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`

This was collected as part of the NERC Reconciling Volcanic Forcing and Climate Records throughout the Last Millennium (Vol-Clim) project, which aims to resolve the discrepancy between climate model simulations and data on the magnitude of temperature changes caused by large-magnitude volcanic eruptions.\r\n\r\nThe 9 NetCDF files provide 10 years of zonal mean,  monthly-mean 1.5m air temperature data and the top of atmosphere outgoing longwave and shortwave fluxes for 9 UKESM1.0 realisations. Additionally, the \"emissions\" files for the stated eruption years provide the Stratospheric Aerosol Optical Depth (SAOD) at 550nm.\r\n\r\nThe CSV files provide monthly-mean, global mean or northern-hemispheric mean data for UKESM1, CESM2 (WACCM6ma), MPI-ESM1-2-LR, MRI-ESM2, MIROC-ES2L, and IPSL-CM6A-LR. We provide SAOD at 550nm for UKESM, CESM2, and MRI, with all models providing 1.5 air temperature.\r\n\r\nMarshall, L. R., Schmidt, A., Schurer, A. P., Abraham, N. L., Lücke, L.
