英文摘要	Understanding the warming effect of the impervious surface area (ISA) quantitively is crucial to alleviate the urban heat island effect. However, the quantitative analyses of urbanization-induced land surface temperature (LST) change globally remain to be determined during the global warming hiatus. Here, we first characterized the response of LST to ISA (i.e., delta LST) in 369 global cities using MODIS LST product (1 km) and the global artificial impervious area dataset (30 m). We then investigated the spatiotemporal changes of delta LST and its associated driving factors, including enhanced vegetation index (1 km), albedo (ALB, 500 m), population (100 m), air temperature (AT, 0.1 degrees), and precipitation (0.1 degrees). The analysis was conducted using linear regression models from 2000 to 2010 at the pixel level. The results illustrate that (1) the daytime delta LST in urban areas shows a negative trend with -0.2971 degrees C/% and -0.0870 degrees C/% in arid and temperate regions, and the nighttime delta LSTs were 0.0938 degrees C/% and 0.0048 degrees C/%, respectively. In tropical regions, the delta LST remains positive throughout the day, while it exhibits an opposite trend in snow regions. (2) The magnitude of nighttime delta LST is stronger compared to daytime globally, which is more significant in arid regions with the largest Delta delta LST values (i.e., diurnal variations) in urban (0.3909 degrees C/%) and rural (0.3262 degrees C/%) areas. (3) In temperate regions, the response of ALB to ISA (delta ALB, negative effect) and the response of AT to ISA (delta AT, positive effect) are dominant factors in regulating delta LST during daytime and nighttime, respectively However, in arid regions, the daytime and nighttime delta LSTs are negatively correlated by urban population and vegetation, respectively. These findings provide a quantitative understanding on long-term LST variations and driving factors behind at the pixel level, suggesting that urban greening and increasing surface albedo are effective strategies to mitigate the urbanization-induced surface warming.
