    "abstract": "Meteosat-7 and its predecessors were the first generation of earth observation dedicated geostationary satellites located at 36000 km above the intersection of the Equator and the Greenwich Meridian. Although superseded by MSG-1 (renamed Meteosat-8) in 2005, Meteosat-7 remained as back-up at 0o longitude until 14th June 2006. Meteosat-7 will be moved to 63oE longitude to continue coverage of the Indian Ocean and take over from Meteosat-5.\r\n\r\nMeteosat-7 was launched by the European Space Agency and operated by Eumetsat.\r\n\r\nThis dataset collection contains visible, water vapour, thermal and infra-red images of the North Atlantic Ocean, Europe and North Africa from the Meteosat geostationary satellite. Images are archived from 11th November 1999 to June 2006. These images are public.\r\n\r\nData were collected every half hour in three wavelength channels for visible, infra-red and water vapour images.",
