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": "This dataset contains UK Met Office Daily Weather Reports (DWR) from ten sites from the UK Met Office Monthly Weather Records (1884-1993), using the recently-scanned UK Met Office Monthly Weather Reports (MWR). The data are presented as is, with no attempt to provide any corrections  or calibration. Approximately half the stations exhibit sharp drops in thunderdays at various points between 1960 and 1990. Comparison with nearby Met Office Integrated Data Archive System (MIDAS) stations suggests the low thunderdays are the result of changes in observing practice, rather than genuine changes in thunderstorm  occurrence. These potential  data issues limit  interpretation of the long-term  trends. \r\n\r\n DWR  contain extensive logs of UK thunderstorm activity, in the form of thunderday observations.  To date, only a very small fraction of these data have been digitised as part of the MIDAS dataset, and exclusively after 1950.",
