Prior to evaluating errors in LAI estimation, the goodness of fit of the
parameterized WCM model was assessed using calibrated data in a forward
modeling approach. Different canopy structures can drastically affect
SAR response and thus unique equationswere created for both corn
and soybeans. As well, backscatter response is frequency and polarization
dependent. As a result, separate equations (Eq. (7)) were created
for each crop-frequency-polarization combination, yielding 12 different
equations.
