Urban heat island monitoring and analysis based on remotely sensed data

Urban heat island (UHI) is one of the main factors influencing the weather, climate, and environment in urban and its surrounding areas. In this study, MODIS´s MOD11A2 product over the year of 2000-2012 is used to investigate and monitoring the UHI of Dongguan, China. The result indicates that the higher UHI intensity at day-time is frequently occurred in the summer and fall, while the lower UHI intensity is often observed in spring, while no seasonal variation pattern could detect for night-time UHI. During the 13years, the region with higher LSTs is frequently distributed in areas covered by built, roads and bare soils etc., while regions with lower LSTs are mainly occurred in places dominated by waters, forests and parks etc.
