- Description
- Root zone soil moisture and its distribution throughout the profile play an important role in agricultural productivity and drought monitoring. An inversion scheme including the stratified coherent models of Njoku and Wilheit were employed to retrieve the daily soil moisture profile at 6 AM from simulated L-band and P-band radiometry observations for April 2019 in Cora Lynn, Victoria, Australia. Different levels of noise up to 4 K were imposed in this synthetic study. The average RMSE of retrieved soil moisture at the surface, middle, and bottom (60 cm) of the profile for the Njoku (Wilheit) model were 0.01 (0.04), 0.04 (0.06), and 0.05 (0.07) (all in m3/m3) when a second-order polynomial function was considered as the representative of the soil moisture profile.
