The main objective of the mission was to supply a unique data set of vertical cloud and aerosol profiles.\r\n\r\nThis dataset contains cloud and aerosol lidar level 2 vertical feature mask version 4-51 data product describes the horizontal and vertical distribution of the cloud and the aerosol layers observed by the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). CAL_LID_L2_VFM-Standard-V4-51 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 2 Vertical Feature Mask (VFM), Version 4-51 data product. Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. The version of this product was changed from 4-20 to 4-21 to account for a change in the operating system of the CALIPSO production cluster.","keywords":"NASA, CALIPSO, CALIOP, Cloud, Aerosol","publicationState":"published","dataPublishedTime":"2025-04-16T10:57:28","doiPublishedTime":null,"updateFrequency":"","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/43953/?format=json","dataPath":"/neodc/caliop/data/l2_vfm/v4-51","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":7431238114943,"numberOfFiles":161825,"fileFormat":"Data are HDF4 formatted"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12281/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/1/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/64153/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/64154/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/64155/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/64159/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/64163/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/64167/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/65048/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85626/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85629/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85639/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85658/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85668/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85999/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/86000/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/86001/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/86002/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/86003/?format=json"],"dataLineage":"These data were obtained from the NASA Langley Research Center Atmospheric Science Data Center and mirrored by CEDA.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/8349/?format=json"],"observationcollection_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/210078/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210071/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210076/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210072/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210077/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210073/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210074/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210075/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210079/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":"https://catalogue.ceda.ac.uk/api/v2/composites/43964/?format=json","procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2559/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"registered","accessRoles":null,"label":"registered: None group","licenceURL":"https://eosweb.larc.nasa.gov/citing-asdc-data","licenceClassifications":"any"}],"discoveryKeywords":[]}
