{"ob_id":7801,"uuid":"becade1abe4abbd8135bf9b938968cc1","title":"European Remote Sensing Satellite 1 (ERS-1): Synthetic Aperture Radar (SAR) data","abstract":"The European Space Agency's Synthetic Aperture Radar (SAR) instruments have been flown on board ERS-1, ERS-2 and the Advanced SAR (ASAR) on board Envisat. The ERS-1, ERS-2 and Envisat satellites, launched in 1991, 1995 and 2002 respectively, are ESA multi-payload, Earth observation satellites.\r\n\r\nThis dataset contains Synthetic Aperture Radar(SAR) data from the European Remote Sensing satellites ERS-1.  \r\n\r\nThe ERS-1 mission began in 1991 and ended in 2000, and ERS-2 and Envisat are still ongoing.  SAR provides high resolution images, ocean wave spectra data and wind direction vector data.  They are available through the NEODC to UK based students only.","keywords":"ESA, SAR, satellite","publicationState":"published","dataPublishedTime":"2007-08-09T13:45:41","doiPublishedTime":null,"updateFrequency":"unknown","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/7802/?format=json","dataPath":"/neodc/esasar/ers_sar/ER1/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":6140099205,"numberOfFiles":65,"fileFormat":"Data are tar formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/2243/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/22848/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/25947/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/25995/?format=json"],"dataLineage":"Data collected and prepared by ESA before a copy was obtained directly from ESA by NEODC for use by UK student community","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/5062/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/7803/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/7800/?format=json","https://catalogue.ceda.ac.uk/api/v2/observationcollections/30129/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/32287/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32292/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32286/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32289/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32290/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32291/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32293/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/32288/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":"https://catalogue.ceda.ac.uk/api/v2/composites/7809/?format=json","procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2537/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"restricted","accessRoles":"esasar","label":"restricted: esasar group","licenceURL":"https://artefacts.ceda.ac.uk/licences/specific_licences/esasar.pdf","licenceClassifications":"academic, specific"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
