Welcome

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.

New PRACE allocation for IPSL CMC

Myriam Khodri and her team have been awarded ~40 millions hours of HPC as part of the PRACE 21st call for proposals (October 2020 to September 2021). Their proposal, ASSIM2K, aims to assess climate models’ ability to reproduce natural climate variations. Proxy records (corals, speleothems, etc.) documenting the last 2000 years (2K) provide evidence for […]
