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": "The UK Earth System Model (UKESM1) has been used to produce two simulations for the Climate Services for a Net Zero Resilient World (CS-N0W) research programme. The first simulation (\"no overshoot\" or NO) was designed to fix global-mean annual-mean surface temperature to 1.5C above pre-Industrial levels from 2010-2100, and the second simulation (\"very high overshoot\" or VHO) was a scenario where global-mean annual-mean surface temperature was allowed to rise above 1.5C during the century but return to 1.5C by 2100. Four ensemble members were run for each scenario.\r\n\r\nThese are based on the UKESM1-0-LL model. Forcings followed the SSP2-4.5 Shared Socio-economic Pathway, except for chemistry and aerosol emissions which followed SSP1-1.9. CO2 and N2O concentrations were calculated used the TIMES Integrated Assessment Model at University College London (TIAM-UCL) model, which was also used to calculated CH4 for the NO simulation. CH4 in the VHO simuation used SSP1-1.9.",

Data was archived to the Met Office MASS archiving system, and processed on JASMIN, the UK collaborative data analysis facility. Simulations were branched from UKESM1-0-LL r1i1p1f2, r3i1p1f2, r11i1p1f2, and r18i1p1f2 historical ensemble members in 2010. The final dataset was then uploaded to CEDA.",
