Background
COACh is an international research school for Cooperation on Oceanic, Atmospheric and Climate Change Studies, a collaboration of the Netherlands Centre for Climate Research (KNMI, IMAU, RIVM) and the Max-Planck Institut fuer Meteorologie in Hamburg and MPI fuer Chemie in Mainz.

PRISM (PRogramme for Integrated earth System Modelling) is a consortium of European institutes collaborating to create an efficient and effective infrastructure for climate and earth-system modelling.

Rationale
Reliable (regional) climate change predictions cannot be achieved without enhanced European collaboration. PRISM has been set up to foster this collaboration, and to provide an infrastructure which allows joint multi-century simulations resolving important climatic features, physical processes and regional details. PRSIM will also make ensembles of integrations in order to estimate the impact on climate predictions of uncertainties in initial conditions and model formulation.

As a first step PRISM needs to assess the science of climate simulation in Europe.

Name of the summer school
Climate modelling in Europe

Place
Les Diablerets, Switzerland

Dates
25/6/01 (arrival in the evening) - 29/6/01, 13:00

Funding

• To review the status of Climate and Earth System Modelling in Europe:
  What models are available in Europe? What are the scientific requirements? For each sub-component - also for the coupled models - what are the arguments in favor of preserving or not a diversity of models; what is an adequate validation; what can we expect in terms of new development; what may differentiate the existing models, and the models to be, in terms of coupling with other sub-components?
• To present the PRISM project
• To formulate scientific requirements for the PRISM model infrastructure
• Foster the interaction between PRISM and external groups/users

• Three and a half days
• Mostly general invited lectures (on component models and the coupled system)
• Friday morning Summary & Discussion: What are the scientific problems we will want to address with the coupled models that the PRISM modelling structure will allow us to assemble (beyond the PRISM demonstration runs)? Did we include in PRISM all relevant components to address these scientific questions? What is the definition of a "component"? Is the partitioning of the Global Climate System into components done in PRISM the relevant one? What are the consequences for the PRISM project?

Number of participants
About 40 - 60 by invitation (2 per PRISM partner plus a number of outsiders)

Financial organisation
The financial coordination will be with MPI Hamburg (Karin Niedl, niedl@dkrz.de). Lecturers will be fully reimbursed, in principle. PRISM participants will be reimbursed travel costs up to DM 1500 pp plus board and lodging up to about DM 120 - 150 per day. Additional participants will have to bear their own costs.

Accommodation
Meeting place (Hotel des Diablerets, Les Diablerets, Switzerland). Board and lodging preferably in Hotel des Diablerets (40 to 59 rooms).

Proceedings
Euroclivar format, i.e. a few pages of general conclusions + abstracts of all papers
