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`

This was a year-long project on the German icebreaker Polarstern to study Arctic climate focused on measurements of atmospheric boundary layer dynamics and turbulent structure. The Galion wind profiler provides high resolution (~15m vertical and 5 minute temporal) measurements of wind profiles. Data are only available where sufficient particles are available to backscatter the laser light - in the clean arctic environment, this requires cloud or precipitation.\r\n\r\nThis is version 2 of this dataset.", "keywords": "MOSAiC, NE/S002472/1, AMOF,NCAS", "publicationState": "citable", "dataPublishedTime": "2022-11-18T14:15:41", "doiPublishedTime": "2022-11-18T14:46:43", "updateFrequency": "notPlanned", "status": "completed", "result_field": { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/42818/?format=api", "dataPath": "/badc/ncas-mobile/data/ncas-lidar-wind-profiler-1/20191005_mosaic/v2.0", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 1581135587, "numberOfFiles": 597, "fileFormat": "Data are netCDF formatted." }, "timePeriod": "https://api.catalogue.ceda.ac.uk/api/v2/times/10877/?format=api", "geographicExtent": "https://api.catalogue.ceda.ac.uk/api/v2/bboxes/3419/?format=api", "nonGeographicFlag": false, "phenomena": [ "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/56577/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62763/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62764/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62765/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62766/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62767/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62768/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62769/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62770/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62771/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62772/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62773/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62774/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62775/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62776/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/62777/?format=api" ], "dataLineage": "Data were collected, quality controlled and prepared for archiving by the instrument scientists before upload to the Centre for Environmental Data Analysis (CEDA) for long term archiving.", "removedDataTime": null, "removedDataReason": "", "language": "English", "identifier_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/12294/?format=api" ], "projects": [ "https://api.catalogue.ceda.ac.uk/api/v2/projects/37021/?format=api" ], "observationcollection_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/39477/?format=api" ], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182170/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182171/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182172/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182173/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182174/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182175/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182176/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/182177/?format=api" ], "procedureAcquisition": "https://api.catalogue.ceda.ac.uk/api/v2/acquisitions/37048/?format=api", "procedureCompositeProcess": null, "procedureComputation": null, "permissions": [ { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/2522/?format=api", "useLimitation": null, "accessConstraints": null, "accessCategory": "registered", "accessRoles": null, "label": "registered: None group", "licenceURL": "http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/", "licenceClassifications": "any" } ], "discoveryKeywords": [] }
