O CHC-CMIP6 foi desenvolvido explicitamente para apoiar a análise de riscos relacionados ao clima no passado recente e no futuro próximo.
Esse conjunto de dados de projeção climática contém dados globais e diários em grade para os períodos de observação (1983 a 2016) e projeção (2030 e 2050) a serem usados na identificação e no monitoramento de extremos hidroclimáticos. O conjunto de dados contém grades globais diárias de alta resolução (0, 05°) do produto de temperatura Climate Hazards InfraRed Temperature with Stations (CHIRTS-daily), do produto de precipitação Climate Hazards InfraRed Precipitation with Stations (CHIRPS) e da umidade relativa derivada do ERA5, de que foram derivados os déficits de pressão de vapor (VPD) e as temperaturas máximas de bulbo úmido e globo (WBGTmax).
Grandes conjuntos do CMIP6 dos cenários de trajetória socioeconômica compartilhada (SSP, na sigla em inglês) 245 e 585 foram usados para desenvolver campos delta diários de alta resolução (0,05°) de 2030 e 2050.
