Global ocean modelling activities at Centro Euro-Mediterraneo per i Cambiamenti Climatici (CMCC) include the development and implementation of data assimilation techniques applied to a global ocean general circulation model to investigate the role of the ocean on climate variability and predictability. The main objective is the production of global ocean re-analyses over multidecadal periods to reconstruct the state of the ocean and the large scale circulation over the recent past for climate applications and for the assessment of the benefits of assimilating ocean observations on seasonal and longer climate predictability.
Here we present the main characteristics of the assimilation system and a set of global ocean re-analyses produced with this system. Applications of these data assimilation products to the study of climate variability and to the assessment of subsurface ocean initialization contribution to seasonal climate predictability will also be reported.

The authors wish to thank the Centro Euro-Mediterraneo per i Cambiamenti Climatici for its financial and scientific support of some of the activities presented in this work. The implementation and the following improvements of the global ocean assimilation system were carried out in the framework of the ENACT (EVK2-CT2001-00117) and ENSEMBLES (GOCE-CT-2003-505539) projects.
The MyOcean (FP7-SPACE-2007-1) project is feeding some of the most recent developments.
