Abstract:

The dataset contains high resolution simulations of factual and counterfactual maximum (across time of the event) flood depth and derived flooded areas associated with storm surges induced by tropical cyclones. The factual simulations are based on observed relative water levels, i.e. accounting for long-term sea level rise over the historical period. The counterfactual dataset is created by removing the long-term sea level rise from the water level inputs (Treu et al., 2024).

In both cases, the information about TC tracks and wind intensities is derived from the International Best Tracks Archive (IBTrACS) covering the period from 1950 to 2024 To put the historical increase in flooded areas into perspective, we additionally provide data assuming 1m of relative sea level rise along all coastlines. All spatial maps are provided at a 30 arcsec (~1 km) spatial resolution and in netCDF format.

The factual and counterfactual datasets are included into the ISIMIP3a climate-related forcing data Frieler et al., 2024), while the simulations assuming 1m of relative sea level rise are made accessible as secondary input data.
