.. role:: rstblue .. role:: rstgrey .. role:: rstgreen ================ NEMO Ocean Model ================ NEMO_ (Nucleus for European Modelling of the Ocean) is a state-of-the-art modelling framework of ocean related engines for oceanographic research, operational oceanography, seasonal forecast and [paleo]climate studies. The NEMO ocean model has 3 major components: - :rstblue:`OPA` is fundamental to all users by modelling the ocean [thermo]dynamics and solving the primitive equations; - :rstgrey:`LIM` for sea-ice simulates ice [thermo]dynamics, brine inclusions and subgrid-scale thickness variations; - :rstgreen:`TOP-PISCES` models biogeochemistry with TOP for the on/offline oceanic tracers transport and PISCES for the biogeochemical processes. These physical engines are described in their respective `reference publications`_. They are complemented by a 2-way nesting software (AGRIF_) and a versatile data assimilation interface with 3 different modules (linear-tangent TAM, observational operators OBS, and increment ASM). ------------ Applications ------------ | Distributed under CeCILL license (GNU GPL compatible - see ``LICENSE``), the framework offers several builtins reference configurations to check your computing architecture and evaluate the model skills and performances (``./cfgs``). | The end user could also find some idealized test cases on the web to serve as examples and to study particular processes. A set of tools is also provided to setup your own configuration and [pre|post]process your data (``./tools``). ------- Options ------- For writing diagnostics in a efficient way, NEMO make use of XIOS_ server which controlled the outputs using XML input file. To enable Earth system modelling, NEMO can be interfaced via OASIS_ coupleur to external components such as atmospheric models or alternative models of sea-ice or biogeochemistry. ------------- Documentation ------------- The NEMO reference manual can be generated from the LaTeX source code (``./doc``), either in PDF or in HTML format, but it mights require some additionnal installations. In any case, both formats are available online on the `NEMO website`__. --------------------- Community development --------------------- | The NEMO Consortium gathering 6 European institutes organises the sustainable development in order to keep a reliable evolving system since 2008. | It defined the multiyear development strategy which is implemented by the NEMO System Team. -------- Acronyms -------- AGRIF Adaptive Grid Refinement In Fortran LIM Louvain-la-Neuve Ice Model OPA "Océan PArallélisé" (french) PISCES Pelagic Interactions Scheme for Carbon and Ecosystem Studies TAM Tangent Adjoint Model TOP Tracers in Ocean Paradigm XIOS XML Input Output Server ---- .. _AGRIF: http://agrif.imag.fr .. _Forge: http://forge.ipsl.jussieu.fr/nemo .. _NEMO: http://www.nemo-ocean.eu .. _OASIS: http://verc.enes.org/oasis .. _reference publications: http://www.nemo-ocean.eu/bibliography/documentation .. _XIOS: http://forge.ipsl.jussieu.fr/ioserver .. __: NEMO_
