1. The Future ENES Strategy – Toward a Foresight Document Jochem Marotzke Max Planck Institute for Meteorology (MPI-M) German Climate Computing Centre (DKRZ) KlimaCampus Hamburg

2. WP2/NA1: The future ENES strategy Task 1: Define the European strategy in climate and Earth system modelling Task 2: Prepare the ENES strategy with regards to the HPC-ecosystem Task 3: ESM Education - Developing a strategy Task 4: Dissemination Focus on Tasks 1 and 2 here

3. NA1 Task 1: European strategy in climate and Earth system modelling What does Europe need in terms of climate and Earth system modelling and prediction? How is Europe going to face the increasing demand for information on societal impacts? What will be the status of European climate and Earth system models 10 year from now? What kind of infrastructures are required ?

4. NA1 Task 1: European strategy in climate and Earth system modelling NA1 task 1 will deliver the Foresight position paper on “The ENES strategy and its Implementation” (Deliverable D 2.4, month 36)

5. NA1 Task 1: European strategy in climate and Earth system modelling Start with large workshop to brainstorm & define the key questions to be addressed by dedicated working groups. (Milestone 2.1, month 6) Working groups to elaborate elements of strategy End of the task (month 34, with 2 nd IS-ENES General Assembly): Large workshop to discuss and synthesise conclusions from working groups Establish the Foresight position paper on “The ENES strategy and its Implementation” 40 k€ available to invite about 20 to 25 non IS-ENES partner scientists to prepare the ENES future strategy

6. NA1 Task 2: Strategy for ENES & HPC Ecosystem Prepare the ENES community for PRACE and DEISA2 Define the needs of the climate community Define climate benchmarks Organise the interface between PRACE and the climate scientific community Update the scientific case in the field of climate science When facilities are available, organise the most advanced and adapted experiments to benefit from such facilities. M2.2 (Task 2, mo 6): First list of requirements for PRACE

7. NA1 Task 2: Strategy for ENES & HPC Ecosystem Prepare for future HPC architectures Establish the European strategy to develop the next generation of climate and Earth system models Elaborate the ENES strategy with regards to the HPC-ecosystem M2.4 (Task 2, mo 30) Elements for the ENES strategy on the HPC-ecosystem to feed back into Task 1

8. How to get to the Foresight document? We have committed to the content and the delivery date (month 36) Foresight must have elements of Climate and Earth system science Communication with users of this science Infrastructure: HPC and other technical Infrastructure: Workforce Other? We need a relatively small core writing team. Volunteers?
