Dynamical Cores Workshop IS-ENES Dynamical Cores Workshop Lecce, Italy December 14th -16th 2011 InfraStructure for the European Network for Earth System modelling IS-ENES Sylvie JOUSSAUME, CNRS-IPSL, Coordinator

IS-ENES : Infrastructure for ENES EU FP7 project « Integrating Activities » 2009-2012 18 partners – coord IPSL 7.6 M€ Infrastructure : Models and their environment Model data Interface with HPC ecosystem Users : The ENES community Regional climate models Impact studies ENES Portal http://verc.enes.org Europe : 6 global climate models CMCC, COSMOS, EC-Earth, Hadley, IPSL, Meteo-France

http://is.enes.org/ Objectives: Integration of the European ESM community ENES strategy, exchange of expertise/training, portal Development of ESMs service on common tools and model components, common evaluation international standards Prepare for high-end simulations interface with PRACE, improve model performance Foster application of ESM simulations for climate change impacts dissemination of model results (CMIP5), interface with decision makers and users

Workshop on dynamical cores ENES Strategy : Prepare next generation of climate models able to run on many-core HPC – peta/exascale Issue : need to revisit dynamical cores Europe: on-going national projects ICON (DE), Gung-Ho (UK), Dynamico (FR) … G8 project : ICOMEX (prepared within ENES on European side)
