RAIDEG7 and GFCS needs Mariane Diop Kane Chair of RAIDEG Director of Meteorology, ANACIM
RA-I Dissemination Expert Group (RAIDEG) Established in 2010 by WMO, in cooperation with EUMETSAT Endorsed by WMO RA-I at its 16 th session in 2015, as part of its Working Group on Observations Telecommunications and Infrastructures Its overall role is: to improve satellite data accessibility and user awareness in RA-I. Its purpose is: to optimise data and products dissemination trough EUMETCAST and usage by the African community
RA-I Dissemination Expert Group (RAIDEG) The Expert Group is composed of experts from the:- National Meteorological Services; Morocco, for Northern Africa, Senegal, for Western Africa, Congo, for Central Africa, South Africa, for Southern Africa, Mauritius, for Indian Ocean region, and Kenya, for Eastern Africa. Regional Training and Climate Centres (IMTR, SAWS, EAMAC, ACMAD); MESA RIC for oceanic thema (Univ of Ghana) EUMETSAT; and WMO Secretariat.
RAIDEG 7 at EUMETSAT User Forum Kigali, 12-16 September2016
RA-I Dissemination Expert Group (RAIDEG) Activities of the Group include: Feedback on the EUMETCast-Africa baseline Expression of user needs for satellite data, NWP products and software Defining the training needs related to satellite and NWP products User feedback on MESA implementation Invitation to MESA infrastrutures tender evaluation Factory acceptance tests Expression of marine products needs and service requirements Side meeting for AU-AMCOMET Space program during the forum: RAIDEG can be a building block in developing the elements of the meteorological input for the Implementation Plan of the African Space Programme User representation in preparation for Meteosat Third Generation (MTG) MTG for Africa Project Study; lots of discussion for the optimum data to send in Africa bearing in mind the bandwidth limit
What does MTG? A better spectral resolution: 16 channels, with 4 more visible than MSG A better spatial resolution (IR 2km, Vis 1km) with a total coverage of Africa A better spatial resolution (every 10min) A better radiometric resolution (12bits/pixel) A lightning imager An IR sounder A UVN sounder
But at which costs? 10 times more data than MSG Infrastructures to cope with this expansion: MORE Bandwidth to transmit the data adequate equipments to receive the data, analyse and visualise WE NEED TO PRIORITISE TO GET BEST OF IT
Several consultations with EUMETSAT Questionnaire on products usedfor atmosphere, cloud, convection, aerosol/visibility, environment and agricultural services, marine and their frequency Questionnaire on lightning products Survey of the instutions profile Questionnaire on the RGBs we use and their applications Followed by a MAPS workshop during 2015 RAIDEG meeting
Leading to 2 proposed scenarii both starting with actual MSG dissemination but every 20min, then lighting A: SAF L2 products, then add MTG channels progressively every 10min, fire, then AMV, cloud and radiance products B: SAF L2 products, then add MTG every 20min, then, fire, etc
analysis of choices unconclusive Need a scenario balancing both temporal resolution and spatial resolution work out optimal solutions

Proposed transition scenarios A. One step: one bang: MTG replaces immediately MSG B. 2 steps: transition period both MSG and MTG, then gradually MTG replaces MTG C. 3 steps too complicated
Recommandations of RAIDEG7 1. PRs: Nominate focal points to better address the African community needs 2. MESA RICs: to work with RAIDEG for their needs 3. Eumetsat: To continue investigations optimising both temporal and spatial resolutions 4. Noting the bandwith limitations, appreciating the efforts of EUMETSAT to garanty continuity of optimum service, we recommand the African community to seek extra funding with (for bandwith and infrastrures) in order to make best use of MTG
Outcomes of the joint meeting RAIDEG- CSA WG, Geneva, 18-19 April 2017 Participation of WMO secretariat and EUMETSAT Climate Information from the service-user perspectives have been identified; Focus on GFCS priority areas Energy, Agriculture, Water, DRR, Health. The needs for data, products, infrastructure and tools, as well as capacity gaps at regional scale have been identified Copernicus Climate Change Services (C3S) Climate Data Store (CDS) presented by EUMETSAT. Although still under development, they are creating a User Requirement Data Base for collecting feedbacks from users. So it can be a good mechanism to capture RA-I user requirements and feedback vis-a-vis C3S will be important for data delivery improvement.

Synthesis and actions Some data can be used for several different services, e,g, solar data can be used for: solar energy potential: radiation for crop forecasting in agriculture and for UV monitoring for health Most applications require multiple data sources that need to be worked with in an integrated manner Many climate applications require comparing a climatology with a current observation. This requires a climatology and compatible observation. These may have different dissemination mechanisms(post and EUMETCast). Consistent/ standard tools would be helpful. There is a wide range of data required and a wide range of data available, a rigorous matching exercise or process would be helpful (it does not all need to be done at once). This might/must be an ongoing process, as new requirements and products will come up / will be developed. How services engage with users came up often. NMHSs can do a better job of designing and delivering products that are more useful to users. This is part of the user interface platform in GFCS. There is a systemic requirement for information and training to do this well. Included in this is an element of communicating and working with users. Particularly when the users may act, and the event does not always happen
New data requests for the near term Request to ECMWF to have Extreme Forecast Index (EFI), and training on its use in climate services WMO SDS-WAS data rather than images on EUMETCast 11-30 day data from ECMWF... research data or available operationally? Rainfall T, Humidity,... Monthly satellite products, soil moisture, flooded areas, small water bodies particulate matter, biomass, ash from biomass burning, aerosol optical depth near surface, near ground councentration of ozone, SO2, NO2, VOCs, UV index Longer term requests Access to the Copernicus Climate Change Service (C3S); advice from C3S on data selection and training on data application will be useful in the future phases of C3S. This is probably true for all the Copernicus services / data providers. (Request to be made via ACMAD on behalf of RA I) SWFDP products for West Africa. ENACTS extension to other countries is recommended. Data Access ECMWF / EUM web available to people in health / agriculture - all data in one page, with appropriate user control Requirement need to make discovery easier
