Strategy of modelling at IFREMER  
====================================

  *  MARS model is implemented for research and operational interests over the three metropolitan basins : the Channel, the Bay of Biscay and the North-Western Mediterranean Sea.

  *  Large scales are treated by operational institutes (MFS, MERCATOR), that provides MARS with initial fields and open boundary conditions.
  *  For the coarsest configuration (rank0), open boundary conditions for tides come from  different data sets : FES2004, FES1999, Schwiderski 
  *  If required, models are coupled offline or online (AGRIF package). 
  *  A configuration can be splitted into several ranks, the spatial resolution increasing with ranks
  *  More than 30 configurations are implemented by Coastal Environment Laboratories
