This dataset, published by Grand Paris Sud, provides a municipal-level breakdown of urban heat island (ICU) analysis for its territory. It classifies urban morpho-climatic units (IMU) according to Local Climate Zone (LCZ) typology, distinguishing between day and night readings. It further maps heat-related hazard, notably the aggravation of heat-wave hazard caused by the urban heat island effect, and vulnerability indicators such as the sensitivity of residents and living environments to heat exposure. The data is broken down by commune (municipality) and dated November 2023, supporting local climate resilience and urban planning analysis within the Grand Paris Sud area.Normal 0 21 false false false FR X-NONE X-NONE MicrosoftInternetExplorer4 Les facettes de lecture (à voir en périodes de jour et de nuit). « ALEA », aggravation de l’aléa « Vague de chaleur » par l’effet d’ICU Hauteur de la Vulnérabilité « SENSIBILITÉ », fragilité des personnes et du lieu de vie...
