3. Introduction
A key objective of the WMO Space Programme is to:
Promote availability and utilization of satellite data
and products for weather, climate, water and related
applications to its Members
In light of this, WMO conducted a user survey in 2012:
Results were presented at RAIDEG-4

5. Follow-up
This work is aimed at following up on the 2012
WMO Survey responses for four African countries
in the areas of:
1. Access to satellite data and products
2. Application and use of satellite data
3. Training on satellite data utilization
This is to better understand their responses and
challenges
NMHS contacted are: Kenya, Ethiopia, Mauritius
and Cameroun

6. WMO
Country specific findings and challenges
Kenya (Mr. Gitonga)
Challenges
Knowledge of the available satellite data/products.
Direct read-out (HRPT) station currently not working.
Preparation for new generation satellites.
Findings
Confirm that HRPT Station is non-functional and both the tracking
unit and the antenna are obsolete
GIS implementation needed to provide local decentralized services
GIS Remote Sensing proposal done but lack funding
Training on quantitative rainfall estimates needed; Classroom
based training favoured

7. WMO
Country specific findings and challenges
Mauritius (Mr. Dhurmea Ram Kumar)
Challenges
Mauritius is on the periphery for the FOV of MSG at 0 degree
Preparation for new generation satellites
Product (Utilization and Interpretation)
Findings
Using products from Meteosat 7 (IODC); INSAT- 3D data are not
available; and relatively poor products from FY-2D
Need more training on monitoring convective activity in a marine
environment; this includes training on scatterometry, images
interpretation (RGB products are critical), manipulating of raw data
to derive products.
EUMETSAT and COMET provide well tailored training materials
Tried out SATURN website and found it to be good and more
information need to be provided

8. WMO
Country specific findings and challenges
Cameroun (Mr. BONGKIYUNG Emmanuel NYUYKI)
Challenges
Knowledge of the available satellite data/products.
Preparation for the new generation satellites.
Use of software tools (processing, analysis, assimilation).
Further training on image interpretation and data processing.
Findings
Further training on GIS for mapping of specific zones, utilization of
marine products and models
Training on quantitative rainfall estimate, damage estimate from
convective systems and use of lightning data

9. WMO
Country specific findings and challenges
Ethiopia (Mr. Kassa Fekadu)
Challenges
knowledge of the available satellite data/products.
equipment operation and maintenance
use of software tools (processing, analysis, assimilation)
Findings
EUMETSAT conducted training courses through CoEs on
availability of data and products
Suggested that Meteo France International provide training on
image analysis, equipment operation and maintenance (use of
SYNERGIE)
EUMETSAT has been working with sub Sahara African countries
to address these challenges for years now

10. 10th African User Forum recommendations
Recommendation #3: Improving user awareness of
satellite data and products
Data providers take further steps to communicate the existing
satellite products.
Recommendation #9: user preparation for new satellite
generations
EUMETSAT takes into account the african user community in its
planning to prepare users for the meteosat third generation
and for the EPS second generation programmes

11. Addressing challenges
Part of the objectives of the WMO 2012 Survey was to
identify areas for improvement and remedial action
Assistance is provided through:
1. WMO Online Resources (OSCAR, PAG, SATURN)
2. WMO-CGMS VLab, EUMETSAT and COMET training activities and
resources in support of RA I
3. CGMS-42 recommendations and actions (re Indian Ocean Data
Coverage)
The next slides explain briefly the WMO online resources and
how they are used to respond to the stated challenges
11
12. (1) Product Access Guide (PAG)
Goal & Objectives
• Web-based WMO resource
• In support of the WMO Information System
• Developed to address insufficient user awareness of
satellite products (WMO Survey, 2012)
• Facilitates access to quality controlled satellite data and
products
• Developed to enhance visibility of satellite products and
related information
• Providers of satellite data retain full ownership and
responsibility for their products
12
13. (1) Product Access Guide (PAG)
Implementation
• Links to stable URLs of satellite product collections,
expert groups, training material
• Products must be sufficiently described to meet user
demand for information (metadata criteria)
• Structured by geophysical domain, tags
13
14. (1) Product Access Guide (PAG)
Acceptance into PAG is based on the following Metadata
Criteria:
With the aim to satisfy users` needs for documentation
and to harmonized online product metadata used by
providers
14
Point of contact Applicability domain
Product identifier Geographical region
Providing organization Resolution
Data source Update frequency
Access information Quality indication /
documentation
15. (1) Product Access Guide (PAG)
1. Hierarchical/Simple Search: select by clicking on the domain
2. Advanced Search: based on combination of tags:Domain, theme, geographic
regional, organization providing and type of content.
3. Highlighted themes: based on themes such as Tropical meteorology, water,
health, disaster

17. (2) OSCAR
What it is?
Observing Systems Capability Analysis and Review Tool(OSCAR)
Web-based inventory and analysis tool
One-stop portal on satellites, instruments, ground-segments
OSCAR currently contains:
Technical details on satellite programmes, mission and instruments as
provided by agencies
> 600 earth observation satellites and
> 800 instruments with detailed characteristics
A tentative evaluation of relevant categories of instruments for
measuring physical variables
Assessment also generates preliminary gaps analysis of these
variables
Assessment on how well actual and planned missions can respond to
WMO Vision of the Global Observing System

22. CGMS-42 : Considerations
CGMS-42 WGIII actions: Indian Ocean Data Coverage (IODC)
A42.01: WMO to dialogue with Indian Ocean satellite operators and clarify
which data are essential in the sense of Resolution 40, in view of the
meteorological requirements in the region.
A42.08: ISRO and EUMETSAT to report at CGMS-43 on their discussions on
data dissemination collaboration for SCATSAT data.
A42.03 : WMO to consider sending a request to CMA for moving an FY-2
spacecraft over the Indian Ocean after successful launch and commissioning
of FY-2G.
A42.02 : EUMETSAT and ISRO will address the technical issues to
accommodate high-resolution half-hourly data from INSAT-3D on
dissemination means.

23. (3) SATURN - General motivation and objective
SATellite User Readiness Navigator Portal (SATURN)
The 2015-2020 generation of meteorological satellites provides:
unprecedented capabilities for key meteorological applications
such as nowcasting, as well as challenges for both satellite
operators and users:
Higher sampling rate, higher spatial resolution, more spectral channels
Expected to lead to more accurate and timely forecasts, and improved
application support
Data rates increase drastically, by factors of 10-100
CGMS and WMO Space Programme developed SATURN to allow
Members exploit the potential operational and socio-economic
benefits of using next-generation satellites
Provides information on new generation of (initially) geostationary
meteorological satellites:
Himawari-8 (JMA), FY-4 (CMA), GOES-R (NOAA),GEO-KOMPSAT-2 (KMA),
Elektro-L N2 (ROSHYDROMET), MTG (EUMETSAT)

26. WMO
Follow up on GIS
Share GIS experience amongst NMHS in Africa
New software introduction considerations
Planning and project approach very important
Following the 5 phases for software introduction which includes:
Preliminary, software requirement, preparation, implementation
and consolidation phases.
Each stage includes the exits strategy and best practices to
increase probability of success
Change management and human factor are very important
Best way to choose a new software
