WMO 2012 Survey on the Use of Satellite Data
 Trend in the usage of satellite data
 80 % of respondents state that their overall use of satellite data is increasing,
across all Regional Associations and all application areas
 Many different factors, like demise of in-situ networks, new application areas,
increased quality of satellite products, progress in NWP assimilation or increasing
demand for value-added services that depend on satellite products.
 Access to satellite data
 For 40 % “accessing data in near-real-time” is a challenge
 Strong regional variability: 32 % for RA VI , 65% for RA V users and 72 % to RA III.
 Discovery of satellite data
 39 % stated that “Knowledge of available data” is a challenge
 Regional variability: 31% for RA VI , 46 % for RA I, 50% for RA III and 53% for RA V.
 Resources for exploiting satellite data
 64% stated that “resources (personnel, training, tools etc)” was a challenge
 Strong regional variability: 55% in RA IV, 78% in RA III and 83% in RA V.

IGDDS reformulation
 Evolution of IGDDS concept
 The initial scope of IGDDS was to build a global dissemination service for
satellite data and products based on DVB-S standard
 From a WIS perspective, satellite data and products should however be
handled in an integrated manner with non-satellite data
 Furthermore, Direct Broadcast and terrestrial networks will continue to
play important roles in addition to DVB-S services.
 In conclusion IGDDS has to be seen as addressing the whole circulation
scheme of satellite data & products, in compliance with WIS standards
 Because of this evolution it is necessary to better communicate at the
strategic level while identifying a limited number of focused actions.
 IGDDS is now reformulated as a broad strategy, including

IGDDS vision and strategic targets
 Vision: Timely and reliable access through the WIS to all satellite data
and products needed to meet the operational needs of all WMO
members.
 This vision will be realized through the specific targets:
 Regional and thematic dialogues maintaining data requirements
 Re-broadcast DVB services available in all regions and integrated in WIS
 Globally required satellite data provided to the WIS core network
 Exchange of other satellite data and products between regions
 Global coverage of LEO Direct Readout Acquisition and Relay systems
 Globally coordinated Direct Broadcast from LEO and GEO
 Routine access to required data and products from R&D satellites
 Dissemination providers acting as WIS DCPC, by providing coordinated
data discovery, data access and data retrieval (DAR) for all satellite data
 On-demand access to satellite data and products through the WIS
 Information and guidance to users.

IGDDS strategic activities, status and proposed actions
 Develop data access requirements from broader range of WMO
and co-sponsored programmes
 Status
 APSDEU-NAEDEX are addressing the global data requirements for
NWP
 For other applications data requirements have not been formulated
 JCOMMs new Task-Team for Satellite Data Requirements is expected
to formulate Data Requirements for Ocean Applications
 Actions
 Dialogue should be strengthened with WMO Programmes, JCOMM
and the CGMS/CEOS Climate Group to document evolving
dissemination needs for satellites data
 Results of initiatives like the “Southern Ocean Satellite Data”
requirements survey should also be taken into account.

IGDDS strategic activities, status and proposed actions
 Develop DVB dissemination services, including WIS-integration
 Status
 Considerable progress with EUMETCast, GEONETCast Americas,
JMACast, RapidCast.
 However interoperability and WIS discovery has only been
implemented for EUMETCast and CMACast.
 Actions
 Continue coordination of existing and new DVB-based services.
 Establish (together with WIS) a requirements baseline for the WIS
integration of DVB-S based dissemination services.

exchange
Status
 For current generation of instruments used in NWP
efficient coordinated data formats are in use
 For non-NWP instruments a diversity of product formats
exist, hindering global and regional exchange of data

 Facilitate regional optimization of acquisition and
processing of LEO satellite data
 Status
 The full adaptation of RARS to the high-performance
instruments on NPP/JPSS, METOP and FY-3 is starting, but
commitment from partners is not yet clear.
 Expansion to Africa has started with the support of the EU.
 Actions

IGDDS strategic activities, status and proposed actions
 Maintain and evolve Direct Broadcast standards
 Status
 CGMS DB standards revised for X-band transmissions
from LEO satellites (NPP, JPSS, FY-3, METOP-SG).
 New GEO DB services are however not fully coordinated,
e.g. GOES-R GRB is not based on HRIT/LRIT standard
 Cost to users remains a concern for LEO and GEO
 Actions
 Monitoring of the implementation of the new LEO DB
standard.
 Encourage efforts for reliable, low-cost DB receiving
stations for both LEO and GEO.

IGDDS strategic activities, status and proposed actions
 Develop strategic indicators to support dialogue with decision
makers and other stakeholders
Status
 Original idea of IGDDS was a single project with the perspective
of significantly improving access to satellite data and products.
 The reality in 2014 is complex and only concerted action in a
number of different areas will realize the vision.
Actions
 Develop strategic indicators for the realisation of the IGDDS
vision
 Regular reporting to stakeholders about the status of progress
based on clear strategic indicators

IGDDS oversight and role of CGMS
 IGDDS is a WMO strategy and as such the oversight of the
IGDDS and its implementation is the responsibility of the
relevant WMO Expert Teams, supported by the WMO Space
Programme
 The contribution of CGMS members to the realization of the
IGDDS vision is however crucial
 Therefore CGMS members are invited to comment on the
IGDDS vision and to support the IGDDS strategic activities
 WMO Space Programme will report to CGMS and to other
fora like the Consultative Meeting on Satellite Matters on the
implementation of IGDDS
