Extreme Precipitation Hazard Dataset – Intensity–Duration–Frequency (IDF) and Return Period Projections (EURO-CORDEX, 12 km) - İzmir Province - CRIZ-ERS

The hazard component quantifies projected changes in extreme rainfall characteristics derived from EURO-CORDEX regional climate simulations for İzmir, Türkiye under CLIMAAX Project. The workflow: Download EURO-CORDEX precipitation flux (3-hour & daily) Compute annual maximum precipitation (3h and 24h) Fit Generalized Extreme Value (GEV) distribution Derive return levels (2–500 years) Generate IDF curves Calculate shifts in: Return period (frequency) Magnitude (mm) Precipitation change factor Timeframes: Historical: 1976–2005 Future: 2041–2070 Scenarios: RCP4.5 RCP8.5 Hazard Outputs Annual maximum precipitation (mm) IDF netCDF files Return period maps (years) Return period shift maps Folder Structure EXTREME_PRECIPITATION_Hazard_Assessment_izmir.ipynb Reproducible Jupyter Notebook
