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`

The current version of the dataset is GICE23b.\r\n\r\nGISST/GICE was originally developed as an extention to MOHSST that provided a globally complete SST analysis and sea-ice data. This is required to drive atmospheric general circulation models.\r\n\r\nGISST/GICE has now been superceeded by HadISST. We now recommend use of HadISST instead of GISST/GICE for all purposes. GICE is only still available in case it is needed for direct comparison with earlier work where GICE was used. GICE is no longer updated or developed.\r\n\r\nThe sea-ice component of GISST (GICE) contains known inhomogeneities, especially in the antarctic. GISST should not be used for studies of sea-ice variability.\r\n\r\nGISST sea-ice fractions are based on a mixture of charts, satellite observations and statistical interpolations.\r\n\r\nThe current version of the dataset is GICE 2.3B which was provided by the Met Office.",
