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 University of Salford radiometer data describe observations taken by microwave radiometer that was situated at the Faccombe wind turbine field site, Hampshire and collected data from 24th June 2005 until 26th August 2005. T\r\n\r\nThe dataset contains measurements of the following parameters:\r\n\r\nLiquid Water Path (LWP) time series – 1 second measurement time\r\nIntegrated Water Vapour (IWV) time series – 60 seconds measurement time\r\nHumidity Profile (full troposphere) (HPC) – 60 seconds measurement time\r\nTemperature Profile (full troposphere) (TPC) – 60 seconds measurement time\r\nTemperature Profile (boundary layer) (TPB) – 200 s measurement time\r\nA boundary layer temperature profile was taken every 10 minutes which took 200 seconds to complete. When not operating a boundary layer scan, the radiometer operated in zenith mode and measurements of LWP, IWV and the tropospheric temperature and humidity profiles were made. Calibrations were performed every 20 minutes, 6 hours and 24 hours.\r\n\r\nThe boundary layer temperature measurements (0 – 2000 m) have a vertical resolution of 50 m. The tropospheric temperature measurements (0 – 10000 m) have a vertical resolution of 200 m. The tropospheric humidity profiles (0 – 6000 m) have a vertical resolution of 200 m (0 – 2000 m) and 400 m (2000 – 6000 m).\r\n\r\nTwo jpeg images files have been produced from the radiometer data for each day from 24th June 2005 until 26th August 2005. The first image file contains separate profiles of temperature up to 2 km and 10 km and profiles of absolute and relative humidity up to 10 km. The second image file contains a time series of the integrated water vapour and liquid water path.",
