The CMCC Global Ocean Physical Reanalysis System (C-GLORS) is used at CMCC to simulate the state of the ocean in the last decades. It consists of a variational data assimilation system (OceanVar), capable of assimilating all in-situ observations along with altimetry data, and a forecast step performed by the ocean model NEMO coupled with the LIM2 sea-ice model.
C-GLORS is currently implemented in a 1/2 degree resolution and a 1/4 degree resolution configurations, both using 50 vertical levels. The former is mainly used for testing purposes, long-term simulations and ensemble simulations, while the latter for the production of reanalyses in the last two or three decades, in the framework of MyOcean and GEMINA projects.
