Regional and landscape-scale variability of Landsat-observed vegetation dynamics in northwest Siberian tundra

Widespread increases in Arctic tundra productivity have been documented for decades using coarse-scale satellite observations, but finer-scale observations indicate that changes have been very uneven, with a high degree of landscape- and regional-scale heterogeneity. Here we analyze time-series of t...
