Monitoring the Snow and Growing Seasons

Submitted by atripp on

The snow season has become shorter and the growing season longer over the past 20 years in Alaska's Arctic National Parks. The NPS Arctic Inventory and Monitoring Network (ARCN) uses MODIS (Moderate Resolution Imaging Spectroradiometer) satellite images and remote automated cameras to monitor the timing of the growing season and the snow cover in five large national parks in northern Alaska.
