An urban heat island (UHI) refers to a metropolitan area significantly warmer than its rural surroundings. Accurately quantifying UHI intensity (UHII) relies on selecting appropriate areas, which lack universal definition. A crucial aspect in UHII quantification is considering the spatial extent of effect, known as footprints (UHIFP). Here, we propose framework jointly estimate both and UHIFP, integrating latter into former. Our approach involves creating 12 equal-area buffer zones around each boundary initially three farthest areas. Using seamless 1-km daily land surface temperature dataset Google Earth Engine, constructe exponential decay models characterize variations along urban-area gradient city extract UHIFP from these models. The results reveal that average during daytime nighttime are 2.6 2.7 times size, respectively, predominantly located before zones, thereby verifying effectiveness selected areas for accurate calculations. This critical evaluating risks associated with extreme heatwaves stress. It also provides suggestions mitigation measures an urban-rural perspective.

Comprehensive Evidence That Detecting Urban Signals in Large‐Scale Warming Is Highly Uncertain

Geophysical Research Letters, Год журнала: 2025, Номер 52(5)

Опубликована: Март 7, 2025

Abstract Increasing urbanization causes urban heat island effects that might introduce significant biases into global warming estimates. Previous studies of signals and asymmetries remain a subject debate. Here we comprehensively assess urban‐induced warmings by investigating meteorological temperatures on 2,370 stations in China during 1980–2022. There are noticeable annual contributions ranging from 0.016 to 0.251°C decade −1 0.3%–72.4%, primarily due spatiotemporal heterogeneities the criteria defining sites. Rapid tends exacerbate diurnal seasonal asymmetries, resulting shrinking temperature differentials associated with urbanized areas chronosequences. This study underscores specific definition matters for magnitude complex nonlinear imprint asymmetries.
