1. Climate Forecasting Unit Melanie Davis (IC3) & Jean-Pierre Ceron (Meteo France) mdavis@ic3.catmdavis@ic3.cat, jean-pierre.ceron@meteo.fr EUPORIAS WP41 Climate Information and Decision Making Starts: M25 (November 2014) Ends: M43 (May 2016) EUPORIAS General Assembly, Toulouse, 21 st October 2014

2. Climate Forecasting Unit Tasks Information input from WP12 stakeholder interviews and RT2 climate forecasts and case studies T4.1.1 (All): 5% time Choose a decision making chain and its relevant economic model(s) and knowledge system. Understand the risks (climate and non climate) of the decision processes identified. T4.1.2 (All): 5% time Assess impacts and risk management strategies throughout the DMPs over S2D timescales. LEADING TO... T4.1.3 (All) : 20% time - Define a methodology to evaluate the DMPs that are affected by climate. T4.1.4 (All): 40% time - Evaluate the relative weight of climate information in the relevant DMP. LEADING TO... T4.1.5 (UNIVLEEDS, IC3, MF, WHO Euro, and WFP): 15% time Define standardised protocol(s) for evaluating DMP T4.1.6 (DWD, MF, WHO Euro, and WFP): 15% time Review the WMO Regional Climate Centre-network information and its relevance to the DMP: Information input from WP 1.1, Task 1.1.3.

5. Climate Forecasting Unit Value of Climate Services – quantitative cost/benefit analysis Impact of s2d probabilistic forecasts on the decision making process – quantitative. Role of Climate Services – qualitative: the human dimension Effect of Climate Services on stakeholders decisions. - Risk of not acting: if high, would you act regardless of the forecast? - Use of a probabilistic forecast/interpretation of uncertainty - Test using a “Placebo”?

Role of Climate Services – qualitative: the human dimension Effect of Climate Services on stakeholders decisions – qualitative. Redefine Climate Information Assessment of the provided information on the decision making process - Data needs and its communications (risk alongside uncertainty) - Visualisation techniques → Standardisation? Strategy/protocol for providing information?
