Observation Instance
Get a list of Observation objects.
### Available end points:
- `/observations/` - Will list all Results in the database
- `/observations.json` - Will return all Results in json format. This can
also be achieved by using the accept header. `application/json`
- `/observations/<object_id>/` - Returns Results object with that id
### Available Methods:
- `GET`
- `HEAD`
### Available filters:
- `title`
- `uuid`
- `keywords`
- `status`
- `result_field`
- `discoveryKeywords`
- `updateFrequency`
- `nonGeographicFlag`
- `publicationState`
- `permissions`
### How to use filters:
These filters can be used like django query filters using __ for related model relationships.
- `/observations/?uuid=d594d53df2612bbd89c2e0e770b5c1a0`
- `/observations/?status=completed`
- `/observations/?results_field__dataPath__startswith=/neodc/esacci`
- `/observations/?discoveryKeywords__name=ESACCI`
- `/observations/?nonGeographicFlag=True`
Filters can be stacked to build an 'AND' relationship. E.g.
- `/observations/?publicationState__in=published,citable&nonGeographicFlag=True`
- `/observations/?publicationState__in=published,citable&discoveryKeyword__name=NDGO0003`

Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. Data generation and distribution of this V4.20 product ended on July 1, 2020 to support a change in the operating system of the CALIPSO production clusters. The V4.21 data product covers July 1, 2020 to current. \r\n\r\nCALIPSO was launched on April 28, 2006, to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite comprises three instruments, CALIOP, Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES (Centre National D’Etudes Spatiales).", "keywords": "NASA, CALIPSO, CALIOP, Cloud, Aerosol", "publicationState": "working", "dataPublishedTime": null, "doiPublishedTime": null, "updateFrequency": "", "status": "ongoing", "result_field": { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/40100/?format=api", "dataPath": "/neodc/caliop/data/l2_vfm/v4-20", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 3311943523102, "numberOfFiles": 72020, "fileFormat": "Data are HDF4 formatted" }, "timePeriod": "https://api.catalogue.ceda.ac.uk/api/v2/times/11101/?format=api", "geographicExtent": "https://api.catalogue.ceda.ac.uk/api/v2/bboxes/1/?format=api", "nonGeographicFlag": false, "phenomena": [ "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64153/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64154/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64155/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64156/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64157/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64158/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64159/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64160/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64161/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64162/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64163/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64164/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64165/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64166/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64167/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64168/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/64169/?format=api" ], "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://api.catalogue.ceda.ac.uk/api/v2/projects/8349/?format=api" ], "observationcollection_set": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195376/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195377/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195378/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195379/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195380/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195381/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195382/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195383/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/195384/?format=api" ], "procedureAcquisition": null, "procedureCompositeProcess": "https://api.catalogue.ceda.ac.uk/api/v2/composites/8391/?format=api", "procedureComputation": null, "permissions": [ { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/2559/?format=api", "useLimitation": null, "accessConstraints": null, "accessCategory": "registered", "accessRoles": null, "label": "registered: None group", "licenceURL": "https://eosweb.larc.nasa.gov/citing-asdc-data", "licenceClassifications": "any" } ], "discoveryKeywords": [] }
