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`

    "title": "MODIS Surface Reflectance Product from the Terra Satellite (MOD09)",
    "abstract": "The MODIS Surface Reflectance Product from the Terra satellite is a level 2 data product derived from 7 spectrum bands (bands 1-7 each centred at 648 nm, 858 nm, 470 nm, 555 nm, 1240 nm, 1640 nm, and 2130 nm, respectively) from the Level 1B product. The product estimates the surface spectral reflectance as it would have been measured at ground level in the absence of atmospheric scattering or absorption. Corrections to account the effect of atmospheric gases, aerosols and thin cirrus clouds are made by using level 1B, other level 2 and level 3 products, and if necessary also climatology. Both the MOD09 dataset from the Terra satellite and the MYD09 dataset from the Aqua satellite are produced using the same processing system.",
