UTHECA_USE: A Multi-Source Dataset on Human Thermal Perception and Urban Environmental Factors in Seville

This paper introduces UTHECA_USE, a dataset of 989 observations collected in Seville, Spain (2023–2025), integrating microclimatic, personal, and urban morphological data. It comprises 55 variables, including in situ measurements of air and globe temperatures, humidity, wind speed, derived indices such as the Universal Thermal Climate Index (UTCI), demographic and physiological participant data, subjective thermal perception, and detailed urban form characteristics. The surface temperature data of urban materials are included in a subset. The dataset is openly accessible under a permissive license, and this data descriptor documents the collection methods, calibration, survey design, and data processing to ensure reproducibility and transparency. The UTHECA project aims to develop a more accurate and adaptive outdoor thermal comfort (OTC) assessment model to guide effective, inclusive urban strategies to improve human thermal perception and climate resilience. UTHECA_USE facilitates research on outdoor thermal comfort and urban microclimates, supporting diverse analyses linking human perception, environmental conditions, and urban morphology.
