Modelling the Earths Climate System - Data and Computing Challenges

SESSION: HPC Applications and Society

EVENT TYPE: Keynote and Invited Talks

TIME: 3:30PM - 4:15PM

SESSION CHAIR: Yoshio Oyanagi

Presenter(s):Sylvie Joussaume


Climate models are used to assess mitigation and adaptation strategies for climate change. The international community has just completed an unprecedented coordinated set of experiments, the Coupled Modeling Intercomparison Project (CMIP5), to which the European Network for Earth System Modelling ENES has contributed with 7 global climate models. These experiments have triggered a new way to manage the Petabyte distributed datasets produced and widely used to study climate change and its impacts. The European IS-ENES infrastructure contributes to this international challenge. The future of climate modeling highly depends on available computing power: ensemble of prediction experiments, increase of resolution to better represent small scale processes, complexity of the Earths climate system, duration of experiments to investigate climate stability, are all limited by computing power. Massively parallel computing starts to address resolution increase and ensemble runs but still raises a number of issues as emphasized by the ENES infrastructure strategy.
