Future heavy precipitation hazard
Overview
A global dataset at 0.1° degrees 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. – Very wet days: Annual number of days with daily precipitation above the 95th percentile of the reference period. – 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. – Highest 5-day precipitation amount: Annual (or monthly) maximum total precipitation accumulated over five consecutive days. |
| 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.
