Results for discrete homogeneous scenes are exhibited in the following Figure, which shows the various contributions of the models to a series of histograms of local angular model deviation values estimated for viewing conditions in the principal plane (left panels), cross plane (middle panels) and the principal and cross planes together (right panels). The top, center and bottom panels display the results obtained at the red, the near-infrared and, at the red and near-infrared wavelengths together, respectively. As such, this figure demonstrates the large spread of results delivered by a set of 8 BRF models participating.

The values obtained when estimating the local model deviation at the near-infrared wavelength reflects mainly the difference in the methods used to estimate the multiple scattering components in the plant-soil system. The following Figure thus shows the detailed contributions of the individual models to a series of histograms of local angular model deviation values for the multiple scattering component only (under the same conditions of averageing as before):

The following figure displays the angular deviations of the various models (with respect to each other) as a function of viewing angle, averaged over both erectophile and planophile leaf normal distributions in the case of the discrete homogeneous environments, along the principal plane, at two solar zenith angles (20 and 50 degree), and for both the red and near-infrared wavelengths:

The following figure is similar to the previous but shows the angular deviations of the various models (with respect to each other) as a function of viewing angle, averaged over both erectophile and planophile leaf normal distributions in the case of the discrete homogeneous environments, along the orthogonal plane, at two solar zenith angles (20 and 50 degree), and for both the red and near-infrared wavelengths:
