Alaska + Arctic Geospatial Data API

The endpoints here provide access to the design thawing index and design freezing index.

Endpoint	Description
thawing	The mean of the three highest cumulative annual degree days from the thawing index for each era.
freezing	The mean of the three highest cumulative annual degree days from the freezing index for each era.

Query for the historical design thawing index at a provided point:

Query for the projected design thawing index at a provided point:

Query for the historical and projected design thawing index at a provided point:

Query for the historical design freezing index at a provided point:

Query for the projected design freezing index at a provided point:

Query for the historical and projected design freezing index at a provided point:

Results from the queries above will look like this:

{
  "2040-2069": {
    "di": 3787
  },
  ...
}

The above output is structured as such:

{
  <era>: {
    "di": <mean of degree days across top three years across models and era>
  },
  ...
}

The following queries will fetch design index values across all available models.

Results from the query above will look like this:

{
  ...
  "GFDL-CM3": {
    "2040-2069": {
      "di": 1548
    },
    "2070-2099": {
      "di": 775
    }
  },
  ...
}

The above output is structured as such:

{
  <model>: {
    <era>: {
      "dd": <mean of degree days across top three years across era>
    },
    ...
  }
  ...
}

To export the point data in a CSV file, append ?format=csv.
