Values for each channel and for the nadir and oblique views occupy separate NetCDF files within the Sentinel-SAFE format, along with associated uncertainty estimates. Additional files contain cloud flags, land and water masks, and confidence flags for each image pixel, as well as instrument and ancillary meteorological information.\r\n\r\nThis A/ATSR product [ENV_AT_1_RBT] in NetCDF format stemming from the 4th AATSR reprocessing, is a continuation of ERS ATSR data and a precursor of Sentinel-3 SLSTR data. It has replaced the former L1B product [_TOA_1P] in Envisat format from the 3rd reprocessing. Users with Envisat-format products are recommended to move to the new Sentinel-SAFE like/NetCDF format products. \r\n\r\nThe 4th reprocessing of ERS-1 ATSR-1 data was completed in 2023.","keywords":"ATSR1, AATSR multimission, Sentinel-SAFE","publicationState":"published","dataPublishedTime":"2025-03-24T11:08:53","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/43623/?format=json","dataPath":"/neodc/aatsr_multimission/atsr1-v4/data/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":17913206554553,"numberOfFiles":50876,"fileFormat":"AT_1_RBT ESA SAFE Format"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12145/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1/?format=json","nonGeographicFlag":false,"phenomena":[],"dataLineage":"The data were acquired by the European Space Agency's (ESA) ERS1 satellite and this fourth reprocessing was completed by ESA and the data copied to the Centre for Environmental Data Analysis (CEDA) where users can access the data.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/7803/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/43182/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/208757/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208758/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208759/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208760/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208761/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208762/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208763/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/208764/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":"https://catalogue.ceda.ac.uk/api/v2/composites/10929/?format=json","procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2586/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"https://sentinel.esa.int/documents/247904/690755/Sentinel_Data_Legal_Notice","licenceClassifications":"any"}],"discoveryKeywords":[]}
