Technical note on MODIPSL and IPSLCM4_v1



MODIPSL is a tool developed (in Korn Shell and Python) by IPSL modelling pole engineers with the aim of providing a common access and a common interface to each of the IPSL different models.

The IPSL "earth system model", results from the different models developed by four of the IPSL laboratories, LMD, LODYC, LSCE, SA, and from collaborations with LGGE for the high latitudes climate, LOA for the modelling of direct and indirect effects of the aerosols, UCL ASTR for the new version of the sea-ice model, and CERFACS for the coupler.
Successive versions of the Global Coupled model have been developed since 1995 (IPSL_CM1, IPSL_CM2, IPSL_CM3).

Currently, the last version of the Global Coupled model is called IPSL-CM4. Also, its first development is called IPSLCM4_v1
It Integrates all the technical improvements and scientific comprehensions which come from the use of the preceding models.
The code and its environnement are available via the general structure called MODIPSL.
