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, the LIM model for the sea-ice, the ORCHIDEE model for terrestrial surfaces, and PISCES for the marine biosphere. 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 under development and test.

Withdrawal from CMIP6

Due to significant issues recently found in their model components, IPSL CMC has decided to stop the production of its pre-industrial spinup climate simulation that started on March 29th. Given the tight schedule it was operating on and the severity of the issues found, IPSL CMC has no other option but to withdraw its participation […]


Launch of CMIP6 simulations

IPSL CMC has launched its first CMIP6 simulation today after more than two years of model development, model tuning and preparation of an optimized workflow for the output data. A large number of simulations from the DECK and the various Model Intercomparison Projects will now be performed on a special HPC allocation provided by GENCI. […]
