Land Use/Land Cover (LULC) maps deliver essential information on landscape structure and functions, but such are usually considered static, more progress is needed towards dynamic LULC products. The Dynamic Habitat Index (DHI), for example, has revealed high potential in biodiversity studies, its capability to capture the variability of different types under differing environmental conditions, which turn affect biodiversity, underexplored. In this study, we used NDVI products Copernicus Global Service test if DHIs sensitive changing conditions across over a 4-year period (2017–2020) central European Germany.

Understanding the seasonal variations in surface urban heat island (SUHI) different local climate zones (LCZs) is crucial to efforts reduce impacts of warming on residents. However, such an understanding constrained by lack land temperatures (LSTs) at both high spatial and temporal resolutions. This study created time series LSTs fusing Landsat 8 satellite data gap-filled MODIS products further analyses SUHI seasonality a semi-arid city, Xi'an, China. The results showed that open building types were generally lower than those compact types. highest intensity (7.17 °C) was found 'compact mid-rise buildings' (LCZ2), whereas lowest (3.62 'open high-rise (LCZ4) July. peaked about 17–23 days later background LST. annual hysteresis cycles exhibited anti-clockwise concave-up pattern monsoon-influenced hot-summer humid continental (Dwa per Köppen-Geiger scheme). autumn higher spring under same These provide valuable information for developing mitigation strategies seasons.

Nowadays, in the field of urban climate there is a scientific need to compare Land Surface Temperature (LST) with screen-level air temperature (2mTair). This done our study for Iași city, based on MODIS imagery and situ observations. We assess firstly Urban Heat Island (SUHI) under clear-sky conditions, outlining that SUHI well expressed during year, while its geometry tends be more compact regular nighttime. In summer daytime extension reaches peak, being outlined by 35°C isotherm, winter absent day. LST increases clearly when imperviousness ratio (IMD) overpasses 10% threshold, maximum reached IMD higher than 80%. The comparison observations indicates – 2mTair differences are highest spring (+ 5 +7°C), no major observed. For nighttime generally 1 3°C lower 2mTair. also found intense radiative conditions prone increase both intensity, difference between results meant support policies aiming mitigate heat island effects human population.

Remote sensing satellite data have been a crucial tool in understanding urban climates. The variety of sensors with different spatiotemporal characteristics and retrieval methodologies gave rise to multitude approaches when analyzing the surface heat island effect (SUHI). Although there are considerable advantages that arise from these (spatiotemporal resolution, time observation, etc.), it also means is need for ability capturing spatial temporal SUHI patterns. For this, several land temperature products compared cities Madrid Paris, retrieved five sensors: Spinning Enhanced Visible InfraRed Imager onboard Meteosat Second Generation, Advanced Very-High-Resolution Radiometer Metop, Moderate-resolution Imaging Spectroradiometer both Aqua Terra, Thermal Infrared Sensor Landsat 8 9.

Abstract Green infrastructure‐based heat mitigation strategies can help alleviate the overheating burden on urban residents. While cooling effect of parks has been explored in individual satellite‐based studies, a global, multi‐year investigation lacking. This study provides comprehensive global assessment daytime surface park cool island ( SPCI ) climatology, using land temperatures from 2,083 systematically selected worldwide (2013–2022). Through detailed selection and data stratification, key drivers influencing observed intensity are isolated. The analysis reveals that is strongly linked to type, with well‐treed being, average, 3.4°C, cooler than surrounding area during summer. It further investigated how influenced by seasonal variations, droughts, morphology across diverse background climates. These findings, along developed set, offer critical insights for designing climate‐resilient green spaces.
