The\r\nmethod involves separating the radar echoes returning from the ice floes from those\r\nreturning from the sea surface in the leads between the floes. This step of a surface-type\r\nclassification is crucial and allows for a separate determination of the ice floe and\r\nsea-surface heights. The freeboard that is the elevation of the ice upper side (or ice/snow\r\ninterface) above the sea level can then be computed by deducting the interpolated\r\nsea-surface height at the floe location from the height of the floe. Sea-ice thickness can then\r\nbe calculated from the sea-ice freeboard with the additional information of the snow load.","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}],"acquisitionComponent":[{"ob_id":26734,"independentInstrument":[],"instrumentplatformpair_set":[{"ob_id":11941,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/26733/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/26732/?format=json","relatedTo":{"ob_id":26734,"uuid":"eda0664efbab45bf82345cd5d257d7df","short_code":"acq"}}]}],"identifier_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/201788/?format=json"]}
