  1. COSMOSCommunity Earth System Modelsand itsregional pilot study BALTEXDaniela Jacob

  2. Outline • Motivation • COSMOS • Baltex as a pilot study

  3. Motivation During the 16th Baltex Science Steering Group meeting the idea was born to implement Baltex as a pilot study of COSMOS

  4. Outline • Motivation • COSMOS • Rational, Initiative, Structure, Science • Baltex as a pilot study

  5. Time has come to integrate different model components into a Earth System Modeling framework This Community Earth System Model is a tool to integrate knowledge and to address cross-cutting issues, including the interactions between the physical climate system and biogeochemical cycles. Rationale (1)

  6. COSMOS benefits from experience developed by different modeling groups in Germany and abroad It is a community initiative, and involves top-of-the-line model components It requires substantial computer resources It should be designed flexible, portable and user-friendly, and is a joint venture between scientists and software engineers Rationale (3)

  7. It is designed to address global as well as regional issues It should receive an international recognition, and be comparable to similar initiatives developed in other European countries, the US and Japan. It should contribute to European research efforts Rationale (3)

  9. COSMOS will be developed through human and financial resources provided by the partnership [Max Planck Institutes of Hamburg (Project Leader), Jena and Mainz, and PIK], with an equally important participation of other groups and institutions. The Initiative

  10. Management Structure • Steering Committee • Scientific Advisory Group • Project management • Working groups Supervising Board Scientific Advisory Board Project Management Working Groups

  11. Steering CommitteeOversees the evolution of the project, provides resources, and decides on the external co-operation with other institutions. Scientific Advisory Group Advises the project by main responsible scientists of the contributing institutions and external, independent advisors. Project managementResponsible for the planning of the total development process, the synthesis of the COSMOS development, and the scientific evaluation of the model. Working groupsco-chaired by 2 scientists Management Structure

  13. 2 meetings of the boards as well as the community Several working group meetings Workshop on data and model validation Meetings

  14. Prototype Experiment Nr.1 1000 year transient climate experiment Leading Scientist: E. Roeckner Co-laborators: R. Sausen / M. Dameris, M. Schulz, S. Yang, B. Steil, U. Mikolajewicz, K. Schnitzler, U. Ulbrich, C. Heinze, S. Gualdi, P. Ruti, M. Wild

  15. Prototype Experiment Nr.2 Regional patterns of climate change Leading Scientist: D. Jacob Co-laborators: W. May, E. Schaller, E. Kjellstrom, U. Ulbrich, M. Botzet, M. Wild

  16. Reconstruction of the past 50 years/ IPCC scenarios/ evaluation of COSMOS1 What additional consequences come up by the coupling of everything ? Regional modelling: hydrological cycle/extreme events (experiment will be designed) Coupling of nitrogen and carbon cycle: What is the effect of nitrogen on the carbon cycle? Polar carbon release: What are the consequences of high latitude methane release in a warming world? The abiotic world: How would it look like? Important and urgent topicsdefined on the 2nd Annual Meeting, Lüneburg, March 2004

  17. • atmospheric dynamics and physics (ECHAM5) • aerosols (HAM/M7) • atmospheric chemistry (MECCA) • land vegetation (JSBACH) • land atmosphere exchange (XTSURF) • hydrology, lateral/vertical (HD/multi layer) • ocean/ice (MPI-OM/embedded) • ocean biogeochemistry (HAMOCC + Dyn. Green Ocean Model) • coupler (OASIS3) Regional components not jet fully defined COSMOS 1

  18. The development and verification process will involve several partners. Co-operation agreements shall specify the mutual obligations of the individual partners within the development and verification of COSMOS. Co-operation agreements

  19. The models developed in the partnership will be made available to the Scientific Community, once these models are sufficiently evaluated by the model developers. Working groups will be responsible for the development, integration and evaluation of the codes.   Working groups will be open to scientists who would like to contribute to the development or use of the model. Guiding Principles

  20. The integration of the model components will be performed at the Max Planck Institute for Meteorology in close cooperation with the other partners The model will be documented and distributed through a web system maintained by the Max Planck Institute for Meteorology. Guiding Principles

  21. A community meeting will be organized every year (1) to review progress in model development, (2) to plan future development, (3) to discuss scientific questions to be addressed by the model system. Guiding Principles

  22. Next Annual Meeting in Lüneburg, Germany 2. – 4. March 2005 http://cosmos.enes.org/

  23. BALTEX and COSMOS • Will BALTEX be the first regional pilot project (???) • Baltex grid project (A. Lehmann, D. Jacob) • Share resources (model data, observations and expertise) through international collaborations • Concentrate on Baltex-Bridge period (1999-2004) • Use coupled modelling systems RCAO and BALTIMOS

  24. The Baltex Grid Examples of potential collaborations • Investigation of air-sea fluxes (compare observations against model results) • Local dynamics of a region (provide boundary conditions for high resolution model) • Analyses of extreme precipitation events (observations versus coupled model results9 • Sea ice evolution (improvement of the sea ice models)
