Heatwave Hazard Assessment - Daily Temperature–Humidity Index (THI) Projections – Gridded and District-Level Ensemble Statistics (Historical, RCP4.5 & RCP8.5) for Aydın Province, Türkiye (CliResDairy)

This dataset contains the heatwave hazard component of the dairy-sector climate risk assessment for Aydın Province, Türkiye, developed under the CLIMAAX project. The dataset provides daily Temperature–Humidity Index (THI) projections derived from EURO-CORDEX regional climate model outputs. THI is calculated using daily near-surface air temperature (tas) and relative humidity (hurs) and represents the intensity of heat stress affecting dairy cattle. The dataset includes both gridded (~0.11°, ~12 km resolution) and district-level aggregated outputs for historical and future climate scenarios.
