This paper addresses scientific challenges related to high level implementation strategies that leads NEMO to effectively use of the opportunities of exascale systems. We consider two software modules as proof-of-concept: the Sea Surface Height equation solver and the Variational Data...

In this document is described the OceanVAR software (a three- dimensional variational data assimilation system, 3dvar) developed at the CMCC for use with the NEMO modeling system and SLA, ARGO, XBT and GLIDER observations.OceanVar software was developed using Fortran90 and it uses the NetCDF...
