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 camera layout consists of three pairs of perspective cameras, arranged in a triangle and intersecting over the Chilbolton Atmospheric Observatory, along with a pair of all-sky cameras at Chilbolton.\r\n\r\nThe ARray of Ground-based Upwards-pointing Sensors (ARGUS) cameras were deployed over June and July 2023 and were operational until the end of September 2023. The cameras were scheduled to take images every 5 seconds. These images have been compressed to mp4 files to make them easier to retrieve over the 4G network during the observation period. Each file lasts one hour.
