The distinction between the glottis and background reflectance distribution can be observed from the clear bimodal structure in Figure 14(a).
In this mid-Arctic ecosystem, soil background reflectance tends to be very high (i.e., red and NIR reflectance ~ 0.3) and shadow is minimal, given the very low vertical structure of the vegetation.
The imperfect performance of the Crop Residue Index Multiband model was in part attributed to variability in soil background reflectance as evidenced by scatter of bare fields around an idealized soil line.
