Figure 5. Two dimensional contour maps of multi-temporal surface soil moisture derived from ESTAR 
brightness temperature. Patterns of soil moisture variation observed within the shaded areas closely 
follow the distribution of loam, silt loam, and clay loam, while the unshaded areas follow the distribution 
of sand, loamy fine sand, and fine sandy loam as shown in figure 7.
