Heatwave Hazard Assessment – EURO-CORDEX Based Climate Indices (RCP4.5 & RCP8.5) – İzmir Province, CRIZ-ERS

This dataset contains the results of a heatwave hazard assessment for Izmir, Turkey, based on high-resolution regional climate model projections from EURO-CORDEX. The workflow follows the methodology provided in the CLIMAAX Heatwaves workflow and applies user-defined absolute temperature thresholds Heatwaves are calculated using the XCLIM climate index library based on absolute temperature thresholds: Maximum daily temperature ≥ 35°C Minimum daily temperature ≥ 20°C Duration thresholds: 3–5 consecutive days Three hazard indicators are computed: Heatwave Index (HWI) Heatwave Frequency (HWF) Heatwave Total Length (HWTL) Scenarios: Historical (1971–2005) RCP4.5 (2006–2100) RCP8.5 (2006–2100) Outputs: GeoTIFF rasters (EPSG:4326) Annual aggregated values Mean spatial summaries Unit: HWI: number of heatwave events HWF: events per year HWTL: days per year Resolution: ~12 km (EUR-11 domain) Folder Structure : ├── data_izmir│ ├── hwfh.tif│ ├── hwfp45.tif│ ├── hwfp85.tif│ ├── hwih.tif│ ├── hwip45.tif│ ├── hwip85.tif│ ├── hwtlh.tif│ ├── hwtlp45.tif│ └── hwtlp85.tif└── plots_izmir ├── heatwave_fno.png ├── heatwave_freq.png └── heatwave_index.png
