PUNI Handbook – Methods for Providing and Utilizing Uncertain Multi-model Based Information on Freshwater Related Hazards of Climate Change

In this handbook, we inform about provisioning and utilization of the MME-based global-scale quantitative estimates of freshwater-related hazards of climate change that are freely available on the CO-MICC portal (www.co-micc.eu). We refer to the corresponding methods as PUNI (Providing and Utilizing eNsemble Information) methods, which encompass appropriate ways for characterizing and dealing with the uncertainty of future hazards. A major goal regarding information provisioning is to represent uncertainty quantitatively in a way that is both scientifically correct and meaningful to the diverse users of the hazard information. A major goal regarding the utilization of the information is to identify approaches for integrating information with quantified uncertainty into (participatory) assessments of water-related climate change risks and adaptation options, also considering the rough representation of local conditions by global hydrological models (GHMs).
