1 GSCB Workshop 2009: EUMETSAT Missions Dr. Harald Rothfuss, EUMETSAT. GSCB Workshop 2007, ESRIN, Frascati, June Slide: 1

2 Introduction To EUMETSAT The European Organisation for the Exploitation of Meteorological Satellites, EUMETSAT, is an intergovernmental organisation, established in 1986 and is headquartered in Darmstadt, Germany. EUMETSAT is funded by the National Meteorological Services of its Member States to deliver operational satellite data and products that satisfy the meteorological and climate data requirements of the Member States 24 hours a day, 365 days a year, through decades. This is carried out taking into account the recommendations of the World Meteorological Organization (WMO). EUMETSAT s primary objective is to establish, maintain and exploit European systems of operational meteorological satellites. A further objective is to contribute to the operational monitoring of the climate and the detection of global climatic changes. Slide: 2

3 EUMETSAT Missions EUMETSAT operates and processes and disseminates data from: first generation Meteosat geostationary satellites (Meteosat-6, 7), second generation Meteosat geostationary satellites (Meteosat-8, 9), polar-orbiting Metop satellites (Metop-A). Ocean Surface Topography Mission (Jason-2). EUMETSAT also routinely acquires, processes and disseminates data from: NOAA polar-orbiting satellites (NOAA-19). Slide: 3

11 GEONETCast Availability of Data GEONETCast is a contributing element to the emerging Global Earth Observation System of Systems (GEOSS) that is being coordinated by the intergovernmental Group on Earth Observations (GEO). GEONETCast is a global network of satellite based data dissemination systems providing environmental data to a world-wide user community. GEONETCast consists of: EUMETCast: EUMETSAT s contribution. FengYunCast: The China Meteorological Administration s contribution, utilising the AsiaSat4 satellite to broadcast data and products to a user community in the Asia-Pacific region. GEONETCast-Americas: A future broadcast system covering the Americas, which is currently being planned by NOAA. Slide: 11

13 EUMETSAT Data Policy EUMETSAT is the owner of its satellites plus the data and products generated from the satellites and the EUMETSAT ground segment. National Meteorological Services (NMSs) of EUMETSAT Member States receive all EUMETSAT data for Official Duty use at no cost. NMSs of EUMETSAT Member States act as Exclusive Licensing Agents of EUMETSAT for users within their national territories, and apply the uniform EUMETSAT fees and conditions. EUMETSAT Secretariat acts as licensing authority for users outside of EUMETSAT Member States and for international organisations. EUMETSAT Secretariat is also licensing authority for archived data and for derived products generated by the EUMETSAT ground segment. Slide: 13

14 EUMETSAT Data Policy (cont) A set of data is declared as Essential, as defined by WMO, and provided free of charge to all users, world-wide (e.g. 6-hourly image data, all data from Metop local mission). A further set of data is provided to NMSs of non-member States free of charge for Official Duty use (e.g. 3-hourly image data). Free of charge access to all data is given for scientific and educational use (including amateur use). Other types of users have to pay a fee, which varies depending on user category (i.e. End Users, Service Providers or Broadcasters). Commercial activities of NMSs of Member States are treated like Service Providers. Slide: 14

15 Long-Term Data Preservation Legacy data from all Meteosat satellites back to Meteosat-2 launch in 1981 migrated into U- MARF. New EUMETSAT programmes fund the transcription of previous programme archives so that they inherit the existing archive, thus ensuring long-term data preservation. Data and products from on-going missions archived routinely. Current monthly ingestion: ca. 9 TB Current monthly retrieval: ca. 50 TB Currently registered users: ca Multiple copies of all archived data maintained second copy stored off-site (Offenbach), with third copy on disk for most demanded products. Periodic migration of data onto new media (from experience, approximately every 5 years). U-MARF catalogue data and products versioning ensures support to reprocessing. Slide: 15

19 Standardisation Assessment HMA: Interoperability of EO-Archives is of fundamental importance in facilitating integrated data access for environmental analysis, e.g. in GMES context. EUMETSAT is implementing the HMA services (as per previous slides). They are enabled following successful establishment of bilateral agreements (like the one already existing with CNES) LTDP: As one of Europe s leading operational Satellite Data Provider, EUMETSAT has long experience in data preservation. The policy in house is coherent with the LTDP guidelines. Climate studies can benefit from geostationary METEOSAT image data in the Archive dating back until QA4EO: EUMETSAT is a partner in the Global Space-based Inter-Calibration System, an initiative from WMO and CGMS to derive homogeneous, well calibrated data from the international constellation of operational meteorological satellites. Guidelines of the QA4EO will be taken into account. Slide: 19
