In this work we focus on the inversion of soil surface parameters from L-band polarimetric Synthetic Aperture Radar (SAR) data acquired through the Terrain Observation by Progressive Scan (TOPS) operational mode. To this aim, the inversion procedure based on the Polarimetric Two-Scale Model (PTSM) is here applied for the first time to TOPSAR images to retrieve the soil permittivity and the soil roughness; specifically, Quad-Pol (QP) TOPSAR SAOCOM-1 data collected between June and November 2021 over La Pampa province, in Argentina, are here considered. In addition, the obtained soil permittivity estimates are compared with the available in-situ measurements.
