title: Heatwave Hazard Assessment for İzmir (Türkiye): CMIP6 Ensemble-Based Heatwave Detection under SSP245 and SSP585 -  (CRIZ-ERS)

description: This dataset contains the heatwave hazard assessment for İzmir Metropolitan Area developed under the CLIMAAX project.

Heatwave events were detected using daily minimum and maximum temperature projections from the NASA NEX-GDDP-CMIP6 dataset. Multi-model ensemble median data were used for SSP245 and SSP585 scenarios.

Heatwaves are defined as ≥5 consecutive days during June–August where both Tmin and Tmax exceed the 90th percentile of the 1980–2010 baseline period.

The dataset includes ensemble climate data, detected heatwave statistics, and visual outputs.

title: Extreme Precipitation Hazard Assessment for İzmir (Türkiye): EURO-CORDEX Ensemble-Based IDF Analysis under RCP4.5 and RCP8.5 - CRIZ-ERS

description: This dataset contains the extreme precipitation hazard assessment for İzmir Metropolitan Area developed within the CLIMAAX project.

The analysis is based on EURO-CORDEX regional climate model simulations (0.11° resolution). Annual maximum precipitation was derived from daily precipitation data for the baseline period (1976–2005) and mid-century projections (2041–2070) and (2071-2100) under RCP4.5 and RCP8.5 scenarios.

A Generalised Extreme Value (GEV) distribution was fitted pixel-by-pixel to derive Intensity–Duration–Frequency (IDF) curves for 24-hour duration events. Multi-model ensemble statistics (median, 10th and 90th percentiles) were computed to represent model uncertainty.

The dataset includes IDF return levels and relative climate change signals (%).

title: Extreme Precipitation Risk Assessment for İzmir: Magnitude–Frequency Shift of Design Rainfall Events - CRIZ-ERS

description: This dataset contains the extreme precipitation risk assessment for İzmir Metropolitan Area developed within the CLIMAAX project.

The risk assessment quantifies how climate change alters the frequency and magnitude of a critical design rainfall event (100 mm in 24 hours).

Using ensemble IDF datasets derived in the hazard workflow, a magnitude–frequency shift analysis was applied pixel-by-pixel to compute:





Future return period of the design threshold




Future precipitation magnitude at the same return period




Precipitation scaling factor (future / historical)




Spatial difference in return period



The dataset also includes overlays with critical infrastructure (hospitals, schools, universities).
