WebbSo we develop a new algorithm, the simplified urban-extent algorithm (SUE), that can be used to automatically calculate the UHI intensity at a global scale. The algorithm is implemented on Google Earth Engine, a cloud-based platform for planetary-scale data archiving and geospatial analysis (Gorelick et al., 2024). Webb5 dec. 2011 · Urban heat island is among the most evident aspects of human impacts on the earth system. Here we assess the diurnal and seasonal variation of surface urban …

For the first deficiency, we forgo the use of buffers and calculate the UHI as the LST difference between the urban and rural pixels, as defined by their spectral characteristics, within each urban …
Webb26 maj 2024 · We found that city-scale UHI was overestimated by 1.19 ± 0.02°C (mean ± SE, n = 342) if LST was used instead of T air (mean SUHI 1.45°C versus mean CUHI 0.26°C; Figs. 1 and 2A).For the cities considered during July 2024, this reflects a sixfold overestimation in the urban contribution to local temperature if satellite observations are … Webb8 feb. 2024 · The “urban extents” derived from NTL imagery in this study were defined as core urban domains, where most built-up areas and partially green spaces and other land-use types with urban functions are inside. The global urban mapping framework was designed based on top-down segmentation and local delineating and bottom-up merging.
