An Air-to-Soil Transition Model for Discrete Scattering-Emission Modelling at L-Band

Figure 4

Comparisons of estimated dielectric roughness thickness () from the third (ATS-Wil), fourth (ATS-Lv), and fifth (ATS-Lv2.5) experiments, supported by comparisons of SM during the late-monsoon period. SM_Wil is the representative SM derived from Wilheit coherent model using the Fresnel equations (e.g., via minimizing the objective function of reflectivity difference). SM_Lv represents the weighted SM derived from Lv incoherent model and SM_2.5 cm refers to in situ measured SM at 2.5 cm.
