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 ESA Sea Surface Temperature Climate Change Initiative (ESA SST CCI) dataset accurately maps the surface temperature of the global oceans over the period 1991 to 2010 using observations from many satellites. The data provides an independently quantified SST to a quality suitable for climate research. \r\nThe ESA SST CCI ATSR (Along-Track Scanning Radiometer) Long Term Product version 1.1 consists of stable, low-bias sea surface temperature (SST) data covering the period 08/1991 - 04/2012.  The L3U data product provides these SST data regridded onto a global longitude-latitude grid.\r\n\r\nThe version 1.1 data is an update to the version 1.0 dataset.\r\n\r\nThis dataset is cited in: Merchant, C.

These start in August 1991.\nEach file contains two sets of SSTs. The first set provides a measure of\nthe temperature of the skin of the water at the time it was observed; the\nsecond set are estimates of the temperature at 20 cm depth and at either\n1030 h or 2230 h local time. Each SST has associated with it a total uncertainty\nestimate, and uncertainty estimates for various contributions to\nthat total uncertainty.\n&lt;/p&gt;&lt;p&gt;\n\nThe data are stored in NetCDF-4 format files. Data arrays in NetCDF files are\nknown as &amp;#8216;variables&amp;#8217; and each variable has metadata stored with it. Please read the ESA CCI SST Product User Guide, available &lt;a href=\"http://www.esa-sst-cci.org/PUG/documents.htm\"&gt;here&lt;/a&gt; before using the data. There is also a Quick Start Guide &lt;a href=\"http://cedadocs.badc.rl.ac.uk/959/1/SST_CCI-QuickStartGuide-Issue-1.pdf\"&gt;here&lt;/a&gt;.\n&lt;/p&gt;&lt;p&gt;\nAccess to the ESA SST CCI ATSR L3U long term product is available through our data browser &lt;a href=\"http://neodc.nerc.ac.uk/browse/neodc/esacci_sst/data/lt/ATSR/L3U/v01.1\"&gt;here&lt;/a&gt; or via &lt;a href=\"ftp://ftp.ceda.ac.uk\"&gt;ftp&lt;/a&gt; at /neodc/esacci_sst/data/lt/ATSR/L3U/v01.1\n&lt;/p&gt;&lt;p&gt;\n\n\n&lt;/p&gt;&lt;/div&gt;\n\n\n"
