¾ Finally an efficient data management system able to distribute the
ARGO data in real-time within 24h from acquisition both on GTS
(Global Telecommunication System used by the meteorological
agencies) for meteorological community and in FTP for other
operational users. This system is based on collaborative work
between national data centres that process the data from the float
deployed by their country, or partner countries, and a centralized
data distribution through two Global Data Centres (one in
CORIOLIS/France and one in FNMOC/USA). The architecture of
this data management network will be presented at §5.1.1. Since
2004, the Data Management team is putting into operation the
delayed mode procedures developed by the Science team.
The real challenges are now to secure funds on an operational and
sustained budget to maintain this observing system. It is also to improve the
technology to increase the lifetime of the platforms as well as their ability to
survive in dangerous area such as partially ice covered regions.

SOO / VOS and GOSUD: Surface data
Merchant vessels are doing long ocean transects on regular basis and are
good platforms to implement repetitive measurements. On the other hand,
research vessels frequently traverse the oceans on routes where few other insitu ocean observations are available. As such, they represent a natural and
cost-effective mechanism to deliver routine oceanographic data along their
way. These data include temperature and salinity at the surface as well as
currents. Sea surface salinity (SSS) is an important parameter that is not yet
measured from space.
In 2000, the GOSUD project was set up, under the IOC umbrella, as an
end-to-end system for data collected from ships along their cross-ocean
tracks. The goal of GOSUD is to develop and implement a data system for
ocean surface data, to acquire and manage these data and to provide a
mechanism to integrate with other types of data collected in the world
oceans. It is complementary of the SOOP/ VOS projects that under JCOMM
umbrella that organize the data collection from Voluntary Observing Vessels
or Ships of Opportunity. The project seeks to organize underway-surface
data that are currently collected and to work with data collectors to improve
data collection. These data, complementary to ARGO and OceanSites (see
figure 3), will be one of the major ground truths for the calibration of the
Salinity satellites SMOS and Aquarius.
