تم تطوير مجموعة بيانات CHC-CMIP6 بشكل صريح لدعم تحليل المخاطر المتعلّقة بالمناخ خلال الماضي القريب وفي المستقبل القريب.
تحتوي مجموعة بيانات توقعات المناخ هذه على بيانات عالمية يومية مقسّمة إلى شبكات للفترات المرصودة (1983-2016) والمتوقّعة (2030 و2050) لاستخدامها في تحديد ورصد الظواهر الجوية المائية القصوى. تحتوي مجموعة البيانات على شبكات عالمية يومية عالية الدقة (0.05 درجة) لمنتج درجة الحرارة Climate Hazards InfraRed Temperature with Stations (CHIRTS-daily)، ومنتج هطول الأمطار Climate Hazards InfraRed Precipitation with Stations (CHIRPS)، والرطوبة النسبية المستمدة من ERA5، والتي تم منها استخلاص Vapor Pressure Deficits (VPD) وأقصى درجات حرارة Wet Bulb Globe Temperatures (WBGTmax).
تم استخدام مجموعات كبيرة من نماذج CMIP6 من سيناريوهات "المسار الاجتماعي والاقتصادي المشترك" (SSP) 245 وSSP 585 لتطوير حقول دلتا يومية عالية الدقة (0.05 درجة) لعامَي 2030 و2050.
