This webiste displays near real-time monitoring of global super drought and publishes global super drought dataset. Super drought concept and associated Comprehensive Multiscalar Index (CMI) are developed to describe the overall extremity of multiscalar drought. Super drought refers to the simultaneous occurrence of extreme droughts at multiple time scales. The physical significance of super drought represents compound water deficits in all parts of hydrowater resources. CMI is a powerful measure to determine the overall rarity of multiscalar drought and recognize super drought.
