= Coupling with other models (OASIS, SAS, ...)

NEMO currently exploits OASIS-3-MCT to implement a generalised coupled interface ([https://forge.ipsl.jussieu.fr/nemo/doxygen/node50.html?doc=NEMO Coupled Formulation]). It can be used to interface with most of the European atmospheric GCM (ARPEGE, ECHAM, ECMWF, Ha- dAM, HadGAM, LMDz), as well as to WRF (Weather Research and Forecasting Model), and to implement the coupling of two independent NEMO components, ocean on one hand and sea-ice plus other surface processes on the other hand ([https://forge.ipsl.jussieu.fr/nemo/doxygen/node46.html?doc=NEMO#SECTION001023000000000000000 Standalone Surface Module - SAS]).

To enable the OASIS interface the required compilation keys are '''key_oasis3''' and '''key_coupled'''. The parameters to set are in sections ''&namsbc_cpl'' and in case of using of SAS also in section ''&namsbc_sas'' .
