2. What is EUCLIPSE? A (likely) European Commission (EC) sponsored collaborative project Plans are build on the CFMIP2/GCSS proposals View it as capacity building around the CFMIP2/GCSS plans Starting date : Fall 2009/Early 2010 Duration: 4 years.

3. Budget Total Budget: 5 Million Euro Eu Sponsored: 3.5 Million Euro Involved Institutes:1.5 Million Euro Mainly used to hire personel: 42 man year total

4. Involved Institutes

5. TOPICS

6. WP1: Evaluation techniques and climate model experiments Largely overlapping CFMIP2/GCSS Extra resources for data hosting and dissemination (DKRZ) Led by: George Tselioudis (Athens)

7. WP2: Climate Model Evaluation and Analysis Extra: cloud aerosol evaluation subproject (Quaas MPI Hamburg) subproject on evaluation of polar clouds (Svensson, Stockholm) Led by: Sandrine Bony (IPSL)

8. WP3: Process Evaluation Analysis Largely overlapping with present activities discussed in this workshop Some extra emphasis on ESM evaluation on specific locations: Cloudnet, ARM AMMA,GPCI Led by: Stephan de Roode (TU Delft)

9. WP4: Metrics and diagnostics for narrowing uncertainties in clolud climate feedback Extra: NWP related activities to identify cloud representation biases: Initial tendency techniques. Transpose-AMIP type of experiments. model experiments nudged to reanalysis data. Led by: Bjorn Stevens (MPI Hamburg)

10. Outreach Activities 1 or 2 Summerschools Outreach of model and observational data. Publications, Websites, Brochures etc……

11. Conclusions View EUCLIPSE as a “funded organic outflow” of CFMIP2 that will increase capacity to enlarge the chances of success for the CFMIP2/GCSS plans! (like EUROCS vs GCSS in the past)
