IPSL-CM6 model of IPSL (Institute Pierre-Simon Laplace)

The IPSL Climate Modelling Centre (IPSL-CMC) is hosting a collaborative effort to develop climate models, study the natural variability of climate, its past, current and future changes, and the anthropogenic influences on it. Numerical models of the individual components of the climate system are developed in the IPSL laboratories: atmosphere, ocean, continental surfaces, marine and terrestrial ecosystems, atmospheric chemistry. Physical, chemical and biogeochemical processes are considered. IPSL-CMC brings together the different teams of the IPSL laboratories that have modelling activities but has also dedicated staff to develop the IPSL integrated model of the Earth system. Overall, IPSL-CMC involves more than 80 engineers and scientists. A larger group of about 200 people use its results and benefit from the availability of the simulation data.

IPSL-CM6A-LR is the latest version of the IPSL climate model. This model contributes to the Climate Model Intercomparison Project Phase 6 (CMIP6). In addition to the physical atmosphere-land-ocean-sea ice model based on the LMDz, ORCHIDEE, NEMO (including the LIM and PISCES subcomponents) models, it also includes a representation of the carbon cycle. Modules for interactive stratospheric chemistry (REPROBUS) and tropospheric chemistry with aerosols (INCA) can be activated. The IPSL climate model uses the OASIS3-MCT coupler, the powerful XIOS input/output server as well as libIGCM running environment library.

Main model components

  • LMDZ: representing the atmosphere

  • ORCHIDEE: representing the continental surfaces

  • NEMO: representing the ocean, sea-ice and biogeochemical processes

  • INCA: representing the atmospheric (tropospheric) chemistry and aerosols
