Global carbon balance of the forest: satellite-based L-VOD results over the last decade

Frontiers in Remote Sensing
Monitoring forest carbon (C) stocks is essential to better assess their role in the global carbon balance, and to better model and predict long-term trends and inter-annual variability in atmospheric CO2 concentrations.
