The increasing anthropogenic heat, which is emitted from human activities and energy consumption in urban areas migrates to the atmosphere, significantly alters surface balances local climate turn generates heat islands (UHIs). Anthropogenic flux (AHF) has been estimated with balance residual inventory methods. However, these methods have large uncertainty fail further explore spatial distribution of at scales due limited data availability complexities activities, geometry, landscapes building thermal properties. From sources UHIs based on thermodynamics, this study deduces that AHE difference between surrounding rural can be quantified as for natural radiation areas. Thus, an index (UAHI) proposed quantify contribution AHF UHIs, a proxy AHF. UAHI generated using normalized differences urban–rural land temperature (LST) albedo derived both Landsat MODIS data. We investigate temporal association Beijing. results demonstrated average annual UAHIs Beijing ranged 0.168 0.208 steadily improved last decade. represent detailed heterogeneity variations correlation coefficients range 35% 50%. also identify dynamics hotspots heating cooling Overall, convincing indicator providing new option quantifying improving knowledge environments.
