This data set is part of the ESA Greenland Ice sheet CCI project. \r\n\r\nIt provides the following CSV files: \r\n- Mass flow rate ice discharge. Units are Gt yr^{-1}.\r\n- Mass flow rate ice discharge uncertainty. Units are Gt yr^{-1}.\r\n- Coverage for each sector at each timestamp. Unitless [0 to 1].\r\n\r\nIce discharge is calculated from the CCI Ice Velocity (IV) product, the CCI Surface Elevation Change (SEC) product (where it overlaps with the ice discharge gates), and ice thickness from BedMachine. Ice discharge gates are placed 10 km upstream from all marine terminating glacier termini that have baseline velocities of more than 150 m/yr. Results are summed by Zwally et al. (2012) sectors.\r\n\r\nThe methods, including description of \"coverage\", are described in Mankoff et al. 2020.","keywords":"Greenland, Ice sheet, CCI, ESA","publicationState":"published","dataPublishedTime":"2024-07-08T15:38:25","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/43051/?format=json","dataPath":"/neodc/esacci/ice_sheets_greenland/data/greenland_mass_flow_rate_ice_discharge/v1.0","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":384604,"numberOfFiles":8,"fileFormat":"csv, txt, png"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/7282/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1650/?format=json","nonGeographicFlag":false,"phenomena":[],"dataLineage":"Ice discharge is calculated from the CCI Ice Velocity (IV) product, the CCI Surface Elevation Change (SEC) product (where it overlaps with the ice discharge gates), and ice thickness from BedMachine.
