Interactions among land cover, disturbance, and productivity across Arctic-Boreal ecosystems of Northwestern North America from remote sensing

Arctic and Boreal ecosystems are experiencing accelerated carbon cycling that coincides with trends in the normalized difference vegetation index (NDVI), a widely used remotely sensed proxy for vegetation productivity. Meanwhile, a variety of processes are extensively altering Arctic-Boreal land cover, complicating the relationship between NDVI and productivity. Because high-quality information on land cover is lacking, understanding of relationships among Arctic-Boreal greenness trends, productivity, and land cover change is lacking. Multidecadal time series of moderate resolution (30 m) reflectance data from Landsat and high resolution (
