CMIP6, CORDEX, and related activities in Hamburg/Germany Stephanie Legutke, DKRZ/Data Management COSMO CLM User Meeting, Offenbach, 6-7 March 2015

De-centralized CMIP6 design DECK (Diagnosis, Evaluation and Characterization of Klima) continuity: provide basis for ensembles across CMIPs qualifies for CMIPn archive (ESGF) AMIP pre-industrial control 1% p.y. CO2 increase abrupt 4xCO4 According to the community preferences captured in a wide survey after CMIP5, the CMIP6 design is more de-centralized than CMIP5. Also, CMIP6 is designed to support the continous model development process, in contrast to CMIP5 where all activities were managed by the CMIP5 project lead and a huge bulk of experiments was performed centralized in time (2011) and space (DKRZ) and group (DKRZ/MPI-M). 3 broad scientific questions (for CMIP simulations): Res., Syst.Biases, Var.... 6+1 challenges: Clouds, Cryos., Extr., Reg. Cl., Reg. SeaLevel Rise, Water, CORDEX CMIP6 endorsed diagnostic MIP application CMIP6 evolving external forcing, period historical CMIP6-endorsed MIPs run autonomously ...

COSMO CLM User Meeting, Offenbach, 6-7 March 2015 CORDEX in CMIP6 CORDEX applied as diagnostic CMIP6-endorsed MIP (authored by Bill G., Filippo G.) Definition of diagnostic MIP: does not require additional ESM experiments data requests only from DECK/CMIP6/CMIP6-endorsedMIPs All-MIPs proposals scientifically revised and harmonized with other MIPs http://www.wcrp-climate.org/modelling-wgcm-mip-catalogue/modelling-wgcm-cmip6-endorsed-mips Final proposal to be submitted 31 March 2015 MIP Endorsement by CMIP Panel and WGCM co‐chairs, 30 April 2015 MoU being prepared: CORDEX data will be accessible with the CMIP6 ToU (i.e. unrestricted) CORDEX SAT meeting 25-27 Feb 2015 discussing details ??? s.b.
