Recent climate warming has resulted in substantial changes in vegetation production at high northern latitudes (above 60°N). Understanding the direction, magnitude, and rate of these changes warrants investigation given that tundra and boreal biomes play important roles in global energy partitioning and carbon sequestration. Satellite-based measures of aboveground production have indicated both positive and negative trends across tundra and boreal biomes over the last 30 years, respectively. The purpose of this research was to examine the relationship between the remotely-sensed normalized difference vegetation index (NDVI), a widely used indicator of primary production, and interannual variation in ring-widths of dominant coniferous [...]
