Landsat-based snow persistence map for northwest Alaska

The authors analyzed over 11,000 satellite images to characterize snow persistence at high spatial resolution over the range of the of the Western Arctic caribou herd: an area of over 500,000 square kilometers. Snow cover influences caribou winter distribution and habitat availability by impacting the energy required for traveling and foraging for food. The snow persistence map was co-registered to Landsat land cover mapping, creating a powerful, publicly available resource for ecosystem and land use analyses.
