Lidar remote sensing of savanna biophysical attributes
MetadataShow full item record
Although savanna ecosystems cover approximately 20 % of the terrestrial land surface and can have productivity equal to some closed forests, their role in the global carbon cycle is poorly understood. Studies using Light Detection And Ranging (Lidar) have demonstrated the sensor’s ability to measure canopy height, that is in turn strongly related to biophysical attributes such as aboveground carbon storage, but most of this work has focused on closed canopy forests. The sparse observation network in savannas means they remain one of the weak links in our understanding of the global carbon cycle. ...
