Need a cryosphere example for NASA Earthdata icepyx tutorial

[andypbarrett]

The NASA Earthdata Cloud Access, icepyx tutorial uses ATL08 - a vegetation product. We need a more icy example.

I think having an ATL08 example and a cryosphere example is a good approach.

If we follow the "search by polygon" approach.

1. What is a good search location? Jakobhavn?
2. Is there an example of ice edge retreat that we can show?
