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 5

6 Country specific findings and challenges Kenya (Mr. Gitonga) WMO 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 6

7 Country specific findings and challenges Mauritius (Mr. Dhurmea Ram Kumar) WMO 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 7

8 Country specific findings and challenges Cameroun (Mr. BONGKIYUNG Emmanuel NYUYKI) WMO 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 8

9 Country specific findings and challenges Ethiopia (Mr. Kassa Fekadu) WMO 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 9

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 10

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: Point of contact Product identifier Providing organization Data source Applicability domain Geographical region Resolution Update frequency Access information Quality indication / documentation With the aim to satisfy users` needs for documentation and to harmonized online product metadata used by providers 14

15 (1) Product Access Guide (PAG) PAG Link: 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 15

16 (1) Product Access Guide (PAG) Current status Links to 86 product collections from several providers: Sounder Radiances, Inland Waters (Rivers, Lakes Floods), Soil Moisture, Clouds, Land Cover, Fire, Volcanic Ash, Aerosols, Dust, Lightning, Sea Level, Ocean Colour, Winds, Land Surface Temperature, Precipitation, Vegetation NDVI, Ocean Surface Winds, Ozone, Green House Gases and other trace gases, Ionosphere, Sea Surface Temperature, Ocean Surface Winds,.. This now includes links to relevant sub-sets of the EUMETSAT Product Navigator 23 links to sets of corresponding online training materials 14 links to international expert groups (e.g., on precipitation, winds) Quick Demo: 16

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 17
