Urban Heat Risk Assessment for İzmir (Türkiye): Land Surface Temperature and Vulnerable Population-Based Risk Mapping (2022–2025) - CRIZ-ERS

This dataset contains the urban heat risk assessment for İzmir Metropolitan Area developed under the CLIMAAX project. Heat risk is calculated by combining: Hazard: Classified Land Surface Temperature (LST) derived from Landsat 8 (2022–2025) Exposure: Rasterised vulnerable population (age-disaggregated groups) The resulting heat risk index ranges from 2 (very low) to 20 (very high). All spatial layers are provided at 30 m resolution.
