The horizontal velocity is provided in true meters per day, towards the EASTING(x) and NORTHING(y) directions of the grid; the vertical displacement (z), derived from a digital elevation model, is also provided. Please note that previous versions of this product provided the horizontal velocities as true East and North velocities.","keywords":"Greenland, Ice sheet, CCI, ESA","publicationState":"published","dataPublishedTime":"2016-11-30T15:25:21","doiPublishedTime":null,"updateFrequency":"","status":"superseded","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/20111/?format=json","dataPath":"/neodc/esacci/ice_sheets_greenland/data/greenland_ice_velocity/greenland_ice_velocity_map_winter_2015_2016/v1.0","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":363850037,"numberOfFiles":8,"fileFormat":"Data are in NetCDF and GeoTiff format"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/5272/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1650/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/12066/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13204/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13205/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13206/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/13207/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50547/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50548/?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/75510/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/75511/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/76446/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/76445/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/104942/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105159/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/105337/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/76444/?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"}]}
