Analysis of Building Height Impact on Land Surface Temperature by Digital Building Height Model Obtained from AW3D30 and SRTM

Land surface temperature (LST) is heavily influenced by urban morphology. Building height an important parameter of morphology that affects LST. Existing studies show contradicting results where building can have a positive or negative relationship with More are necessary to examine the impact height. However, high accuracy data difficult obtain on global scale and not available in many places world. Using Digital Height Model (DBHM) calculated subtracting SRTM from AW3D30, this study analyzes between Landsat LST two cities: Tokyo Jakarta. The observed during both cities’ warm seasons (April October) Tokyo’s cool (November February). negatively correlated. In morning, areas high-rise buildings tend lower than low-rise buildings. This phenomenon revealed be stronger season. difference mixed-height more significant areas.
