CHC-CMIP6 a été explicitement développé pour permettre l'analyse des risques liés au climat au cours du passé récent et dans un avenir proche.
Cet ensemble de données de projections climatiques contient des données mondiales quotidiennes sous forme de grille pour les périodes d'observation (1983-2016) et de projection (2030 et 2050). Il doit être utilisé pour identifier et surveiller les extrêmes hydroclimatiques. L'ensemble de données contient des grilles mondiales quotidiennes haute résolution (0, 05°) du produit de température Climate Hazards InfraRed Temperature with Stations (CHIRTS-daily), du produit de précipitations Climate Hazards InfraRed Precipitation with Stations (CHIRPS) et de l'humidité relative dérivée d'ERA5, à partir desquelles ont été dérivés les déficits de pression de vapeur (VPD) et les températures maximales du thermomètre-globe mouillé (WBGTmax).
De grands ensembles CMIP6 issus des scénarios SSP 245 et SSP 585 (Shared Socioeconomic Pathway) ont été utilisés pour développer des champs delta quotidiens haute résolution (0,05°) pour 2030 et 2050.
