  • Person in charge: Juliette Mignot (+ Didier Swingedouw et Eric Guyliardi)
  • Person doing the runs: Juliette Mignot, Didier Swingedouw
  • Model: IPSL-CM6-VLR
  • Number of years: TBC


  • Person in charge: Didier Swingedouw (didier.swingedouw@…)
  • See: for a full description of the experimental design.
  • Model: IPSL-CM6-LR
  • Simulations: using IPSL model, it is planned to perform the three experiments (stressFAF, heatFAF, waterFAF) from Tier1 for a total of 210 years of simulations (280 years if control has to be rerun). The main difficulty is to have 3D tendencies in the ocean as diagnostics outputs of the simulations. NEMO will be hopefully equipped with a key to allow such a requirement.



  • Person in charge: Laurent Li
  • See and for a presentation
  • Modèle: IPSL-CM6-LR
  • La premiere simulation est une simulation AMIP etendue sur la periode 1870/2013.
  • La deuxieme simulation utilisera le modele couple, mais une partie de la SST n'est pas libre, parce qu'elle sera relaxee vers les valeurs observees sur la periode 1870/2013. Les zones de relaxation sont AMO (Atlantique du Nord) et IPO (Pacifique tropical).
  • La troisieme simulation consiste a tester l'orographie, avec les effets mecaniques et thermodynamiques separes.
  • Le nombre total d'annees est de l'ordre de 500 ans (3/5 en mode couple, le reste avec atmosphere seule).

  • Persons in charge: Masa Kageyama, Pascale Braconnot , Myriam Khodri
  • 5 simulations: past1000, midHolocene, lgm, lig127k, midPliocene-eoi400
  • All simulations but past1000 are equilibrium runs: the simulations will be run to stable state, the last 100 to few hundred years will be processed and sent to ESGF.
  • Past1000: a single 1150 years (850-2000), after a short stabilisation run with 850 conditions ( a few hundred years)
  • Persons doing the runs: Pascale (midHolocene, lig127k), Myriam Khodri (past1000), Masa (lgm), Ning Tan (midPliocene-eoi400), Jean-Yves Peterschmitt
  • All PMIP4-CMIP6 simulations are Tier 1.
  • Model: IPSL-CM6-LR (Tier 1)
  • Planned timing of the simulations: past1000, midHolocene, lig127k can be started as soon as model version is frozen, lgm and midPliocene-eoi400 require more time for their set up but should start asap. The aim is to get our first results out for the PMIP conference at the end of September.

CMIP6 forcing datasets

A copy of ESGF input4MIPs data is on ciclad: /prodigfs/project/input4MIPs

Other forcing datasets are on ciclad: /home/oboucher/CMIP6

Description paper :

Greenhouse gases

Person in charge : Olivier Boucher

See for more information

We use /prodigfs/project/input4MIPs/UoM/GHGConcentrations/CMIP/UoM-CMIP-1-2-0/yr/ data

The data on curie are available from $R_IN/IGCM/ATM/GHG/CMIP6/historical

The README and extraction script is on ciclad: /home/oboucher/CMIP6/GHG

The GHG to be used are CO2, CH4, N2O, HFC134a-eq (fed to CFC11) and CFC12eq (fed to CFC12).

So in the end, we have 5 files for GHG for CMIP6 runs with IPSL-CM6

  • CO2_CMIP6_0000_2014.txt
  • CH4_CMIP6_0000_2014.txt
  • N2O_CMIP6_0000_2014.txt
  • CFC11eq_CMIP6_0000_2014.txt
  • CFC12eq_CMIP6_0000_2014.txt

Note that the CFCeq files have non-zero values for pre-industrial conditions because they include some natural species.

Chemistry and aerosols

Solar forcing

Person in charge: Olivier Boucher, Marion Marchand, Rong-Ming Hu

See for more information

The scripts, readme and data are on ciclad /home/oboucher/CMIP6/SOLAR

The solar forcing files are on ciclad /home/oboucher/CMIP6/SOLAR/OUTPUT

The data on curie are available from $R_IN/IGCM/ATM/SOLAR/CMIP6/v3.1

The time period of data file is from 1 January 1850 to 31 December 2299. We reprocessed the daily spectral solar forcing data into the data files with 2 and 6 wavebands for RRTM. We also added the variables of solar irradiance anomaly and fraction for the model inputs in a particular waveband. The netcdf files need to have the same number of days as the LMDz year that is run (either 360, 365 or 366 days). There is a flag ok_suntime_rrtm that can be activated but this only works for RRTM, flag_rrtm=1.

The average for piControl consists of the first two solar cycles after 1850 (as per CMIP6 protocol). The average for pdControl consists of a 1991-2010 average (not an official CMIP6 run).

Annual files are available for the historical and future period: where XXXX is the year. The files are for a Gregorian calendar (365 and 366 days according to the year).

There is also a scenario with a lower solar constant in 21st century for sensitivity study. This is not an official CMIP6 scenario though.

The solar forcing file is to be renamed in the running directory.

Tropospheric and stratospheric ozone

Person in charge: David Cugnet, Marion Marchand, Slimane Bekki with help from Thibaut Lurton

See for more information

Data are on ciclad : /prodigfs/project/input4MIPs/UReading/ozone/CMIP/UReading-CCMI-1-0

The data for CMIP6 on curie is available from $R_IN/IGCM/ATM/OZONE/UReading_2016/3D_14Fields/144x142x79

Volcanic aerosol

Persons in charge: Olivier Boucher, Myriam Khodri, Nicoas Lebas

See for more information

Data on ciclad: /prodigfs/project/input4MIPs/VOLC

The data for IPSL-CM6 on curie is taken from $R_IN/IGCM/ATM/STRATAERO/CMIP6/v1

There is a flag flag_aerosol_strato that has to be set to 2 to run with CMIP6 volcanic aerosol forcings.

The data are monthly latitude-altitude and are not interpolated temporally between months.
