Abstract

Soil moisture (SM) dynamics regulate the exchange of water, energy, and biochemical fluxes between land and atmosphere. Consolidated earth observation SM products are available at low resolution (e.g., 3-40 km) globally, but higher resolutions are still under research. Surface heterogeneity in soil properties, land use, and vegetation cover can hinder SM retrieval. This paper aims to illustrate the effects of surface roughness anisotropy, canopy structure, vegetation water content, and precipitation patterns on SAR and optical observations at a resolution of approximately 100 m. Case studies and strategies to improve high-resolution SM retrieval will be discussed.
