 * _NEMO_ (“Nucleus for European Modelling of the Ocean”) is a framework of ocean-related engines. Within NEMO, the ocean engine is interfaced with a sea-ice model (SI3), passive tracers and biogeochemical models (TOP) and, via the OASIS coupler, with several atmospheric general circulation models. It also supports two-way grid embedding by means of the AGRIF software. For more information, please refer to the [nemo website](https://www.nemo-ocean.eu/). Since January 2019, The version of Nemo passed to 4.0.
 
-* _XIOS_ has been developed by LSCE-IPSL, it supports I/O writing of the simulations (use of xml libraries), the simulation of the model is simulated apart on different processes. Its use thus makes it possible to better manage the tuning of different number of I/O processes. If this tool is used as a server (separate processes allocated for writing (detached mode)), it makes it easier to work on the configuration parameters because there is no need to recompile each time. It also allows you to create new output files, new variables from those already referenced and to apply different time filters to them.
