Abstract

The WMO Space Programme was established by the Fourteenth WMO Congress in May 2003 and inaugurated on 1 January 2004 as a new major cross-cutting Programme.  The paper describes the current status of the expanded space-based component of the World Weather Watch’s Global Observing System (GOS) including access by WMO Members to new data streams from R\&D space missions.  In particular, the paper focuses on the development of the Integrated Global Data Dissemination Service (IGDDS), a component of the WMO Information System (WIS) that will improve satellite data access by WMO Members.  IGDDS will also be a core component of data dissemination for the Group on Earth Observation (GEO) Global Earth Observation System of Systems (GEOSS).  GEOSS data dissemination for all nine societal benefit areas will be provided through a new system called GEONETCast.

IGDDS defines the satellite data and products circulation scheme that is expected to meet the needs of WMO Programmes, within the WMO Information System (WIS), in accordance with the WMO Space Programme Implementation Plan 2004-2007 agreed by the WMO Executive Council at it fifty-sixth session (EC LVI, 2004).  IGDDS was endorsed by WMO EC LVI in order to ensure that Advanced Dissemination Methods (ADM) initiatives resulted in a dissemination system that was optimized with respect to the needs of the global user community.  It was appropriate to consider the possible shape of IGDDS which would build on the ADM concept.  The concept of IGDDS is also seen as central to the vision of an integrated space-based component of the Global Observing System as it will facilitate the access to the complete range of data and products from this component of the WMO’s GOS.

Furthermore, the necessary articulation between IGDDS and the WMO Information System was addressed at WMO Executive Council’s fifty-seventh session (EC LVII, 2005) that emphasized the important role of satellite-based data-distribution systems and noted their extensive implementation and the significant technological upgrades (e.g., DVB-S) that had been achieved.
