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`

This data was collected as part of the Quantification of Utility of Atmospheric Network Technologies: (QUANT) project, specifically Work Package 1 which had the objective to deliver 'Transparent assessment of commercial low-cost sensor devices in multiple UK urban environments'. The three sites are the Manchester Air Quality Supersite (MAQS), London Air Quality Supersite (LAQS), and the Fishergate Automatic Urban and Rural Network (AURN) monitoring site in York. MAQS and LAQS are urban background locations, while Fishergate is a roadside site. The devices report a range of species, with every device measuring either NO2 or PM2.5, with the vast majority recording both. The data was collected over the period 2019-12-10 to 2022-10-31, with half the devices being deployed throughout this entire period and the other half starting in July 2021 as part of a side-study referred to as the Wider Participation Study.\r\n\r\nQUANT was funded as part of the NERC led UKRI Strategic Priorities Fund Clean Air program (grant no.
