ASCAT-IB VOD Amazon dataset

ASCAT-IB VOD was developed based on the Water Cloud Model (WCM) coupled with the Ulaby linear model for soil backscattering.

The main features of IB VOD are that (i) the ERA5-Land soil moisture (SM) dataset was used as an auxiliary SM dataset in the retrievals, (ii) pixel-based soil model parameters were mapped using Random Forest (RF), and (iii) the vegetation model parameter was calibrated for each day.
