The data is supplied on a 500m polar stereographic grid. The ice velocity product contain the horizontal components, vN and vE, of the total velocity vector, which is derived from radar measurements assuming surface parallel flow. The used digital elevation model of the surface is also supplied. The North and East velocities at any grid points are given in a local geographic north-east coordinates system (and not in the used grid map projection system).","keywords":"Greenland Ice Sheet, ESA, CCI","publicationState":"published","dataPublishedTime":"2016-04-11T16:10:49","doiPublishedTime":null,"updateFrequency":"","status":"superseded","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/14324/?format=json","dataPath":"/neodc/esacci/ice_sheets_greenland/data/greenland_ice_velocity/old_products/Greenland_Northern_Drainage_Basins_ERS1_Winter_1991_1992/v1.1","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":136485023,"numberOfFiles":7,"fileFormat":"Data are NetCDF-4 formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/3788/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/895/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/12066/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13230/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13231/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13232/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13233/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50547/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50548/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/53928/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/63972/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/79994/?format=json"],"dataLineage":"Data were processed by the ESA CCI Greenland Ice Sheet project team and supplied to CEDA in the context of the ESA CCI Open Data Portal Project.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/14317/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/14316/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/55340/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55341/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55342/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55611/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/104876/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105090/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105269/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/55343/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2553/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"https://artefacts.ceda.ac.uk/licences/specific_licences/esacci_icesheets_greenland_terms_and_conditions.pdf","licenceClassifications":"any"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
