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)
