Climate projections of hazards and weather variables

Our climate projections data are suitable for direct use in climate change impact studies and physical risk assessments. Our referenced high-resolution, multi-model, and multi-scenarios climate projections of weather hazard and variables, is the most coherent collection of climate information available for risk analysis and modeling.

Climate projections features

The climate simulation data have a variety of specifications among which spatial resolution, climate models, future scenarios, temporal resolution and data formats.

High-resolution

A spatial resolution of 0.10°x0.10° (about 10x10 km) over the globe. Temporal resolution is annual for the hazards indicators, daily for the variables, and covers the period from 1981 to 2100.

Multi-scenario

Three Shared Socioeconomic Pathways from IPCC AR6 (SSP1-2.6, SSP2-4.5 and SSP5-8.5) based on the CMIP6 experiment. Other scenarios available on demand. Global Warming levels are also available.

Multi-model

The five reference Earth System Models from IPCC AR6 selected by the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP). More models are added progressively.

Global Warming Levels

Global Warming Levels (GWLs) show how much global temps have risen above pre-industrial conditions (e.g., 1.5°C, 2°C, 3°C, and 4°C). Hazard data can be delivered accordingly.

Custom periods

Hazard annual data can be delivered as is or averaged over 20-years or 30-years periods according to your specifications.

Multiple formats

Data files are netcdf, a commonly used format for climate model data, but depending of the volume of data other formats are possible such as geotifs, shapefiles, and others.

Wildfires

Wildfire hazard indicators based on the Canadian Fire Weather System: Fire Weather Index, Extreme Danger Days and Fire Season Length.

Landslides

Landslide hazard indicators based on NASA’s Landslide Hazard Assessment for Situational Awareness (LHASA) model: Nowcast days for very high, high, and medium risk.

Storms

Storms hazard indicators based on daily maximum surface wind speed: Storm Severity index (SSI) based on scaled exceedance and extreme wind days.

Heat waves

Heat waves hazard indicators based on daily maximum and minimum surface temperature: heat wave duration index and periods, consecutive summer days and periods, very warm days and nights.

Cold and frost waves

Cold and frost waves hazard indicators based on daily maximum and minimum surface temperature: cold wave duration index and duration, consecutive frost days index and periods, very cold days and nights.

Droughts

Meteorological drought hazard indicators based on daily total precipitation: dry days Index, consecutive dry days index, number of consecutive dry days periods.

Heavy precipitation

Heavy precipitation hazard indicators based on daily total precipitation: very heavy precipitation days, very wet days, precipitation fraction due to very wet days, and highest five-days precipitation amount.

Floods

Pluvial flood hazard indicators based on daily total precipitation: maximum consecutive five-days precipitation, extreme precipitation total, frequency of extreme precipitation.

Temperature variability and change

Temperature statistics indicators based on daily mean, maximum and minimum surface temperature: monthly daily mean/max/min temperature and daily temperature range by calendar month.

Precipitation variability and change

Total precipitation statistics indicators based on daily total precipitation: monthly total precipitation by calendar months, rainy days, rainy days, consecutive rainy days, consecutive rainy periods.

Water stress

Evapotranspiration indicators according to several formulas.
