Description:
Global ocean modelling activities at Centro Euro-Me
diterraneo per i Cambiamenti Climatici
(CMCC) include the development and
implementation of data assimilation techniques appl
ied to a global ocean general circulation model to
investigate the role of the
ocean on climate variability and predictability. T
he main objective is the production of global ocean
re-analyses over multidecadal
periods to reconstruct the state of the ocean and t
he large scale circulation over the recent past for
climate applications and for
the assessment of the benefits of assimilating ocea
n observations on seasonal and longer climate predi
ctability.
Here we present the main characteristics of the ass
imilation system and a set of global ocean re-analy
ses produced with this
system. Applications of these data assimilation pro
ducts to the study of climate variability and to th
e assessment of subsurface
ocean initialization contribution to seasonal clima
te predictability will also be reported.

The authors wish to thank the Centro Euro-Mediterra
neo per i Cambiamenti Climatici for its financial a
nd scientific support of
some of the activities presented in this work. The
implementation and the following improvements of th
e global ocean assimilation
system were carried out in the framework of the ENA
CT (EVK2-CT2001-00117) and ENSEMBLES (GOCE-CT-2003-
505539)
projects. We wish to thank Dr. A. Bellucci for his
effort in this activity during the ENACT project. W
e are grateful to the TAO Project
Office for the TAO data, and James Carton and Genna
dy Chepurin for supplying salinity data from Bermud
a station. The
MyOcean (FP7-SPACE-2007-1) project is feeding some
of the most recent developments.
