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 project was lead by the University of Oxford and involved the Universities of Leeds, Reading, Sussex and the UK Met Office. Fennec investigated the Saharan climate system and the role of dust aerosols, involving a unique surface and aircraft field campaign with the FAAM BAe-146.\r\n\r\nVarious meteorological variables were collected at 3 min 20 second intervals, between 2011 and 2013 at 8 Automatic Weather Stations. Parameters include: 1m pressure, 3 min 20 sec mean 2m windspeed (sonic and cup anemometers), number of windspeeds sampled, variance of windspeed in sample, skew of windspeed in sample, 2m relative humidity, 2 temperature, soil temperature (2 depths), ground flux, shortwave radiation up and down, longwave radiation up and down. \r\n\r\nSpecific station locations are stated both in the data files and the CEDA platform record. One station had to be moved after the first year, hence there are 9 station locations listed.\r\n\r\nDue to harsh environmental conditions a number of the AWS stopped operating after deployment. Additional information regarding instrument issues and missing data can be found in a PDF on the CEDA archive. \r\n\r\n\r\n", "keywords": "Fennec, Sahara, Desert, AWS, surface pressure, 2 m windspeed, 2 m relative humidity, 2 m temperature, soil temperature, ground flux, shortwave radiation, longwave radiation", "publicationState": "published", "dataPublishedTime": "2017-05-23T14:18:43", "doiPublishedTime": null, "updateFrequency": "notPlanned", "status": "completed", "result_field": { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/24689/?format=api", "dataPath": "/badc/fennec/data/leeds-aws-f", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 231558526, "numberOfFiles": 24, "fileFormat": "The data comprise 22 NetCDF data files and 1 .pdf file which provides additional information about instrument issues.
