Modeling and Simulation in Engineering
Preserved Fulltext
As a result, the present DART model simulates the radiation budget and remote sensing images of vegetation and urban canopies, for any experimental (sun direction, canopy heterogeneity, topography, atmosphere ...
Neglect of the 3D structure of canopies can lead to large errors on the 3D radiation budget and remote sensing measurements. ...
Only BRFs could be compared because DART was the only 3-D model that simulates images. ...
