Pan–Arctic Sea Ice Concentration Point Query

This endpoint accesses historical monthly data on sea ice concentration in the Arctic from 1850–2021.

Historical queries for data at given latitude / longitude

Query the historical sea ice concentration at lat / lon:

Example: /seaice/point/63.73/−166.32

Results from the queries above will look like this:
  "1850-01": 100,
  "1850-02": 98,
  "1850-03": 96,
The above output is structured like this:
  "<year>–<month>": <sea ice concentration for one of the 12 months in a year>
