Figure 3: Scatterplots of soil moisture calculations for SGP97 for June 25 (a, b) and June 2 (c, d). The scatterplots on the left show soil moisture retrieval using the original input parameters, whereas the scatterplots on the right show recalculated soil moisture using random combinations of vegetation water content, percent clay, and surface roughness. The mean 95% confidence limit for the majority of the distribution is shown on each plot.
