《Dynamic b_p in the L Band and Its Role in Improving the Accuracy of Soil Moisture Retrieval》
The simulated brightness temperature(TBsim)was computed based on the optimized bp with time-varying characteristics and the default bp with a value of 0.12.Fig.4 compares TBsim with the airborne PALS brightness temperature(TBair);TBsim is positively correlated with TBair for both H and V polarizations.The statistical parameters for TBsim and TBair for both H and V polarizations are summarized in Table 1.The rms error(rmse)and bias of TBsim and TBair for bp=0.12 are both higher than those for the dynamic bp for both H and V polarization,and conversely the R2 values for TBsim and TBair are both higher with the dynamic bp.These results show that when modeling the brightness temperature of vegetated soil,it is better to use a dynamic bp than to fix the value as bp=0.12.
