The Institut Pierre-Simon Laplace (IPSL) is a federation of research laboratories devoted to study the climate system and the global environment. Since 1995, the IPSL Climate Modelling Centre (IPSL-CMC) develops and uses climate models in order to improve our understanding and knowledge of the climate system, its current characteristics and its past and future changes.

Many aspects of the climate system are studied at IPSL and IPSL-CMC is one of the few climate modelling centres worldwide that develop most aspects of its Earth System Model (ESM). Such a model represent the different components of the climate system and their interactions. The IPSL Earth System Model comprises of the LMDz model for the atmosphere, the INCA and REPROBUS models for atmospheric composition, the NEMO model for the ocean, including ocean dynamics (NEMO-OCE), sea-ice (NEMO-LIM) and ocean biogeochemistry (NEMO-PISCES), and the ORCHIDEE model for terrestrial surfaces. The IPSL climate model uses the OASIS coupler and the powerful XIOS input/output server. A new dynamical core for the atmosphere, known as DYNAMICO, is now coupled to the atmospheric physics and forms our next generation model.

Publication of CMIP6 data

Another milestone has been reached with the publication of over 200,000 CMIP6 datasets by the IPSL group for its IPSL-CM6A-LR model. See the ESGF CMIP6 Data Holdings for more statistics. The published datasets include the piControl, historical and scenario experiments, along with many experiments from various Model Intercomparison Projects (MIPs). All datasets can be accessed […]
