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 cabin is set in approximately 2 acres of grassland with established trees to the North and East, ca 10 km south of Edinburgh (55.862281,-3.205782). The cabin was installed in the 1980s for the then Institute of Terrestrial Ecology (now UK Centre for Ecology and Hydrology), with a basic measurements of total global solar radiation, rainfall, air temperature, wind direction and wind speed at ca 4 m. Initially these were not electronically recorded but in 1988 a Campbell Scientfic data logger was added to allow the automatic reading and recording of the data. Various other sensors were added over the years with the logging system being upgraded as the technology developed. In the early 2000's a taller mast was installed with the sensors at ca 8 m to reduce the influence of the mature trees surrounding the field. The site is been part of national monitoring networks, https://uk-air.defra.gov.uk/interactive-map", "keywords": "Bush Cabin, CEH", "publicationState": "published", "dataPublishedTime": "2026-08-10T14:10:37", "doiPublishedTime": null, "updateFrequency": "", "status": "ongoing", "result_field": { "ob_id": "https://catalogue.ceda.ac.uk/api/v2/observations/46041/?format=api", "dataPath": "/badc/auchencorth/data/BushCabin_1988_2024_met/", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 87464094, "numberOfFiles": 40, "fileFormat": "BADC-CSV" }, "timePeriod": "https://catalogue.ceda.ac.uk/api/v2/times/13233/?format=api", "geographicExtent": "https://catalogue.ceda.ac.uk/api/v2/bboxes/5170/?format=api", "nonGeographicFlag": false, "phenomena": [], "dataLineage": "Data were produced by the project team and supplied for archiving at the Centre for Environmental Data Analysis (CEDA).", "removedDataTime": null, "removedDataReason": "", "language": "English", "identifier_set": [], "projects": [ "https://catalogue.ceda.ac.uk/api/v2/projects/25088/?format=api" ], "observationcollection_set": [ "https://catalogue.ceda.ac.uk/api/v2/observationcollections/25087/?format=api" ], "responsiblepartyinfo_set": [ "https://catalogue.ceda.ac.uk/api/v2/rpis/220074/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220075/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220076/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220077/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220078/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220079/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220080/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220081/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220082/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220083/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220084/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220085/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220086/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220087/?format=api", "https://catalogue.ceda.ac.uk/api/v2/rpis/220088/?format=api" ], "procedureAcquisition": "https://catalogue.ceda.ac.uk/api/v2/acquisitions/46042/?format=api", "procedureCompositeProcess": null, "procedureComputation": null, "permissions": [ { "ob_id": "https://catalogue.ceda.ac.uk/api/v2/observations/2526/?format=api", "useLimitation": null, "accessConstraints": null, "accessCategory": "public", "accessRoles": null, "label": "public: None group", "licenceURL": "http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/", "licenceClassifications": "any, attribution required" } ], "discoveryKeywords": [] }
