Coastal exposure index of sea ice in Antarctica
Entry ID: AAS_4116_Coastal_Exposure

Abstract: This is a simple index which looks at the 360x1-degree longitudinal wedges around the Antarctic continent to see if there is any sea ice (where sea ice concentration is greater than 15%) to the north of the continent in each of these wedges.
The index goes from 0 (sea ice to the north off the continent in every longitude wedge) to 360 (no sea ice around the continent at all.

Purpose: Can be used as a tool to examine summer-time sea ice cover and also a tool in which you can compare observation data with model output.
