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

2. 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).

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
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 Feb 2015 discussing details

5. Differences to CORDEX in CMIP5
no priority domain (prelim. info Bill G.)
possibility to apply for new domain
2-3 sub-domains may be defined for each domain with target resolution 2-3 km for pilot/flagship study
non-hydrostatic, cloud resolving? (SAT May 2014, Feb 2015)
issue: data access via ESGF
no downscaling of decadal ‚predictions‘ or AMIP any more
including ESD

6. Differences to CORDEX in CMIP5 cont.
Emerging issues for discussion Possible increased focus on region-specific forcing or single-forcing effect (DAMIP}
Effects of land-use change collaboration with the LUCID project
Effects of aerosols
Regional attribution
EarthSystem coupling

7. CORDEX forcing data request
Provision of CORDEX forcing data depends on the willingness to participate in a MIP
Entry criteria for ScenarioMIP:
SSP5-8.5, SSP1/2-6.0, SSP1-2.6
Entry criteria for DAMIP:
2nd an 3rd historical
GHG-only
NAT-only
AER-only
and on the willingness to provide the large-volume data

8. CMIP Organization and Governance
WGCM co-chaired by S. Bony and C. Senior
Ensure communication between MGs, CMIP Panel, WIP, WCRP Gr.Chall., core projects
Organize the review of MIP proposals for CMIP6 endorsement
CMIP Panel chaired by V. Eyring J. Meehl, B. Stevens, R. Stouffer, K. Taylor
Coordinate CMIP, DECK, and CMIPn historical simulation
Approve endorsement of MIPs, scientific content of CMIP data request
Facilitate communication between MIPs, MGs and WIP
COSMO CLM User Meeting, Offenbach, 6-7 March 2015
