At each location, time series are provided for each available single sensor and then merged in a unique time series.  These multi-mission, multispectral time series are also referred to as CM.  The river discharges are derived following several approaches:\r\n\r\nCalibrated CM approach - best fit regression (cal-BestFit): by non-linear regression relationship between the multi-mission time series and the ground observed river discharge;\r\n\r\nCalibrated CM approach - copula regression (cal-copula): by a bivariate cumulative distribution function which is applied between the multi-mission time series and the ground observed river discharge to get their joint probability distribution;\r\n\r\nUncalibrated CM approach – CDF (uncal_CDF): by Cumulative Distribution Function curves calculated to generate the percentiles associated to the discharges from the reflectance time series.","keywords":"river discharge, CCI, multispectral","publicationState":"citable","dataPublishedTime":"2024-11-28T19:12:27","doiPublishedTime":"2024-11-28T23:02:19","updateFrequency":"","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/43215/?format=json","dataPath":"/neodc/esacci/river_discharge/data/RD/RD-multi/v1.2/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":10756247,"numberOfFiles":103,"fileFormat":"Data are in both CSV and NetCDF format"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/11887/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/529/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/50559/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50561/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/63576/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/75233/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/75234/?format=json"],"dataLineage":"Data were produced by the River Discharge CCI project, and supplied to CEDA for archiving as part of the CCI Open Data Portal.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/13211/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/41537/?format=json"],"observationcollection_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/202099/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202100/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202101/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202102/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202103/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/202104/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/205507/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/205510/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/205511/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/205508/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/205509/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":"https://catalogue.ceda.ac.uk/api/v2/composites/43210/?format=json","procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2612/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"https://artefacts.ceda.ac.uk/licences/specific_licences/esacci_river_discharge_terms_and_conditions.pdf","licenceClassifications":"any"}],"discoveryKeywords":[{"ob_id":1140,"name":"ESACCI"}]}
