Accurate estimates of forest canopy height and biomass are needed at local, regional and national scales in support of natural resource management as well as climate/carbon cycle researches. This project presents the theory and test of a model for estimation of maximum canopy heights and aboveground biomass in forest stands. The model is based on principles borrowed from Allometric Scaling and Resource Limitations (ASRL) theory, and combines related geospatial predictors and physiological/biophysical processes governing forest stand development. The model will incorporate all available in-situ and lidar/radar data (e.g., Geoscience Laser Altimeter System; GLAS) and/or existing forest canopy height maps (e.g., Lefsky 2010; Simard et al. 2011). Uncertainties related to spatial mismatch, divergence, and bias in input variables will be also discussed.
