Urban thermal comfort & sleep in Seville (May–July 2023): questionnaires and ERA5-Land exposures

his dataset links two primary data sources collected in Seville, Spain (May–July 2023): (1) on-site thermal-comfort questionnaires (n=237) with timestamp and site codes; and (2) an online sleep questionnaire fielded in the same season. For each thermal-comfort interview we computed objective meteorological exposures from ERA5-Land hourly reanalysis at the nearest grid cell and hour: short-wave solar energy on a horizontal plane (from ssrd, Wh m⁻²) and 10 m wind speed (m s⁻¹ from u10,v10). The merged table (237 rows) underpins figures comparing objective exposures to reported sun and wind sensation votes. We share the cleaned questionnaires, the ERA5 exposure table, the merged analysis file, and the plotting/processing scripts. No personally identifying information is included; geographic detail is limited to site codes and fixed site centroids. The dataset is intended for reproducible urban comfort analyses and for methods benchmarking of reanalysis-based exposures in microclimatic settings.
