HALO Logic of Technical Study
Bring together the expertise:
ECMWF (GEMS and coordination) Infoterra GmbH (GEOLAND) Ifremer (MERSEA) Alcatel (Industrial Expertise) Astrium (Industrial Expertise)
Iterate between the partners:
IPs describe monitoring systems and data transfer requirements Industrial partners analyse existing infrastructure and propose
candidate solutions for the data transfer infrastructure IPs evaluate candidate solutions

WMO Information System (WIS)brings new features and
opportunities Interoperable information exchange standards, functions
and services through Portal architecture allowing a variety of codes, protocols, and data representation forms
Inter-disciplinary discovery, retrieval and exchange of information in real and non-real time through a single entry point in each country
Open to all users for data discovery, to authorized users for data access (according to national data policies)
Data are described in on-line catalogues using standardised metadata based on ISO 19139
Industry standards and off-the-shelf hardware and software systems to ensure cost-effectiveness and inter-operability

Overall Recommendations:GMES Information System
GMES will have a diverse user community needing to use products of some or all of the Fast-Track Services and Pilot-Services.
To meet its users’ requirements, GMES must have a modern Information System based on advanced Internet technologies.
GMES has no plan for the creation of such a GMES Information System. There is no call for the development of a GMES Information System in
the December 2006 FP7 call for proposals. The current call explicitly states that each Fast-track service and Pilot-
Service is separately and independently responsible for its own data acquisition and its own product dissemination.
The lack of such a system is a critical gap in GMES planning.
Recommendation 1: As implied by the forthcoming INSPIRE directive(2004/0175 (COD), C-6 0445/2006, PE-CONS 3685/06), GMES leadership should address the provision of a GMES Information System based on Internet technology.
Information Space WS, Frascati, 3 Apr 2007 Kaiser & Hollingsworth, HALO, 25
Overall Recommendations:Infrastructure Candidate Solutions
Several candidate technical mechanisms are available to achieve the required data exchanges between the Core Services of the Integrated Projects, without impeding the development of the scientific interactions between the Projects.
The WMO Information System (WIS) offers several political and technical advantages. The functionality of the WIS meets the requirements of the Atmosphere
and Ocean communities. Interoperability between the WMO and UNESCO / International Ocean
Commission data systems has been demonstrated. (E2EDM project) The functionality of the WIS can meet the needs of the Atmosphere and
Land Communities, provided the necessary work on interoperability is undertaken.
Software development for the European GRID-implementation of the WIS has been funded by the DG/INFO SIMDAT project. The European implementation will be rolled out in 2008.
Information Space WS, Frascati, 3 Apr 2007 Kaiser & Hollingsworth, HALO, 26
Overall Recommendations:Potential Collaboration with WMO
In the course of the HALO project, WMO extended an invitation to GMES to adapt the WIS system to GMES purposes and to share further development of the WIS for joint purposes. This offer of collaboration should be considered seriously because The WIS architecture and implementation has global reach for meteorology and
oceanography. The WIS offers an efficient means for GMES to access WMO’s essential meteorological data The WIS is fully consistent with, and offers all the functionality required by, the forthcoming
INSPIRE Directive in terms of
• Metadata
• Interoperability of spatial datasets and services
• Network services
• Data Sharing The GEOSS system is assessing the suitability of the WIS for GEOSS purposes (Achache,
WMO Bulletin 2006)
Recommendation 2: The GMES leadership should monitor the 2008 roll-out of the WMO Information System in Europe, and assess the adaptability of the WIS for GMES purposes and interoperability with OGC and Earth Science Information Systems.
