mode). SAR backscatter was only weakly correlated with 
soybean LAI. The highest correlations were reported at C-band 
(r=0.58-0.80). X-band backscatter was poorly correlated with 
both com and soybean LAI. 
The water cloud model was used to parameterize the 
relationship between LAI and soil moisture, and SAR 
backscatter at L- and C-band. The correlation between SAR 
backscatter and LAI didn’t show significant improvement 
following implementation of the model. Further research will 
couple soil moisture models and/or in situ network data with 
the water cloud model to improve parameterization of the 
contribution from the underlying soil.
