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`

Wind speed and direction are measured by a WINDCAP (R) sensor which consists of an array of three equally-spaced ultrasonic transducers. These transducers are situated approximately 11 cm apart in a horizontal plane, leading to minimum, mean, and maximum values of speed and direction to be recorded. Data are available in netCDF formatted data files to all CEDA registered users under the UK Open Government licence.\r\n\r\nThis instrument has since been replaced by a Vaisala WXT520 surface meteorology instrument at the site.\r\n\r\nNote - the wind data from this instrument are known to be highly constrained by the valley topography in which the instrument is sited. As such it should not be used as a representation of the broad scale wind field, but may be of interest to those wishing to study valley flows.", "keywords": "MST, meteorology, surface, 2m, wind speed, wind direction", "publicationState": "citable", "dataPublishedTime": "2008-08-28T14:28:05", "doiPublishedTime": "2018-01-31T11:37:10", "updateFrequency": "notPlanned", "status": "completed", "result_field": { "ob_id": "https://api.catalogue.ceda.ac.uk/api/v2/observations/6147/?format=api", "dataPath": "/badc/mst/data/wind-sensors-wxt510", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 113750423, "numberOfFiles": 2496, "fileFormat": "Data are CF-compliant NetCDF formatted." }, "timePeriod": "https://api.catalogue.ceda.ac.uk/api/v2/times/3415/?format=api", "geographicExtent": "https://api.catalogue.ceda.ac.uk/api/v2/bboxes/515/?format=api", "nonGeographicFlag": false, "phenomena": [ "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/1633/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/8238/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/8239/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/8240/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/8241/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21515/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21516/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21517/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21518/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21519/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/21520/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/phenomona/25407/?format=api" ], "dataLineage": "These data were acquired by the MST radar facility and sent to the BADC (subsequently CEDA) within an hour of acquisition.
