Model Description

IPSL-CM5 is developed by IPSL, includes 5 component models representing the Earth System climate and its carbon cycle: LMDz (atmosphere), NEMO (ocean, oceanic biogeochemistry and sea-ice), ORCHIDEE (continental surfaces and vegetation), and INCA (atmospheric chemistry), coupled through OASIS. IPSL modelling system also includes an I/O library (IOIPSL), an assembling and  compiling environment (modipsl), an execution environment (libIGCM) and a set of post-processing tools. IPSLESM, available in different configurations at different resolutions, is in permanent evolution to reflect state-of-the-art numerical climate science. 80 IPSLESM users are registered in IPSL and associates laboratories while about 200 persons use one or more components separately. IPSL-CM5 is used in about 50 European projects and more than 550 projects access its IPCC result database.
