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`

The product has been produced using data acquired from the Thermal and Near Infrared Sensor for Carbon Observations (TANSO-FTS) NIR and SWIR spectra, onboard the Japanese Greenhouse gases Observing Satellite (GOSAT), using the OCPR University of Leicester Proxy Retrieval Algorithm. It has been generated as part of the European Space Agency (ESA) Greenhouse Gases Climate Change Initiative (GHG_cci). This version of the data is v7.0 and forms part of the Climate Research Data Package 4.\r\n\r\nThis algorithm has been designated the baseline algorithm for the GHG CCI proxy methane retrievals. A second product has also been generated from the TANSO-FTS data using an alternative algorithm, the RemoTeC Proxy algorithm. It is advised that users who aren't sure whether to use the baseline or alternative product use this product generated with the OCPR baseline algorithm. For more information regarding the differences between baseline and alternative algorithms please see the GHG-CCI data products webpage.\r\n\r\nThe product is stored in NetCDF format with all GOSAT soundings on a single day stored in one file. For further details on the product, including the UoL-PR algorithm and the TANSO-FTS instrument, please see the associated product user guide (PUG) or the Algorithm Theoretical Basis Documents.", "keywords": "ESA, GHG, CCI, CH4, Proxy", "publicationState": "published", "dataPublishedTime": "2018-03-19T21:23:20", "doiPublishedTime": null, "updateFrequency": "", "status": "completed", "result_field": { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/25929/?format=api", "dataPath": "/neodc/esacci/ghg/data/crdp_4/GOSAT/CH4_GOS_OCPR/v7.0/", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 4746545381, "numberOfFiles": 2396, "fileFormat": "Data are in NetCDF format" }, "timePeriod": "https://api.catalogue.ceda.ac.uk/api/v2/times/7004/?format=api", "geographicExtent": "https://api.catalogue.ceda.ac.uk/api/v2/bboxes/529/?format=api", "nonGeographicFlag": false, "phenomena": [ "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/1050/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/1635/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/1636/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11816/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11852/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11856/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11857/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11858/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11859/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11860/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11863/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11864/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11866/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/11869/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12270/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12271/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12272/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12273/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12274/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12276/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12277/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/12278/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/13276/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/13775/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/13776/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/13777/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/25159/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/25160/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/25161/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/26284/?format=api" ], "dataLineage": "Data were processed by the ESA CCI GHG project team and supplied to CEDA as part of the ESA CCI Open Data Portal Project", "removedDataTime": null, "removedDataReason": "", "language": "English", "identifier_set": [], "projects": [ "https://api.catalogue.ceda.ac.uk/api/v2/projects/13295/?format=api" ], "observationcollection_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/12808/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/30128/?format=api" ], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108385/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108379/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108380/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108384/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108383/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108382/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108381/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108378/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/108386/?format=api" ], "procedureAcquisition": null, "procedureCompositeProcess": null, "procedureComputation": null, "permissions": [ { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/2564/?format=api", "useLimitation": null, "accessConstraints": null, "accessCategory": "public", "accessRoles": null, "label": "public: None group", "licenceURL": "https://artefacts.ceda.ac.uk/licences/specific_licences/esacci_ghg_terms_and_conditions.pdf", "licenceClassifications": "any" } ], "discoveryKeywords": [ { "ob_id": 1138, "name": "NDGO0003" }, { "ob_id": 1140, "name": "ESACCI" } ] }
