In remote and vast Arctic areas satellite and aerial imagery provide insights into permafrost thaw processes on a regional scale which we would not gain from measurements at the surface. Remote [...] sensing component of the project, therefore, addresses the following research questions: 1. How do permafrost erosion features respond to changes in meteorological conditions? 2.
