Effect of Tree Phenology on LiDAR Measurement of Mediterranean Forest Structure
2018
Remote Sensing
Preserved Fulltext
Retrieval of forest biophysical properties using airborne LiDAR is known to differ between leaf-on and leaf-off states of deciduous trees, but much less is understood about the within-season effects of ...
Our demonstration of which variables are more or less affected by spring-time leafing phenology has important implications for analyses of both canopy and sub-canopy vegetation layers from LiDAR surveys ...
We are grateful for the cooperation of all involved. Our thanks to Ruben Valbuena for comments on an earlier draft of this paper.
