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`

    "abstract": "In situ observations of atmospheric aerosols (optical particle counter) and basic meteorological parameters collected during two seasons on the Greenland Ice sheet for the Black and Bloom project.\r\nBlack and Bloom is a research project, funded by the UK Natural Environment Research Council (NERC), that aims to unravel how dark particles (black) and microbial processes (bloom) darken and accelerate the melting of the Greenland Ice Sheet.  The data has been collected during two distinct field seasons (July 12 – August 18, 2016 and June 1 – 28, 2017). During this time there were instrument outages and also the aerosol samplers were turned off during helicopter activity.\r\nThese particulate measurements were used to estimate deposition velocities.\r\nOffline DNA (OTU) analysis are included from air samples collected during the campaigns as well as Scanning Electron Microscope (SEM) particle size analysis.\r\nIn addition (in a seperate folder), ten-day  particle dispersion calculations made using the FLEXPART model initiated from the ground site (67.07° N, 49.38° W 1073 m Above Mean Sea Level)",
