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 Africa-wide soil moisture and related water balance variables produced within the Earth Observation Climate Information Service (EOCIS) project.\r\n\r\nThe product is derived using the JULES land surface model, forced with TAMSAT satellite rainfall estimates and other meteorological variables from the NCEP reanalysis, and tuned to NASA SMAP satellite soil moisture observations. Data are provided at the daily scale, from 1983-01-01 to present (latency around 7 days) at 0.25 degrees by 0.25 degrees spatial resolution.\r\n\r\nUsers should note that, due to challenges in estimating root-zone soil moisture, large differences can occur between datasets. As a result, absolute root-zone soil moisture values (including those from TAMSAT-SM) should be interpreted with caution when comparing across different products.\r\n\r\nFor further details, please visit the TAMSAT website (https://www.tamsat.org.uk)",
