Future heavy precipitation hazard dataset

A global dataset at 0.1° resolution of four heavy precipitation indicators from five climate models under three Shared Socioeconomic Pathways (SSPs) scenarios from the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). The time resolution is annual from 1981 to 2100.

Heavy precipitation dataset specifications

Specification	Description
Experiment	CMIP6
Scenarios	Shared Socioeconomic Pathways SSP5-8.5, SSP2-4.5 and SSP1-2.6.
Climate models	The 5 models selected by the ISIMIP initiative: IPSL-CM6A-LR, GFDL-ESM4, UKESM1-0-LL, MPI-ESM1-2-HR, MRI-ESM2-0.
Spatial resolution	0.1° x 0.1° Global
Temporal resolution	Annual from 1981 to 2100
Indicators	The heavy precipitation hazard indicators are based on total precipitation calculated using the following definitions: Very heavy precipitation days index: Annual count of days with daily precipitation equal to or above 20 mm. The unit is days. Very wet days: Annual number of days with daily precipitation above the 95th percentile of the reference period. The unit is days. Precipitation fraction due to very wet days: Annual (or monthly) total precipitation amount falling during very wet days, expressed as a fraction of total precipitation. The unit is a numeric rating. Highest 5-day precipitation amount: Annual (or monthly) maximum total precipitation accumulated over five consecutive days. The unit is mm.
Format	NetCDF, other formats possible depending on data volume.

Supplementary information

The Future Heavy Precipitation dataset provides climate indicators that quantify the frequency and intensity of extreme rainfall events under historical and future climate scenarios. Derived from daily precipitation data, each metric is calculated using scientifically defined absolute and percentile-based thresholds, and is based on downscaled simulations from CMIP6 global climate models, enabling analysis across multiple spatial and temporal scales.
