NEMO (Nucleus for European Modeling of the Ocean) is a state-of-the-art modeling framework for oceanographic research and operational oceanography. The core of the system is a primitive equation model applied to both regional and global ocean circulation. It is intended to be a flexible tool for studying the ocean, the sea-ice and its interactions with the others components of the earth climate system (atmosphere, land-surfaces, vegetation). NEMO is written in Fortran 90 and is parallelized with a domain decomposition using MPI library. All outputs are done with NetCDF library
