Observation Instance – Django REST framework

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`

    "abstract": "Scan data from the National Centre for Atmospheric Science Atmospheric Measurement and Observation Facility's mobile X-band radar unit 1 deployed at MOD Lyneham, near Swindon, Wiltshire, UK  (51.5071N, -2.00547E) from May to September 2023.  These observations were taken as part of the WesCon - Observing the Evolving Structures of Turbulence (WOEST) project between 20230525 and 20230908.\r\n\r\nData products from this deployment include: volume scans (vol) and vertical cross sections (rhi). The radar performed two sets of volume scans, alternating approximately every 5 minutes, using different parameters for targeting the boundary layer and clouds. Following the volume scans the radar performed a single vertical cross-section. The whole cycle repeated every 10 minutes. \r\n\r\nFor further details of this deployment and the associated dataset please see the internal file metadata.\r\n\r\nThese data conform to the NCAS data standards and are available under the UK Government Open Licence agreement. Acknowledgement of NCAS as the data provider is required whenever and wherever these data are used.",
