4. IPSL Models for CMIP6 IPSL-CM6 ESM AOGCM: Two resolutions:
LR : Atm: 2.5x1.5° (144x144) L Oce: 1° L75
MR : Atm: 1.3x0.6° (280x280) L Oce: 0.25° L75
Configurations
standard: physical + carbon cycle + prescribed aerosol and ozone
standard with interactive aerosol
Atmosphere only: High resolution
HR : Atm with new dynamical core DYNAMICO 0.5°
IPSL-CM5A-AerChem
Continuity with IPSL-CM5A used in CMIP5
Interactive chemistry and aerosols
VLR : Atm: 3.75x1.9° (96x95) L Oce: 2° L31

5. Configuration and hierarchy of IPSL Models
IPSL-CM6 ESM
Configurations:
standard: physical + carbon cycle + prescribed aerosol and ozone
standard with interactive aerosol
 High interest in:
Consistency between past-present-future
“Realistic” versus idealized experiments and configurations (including aquaplanet)
Stand-alone model vs coupled model
IPSL-CM5A-AerChem
Dedicated model version for complex, interactive chemistry and aerosol: robust and stable physics, low resolution

Start simulations with IPSL-CM6.1-LR and IPSL-CM5A-AerChem
End 2016
Start publication of results
2017
Simulations with IPSL-CM6.1-LR and start with IPSL-CM6.1-MR
2018:
IPSL-CM6-HR and possible second version IPSL-CM6.2-LR

8. CMIP6: Feedback from CNRM-CERFACS

L. Terray and C. Cassou2
1 CNRM-GAME, Toulouse, France
2 CERFACS, Toulouse, France

9. Introduction: CNRM-CM5 (CMIP5)
CNRM-CM5 : ARPEGE-Climat v5 (diag. physics) TL127L31 + NEMO3.2 ORCA1L42 + SURFEX + TRIP1° (Voldoire et al., Clim. Dyn, 2013)
Meteo-France’s operational seasonal prediction based on CNRM-CM5
Contribution to CMIP5 : ~9000 years for CMIP5 (centennial, CNRM), 4000 years (decadal, CERFACS)
Participated to CFMIP, PMIP, D&A large ensemble (30 historical exps)
Derived versions :
CNRM-ESM1 : CNRM-CM5 + carbon cycle
CNRM-CCM : CNRM-CM5 including stratospheric + tropospheric chemistry (60 vertical levels in the atmosphere)
CNRM-CM with interactive Greenland ice-sheet

10. Plans for CNRM-CM6 CNRM-CM6 AOGCM:
low resolution (LR) : TL127L91 + NEMO3.6 ORCA1L75 + SURFEX + TRIP0.5°
 for D&A, ScenarioMIP… ARPEGE-Climat v6 (prognostic physics)
high resolution (HR): Atm: TL359L91 / Oce: ORCA025L75
for HighResMIP…
2015:
CNRM-CM6-LR available by late 2015 (preliminary version performing already better than CNRM-CM5 already available, a bit more tuning is still needed to improve the model further)
2016:
- CNRM-ESM LR available by mid 2016
- CNRM-CM6 HR + CNRM-ESM2 HR available by late 2016
DECK + CMIP6 Historical Simulation (CNRM-CM6-LR + CNRM-ESM2-LR) by late 2016
AMIP simulations, OMIP, Land-Only simulations, DAMIP (LR) :
MIPs (all except PDRMIP, SolarMIP, VolMIP)

11. Plans for regional climate modelling
Based on Aladin-Climat model CORDEX actually managed outside CMIP
