Paper Abstract

The Vegetation Canopy Lidar (VCL) is scheduled for launch in 2000 as the first mission of NASA's new Earth System Science Pathfinder Project. It will provide unique dataset on canopy geometry and sub-canopy topography, which will lead to improved understanding of important structures and processes of Earth environment. To understand the relation between canopy structure and the Lidar waveform, a 3-d model is implemented in this study. Various forest stands were used to parameterize this vegetation lidar waveform model including (1) simulated stands at various ages from forest growth model, (2) forest stand with detailed field measurements, and (3) simulated forest stands with different spatial tree distributions. The simulated lidar waveforms for various stands were presented and the results were discussed in this paper.
