The objectives of this study are to precisely observe time-series land surface temperature (LST) variations at Mt. Baekdu using total of 23 Landsat TM and ETM+ thermal infrared (TIR) images spanning the 26 years from 1987 to 2012. For this study, we focused on LST of vegetation area, because vegetation area has high surface emissivity. At the same time, we used land surface temperature difference (LSTD) algorithm, which measures the LST difference between reference and target area to minimize the atmospheric effect and the difficulty of surface emissivity determination. The results show that most of the LSTD variations are distributed from -1 °C to 1 °C. However, the north of Mt. Baekdu has some anomaly in June 2004, it represented about 3 °C.
