Urbanization entails loss of vegetation coverage and transformation of these lands into urban areas which results in substantial change on urban thermal environment. Urban heat island (UHI) is considered as of the main reasons behind urban micro climate warming. In this study, we focus on the effect of changing land cover on night time thermal environment also known as ‘Tropical night’ and land surface temperature for Seoul capital area from 1996 to 2016 based on satellite images. Results of the assessment showed that, fallow land and vegetation regions decreased, while urban areas expanded dramatically over 20 years. Land surface temperature was found to rise in 0.14℃/10years over the study area due to urbanization whereas tropical nights (TNs) were found approximately 1.5 times higher in 2006-2016 than the past 1996-2006 over study area. The study also demonstrated the significance of green space and appropriate roof materials for mitigating urban thermal effect.
