Measuring and Modeling the Effect of Surface Moisture on the Spectral Reflectance of Coastal Beach Sand
Figure 6
Performance of the optical model (Eq. 6).
Top panel: goodness of fit 
of the optical model as function of volumetric moisture content. Bottom panel: trajectories of the regression parameters 
and 
of the optical model, describing the proportional contribution of scattering (fraction 
) and absorption (optical path length in water 
) as moisture levels increase. Shaded areas indicate 95% confidence intervals.
