• GMES & Africa and Copernicus Marine Earth Observation

    This is the online phase for the GMES&Africa and Copernicus Marine Earth Observation Training Course. 

    This training is co-organised by the MarCoSouth GMES&Africa consortia and EUMETSAT in collaboration with other GMES&Africa partners and guest lecturers.

    The MarCOSouth project aims to maintain, further develop and provide a sustainable platform for local, institutional, human and technical capabilities in the African countries  through the development of services focused on sustainable socio-economic development, empowering a wide range of users in the public and private sectors through the application of regionally-optimised satellite observations and model based forecasts in African marine and coastal domains.

    Through Global Monitoring for Environment and Security (GMES) and Africa, the Africa Marine and Coastal Operations projects will contribute to the implementation of the African Space Policy and Strategy (ASPS) through application of world-leading satellite sensors, e.g. the European Sentinel series, with innovative and regionally optimised products. Examples of ASPS objectives addressed are: developing indigenous infrastructure and capabilities that service an African market; provisioning regionally appropriate services and products; ensuring all levels of government are able to access data through a centralised portal.

    The goal of this workshop is to strengthen your capacities to develop Earth Observation products, services and tools that promote sustainable management of marine resources, improve marine governance, and stimulate the growth of the blue economy in Africa..The online phase will introduce you to the Copernicus Marine Data Stream (CMDS), providing you with the background knowledge of the Copernicus programme, satellites and instrumentation, data access and formats, tools and software, necessary to begin working with this data for marine applications .The aims of this training course (both the online and classroom phases) are to help you:

    • Understand the concepts around Earth Observation across the value chain;
    • Learn the underlying principals of marine remote sensing, how to access / download data and products, and how to work with various open source tools; 
    • Develop and deliver a 'mini project' so you are able to gain all the skills that are directly applicable to your research / work needs.
    This online phase will be followed by a classroom phase in Zanzibar, Tanzania from the 12th - 20th November (applications are closed).


  • Sentinel-3: Accessing the data

    Within this topic we will introduce you to several ways you can access the Sentinel-3 data available through the EUMETSAT Copernicus Marine Data Stream (CMDS). Which method you choose will depend on a number of factors including:

    • The type of data you need (quick look images, netcdf files, what resolution and at what level of timeliness)
    • How regularly you need this data (for an individual application, or more regularly?)
    • The facilities you have available (do you have sufficient internet capacity to download the data?)



    Get a quick look at recent coverage from the Sentinel 3 instruments, download image files, and make animations.




    Download service offers all the recently acquired Sentinel-3 marine and atmospheric products through a rolling dataset that (at a maximum) spans 12 months.
