly with new industrial parks, urban areas, and vacant land areas. Therefore, the Government should have solutions to promote its positive side and mitigate its negative side by a suitable land-use structure in order to both develop the economic continuously and help to mitigate the climate change effects.
