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.

IPSL Seminar – V. Balaji – 20/12/2018

Machine learning and the post-Dennard era of climate simulation Conventional computational hardware has reached some physical limits: the phenomenon known as ‘Dennard scaling’ gave rise to Moore’s Law, and many cycles of exponential growth in computing capacity. The consequence is that we now anticipate a computing future of increased concurrency and slower arithmetic. Earth system […]
