WMO Satellite Data Dissemination Strategy
Major objective for
WMO and CGMS
in the coming
decade :
Ensuring
operational
access to and use
of satellite data
and products
for a growing
number of WMO
Members
To achieve this, we are faced
with major challenges and
opportunities:
• exponential growth of data rates
generated by new satellites
• requirement for improved latency, for
example for NWP
• digital divide between most and least
advanced users
• need for integration of satellite data and
products into WIS
• ensuring interoperability and
standardization of evolving systems
• taking advantage of technology
opportunities (e.g. Cloud technology)
• threat to radio frequency allocations for
meteorological satellites

WMO Satellite Data Dissemination Strategy
- Outline of a strategic
framework for satellite data
dissemination presented to
CGMS-42
- Proposing strategic targets
and high-level actions
- Aimed at strengthening
access to satellite data and
products required by
operational users
- Accounting for future
challenges and
opportunities.
WMO-WP-09 @ CGMS-43 UCAR, Boulder, Colorado
- Based on outline, a
medium-term Satellite
Data Dissemination
Strategy has been
formulated by WMO
(Space Programme in
collaboration with WIS),
- For each of the strategic
targets, the status is
presented, and
actions and progress
indicators proposed.

WMO Satellite Data Dissemination Strategy





Main objective: to strengthen the access by WMO members to Satellite
Data and Products
Covers the whole activity chain:

from provision of information to users about satellite data
availability, to

definition of specific user data requirements, to

data access by users.
Provides a high-level view of Satellite Data Dissemination and sets
specific strategic targets
Based on strengthening and focusing existing activities, and not
creating new
The strategy strives to implement the “Vision of Satellite Data and
Products exchanged within the WMO Information System (WIS)”,
formulated by WMO Space Programme

WMO will monitor the implementation of the
different elements of the strategy through
appropriate indicators, and report progress to
CGMS-44
CGMS is invited to


Comment on the medium-term strategy for satellite
data dissemination, as laid out in WMO-WP-09
Support the implementation of the strategy in
contributing to the identified strategic targets, actions
and indicators, as appropriate, and in taking the
proposed strategic targets into account in their own
dissemination plans
