Abstract

En 中文

• Transferred scattering-model priors to Sentinel-1 for 10-m soil moisture retrieval • Hybridized model transfer with fine-tuning for interpretability and generalization • Corrected vegetation effects via deep learning without in situ vegetation parameters • Achieved accurate retrieval in vegetated areas without surface roughness parameters
