Photosynthetic Activities in Northern Circumpolor High Latitudes

Caption

This map shows characteristic trend patterns in photosynthetic activity for different land cover types. Areas with significant trends are showing through while insignificant trends are opaque. The trends are colored according to magnitude of the greening or browning. The upper left image shows the widespread greening occurring on the tundra areas north of the Brooks Range in Alaska (the mountains themselves show no significant trends). The upper right subset shows negative trends in the interior forests of Russia, while the bottom image shows a transition from positive to negative trends as a boundary from forest to wetlands is crossed.
