Future Precipitation Variability hazard dataset

A global dataset at 0.1° resolution of five 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.

Precipitation variability 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 precipitation variability indicators are calculated using the following definitions: Annual total precipitation: Total amount of precipitation accumulated over the year, based on daily values. The unit is mm. Rainy days index: Annual number of days with daily precipitation equal to or above 1 mm. The unit is days. Consecutive rainy days index: Maximum number of consecutive days in a year with daily precipitation equal to or above 1 mm. The unit is days. Number of consecutive rainy days periods: Annual count of periods with at least 2 consecutive days with daily precipitation equal to or above 1 mm. The unit is periods. Precipitation intensity: Annual average precipitation amount per rainy day (i.e., total annual precipitation divided by the number of wet days). The unit is mm/day.
Format	NetCDF, other formats possible depending on data volume

Supplementary information

The Precipitation Variability dataset provides climate indicators that describe the distribution, persistence, and intensity of rainfall under historical and future climate scenarios. Derived from daily precipitation data, each metric is computed using absolute thresholds (e.g., ≥1 mm/day) and is based on downscaled simulations from CMIP6 global climate models, supporting multi-scale climate impact analysis.
