GET

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`

    "abstract": "This dataset contains output from 5 climate model experiments conducted as part of the North Atlantic Hosing Model Intercomparison Project. The experiments use idealised forcing, including adding hosing (additional surface fresh water) over the North Atlantic and Arctic. These experiments are:\r\n•\tu03-hos - constant uniform hosing of 0.3 Sv. \r\n•\tu03-r50 - experiment with no hosing initialised 50 years into u03-hos\r\n•\tu03-r70 - experiment with no hosing initialised 70 years into u03-hos\r\n•\tu03-r100 - experiment with no hosing initialised 100 years into u03-hos\r\n•\tg01-hos – hosing around Greenland of 0.1Sv\r\n\r\nEight CMIP6 global coupled climate models took part (note that only some have conducted u03-r70 and u03-r100). The data is presented in gridded netcdf format with the intention of providing standardised data following the CMIP6 data request and CF metadata convention. The equivalent data with no hosing is available from the preindustrial control simulations from the CMIP6 database",
