LIAISE Soil Moisture Estimation CESBIO v1

This dataset includes 3 maps at 100m resolution of surface soil moisture ( SSM ) using airborne measurements based on the GLObal Navigation Satellite System Reflectometry Instrument, a polarimetric instrument. GNSS-R measurements were acquired at the agricultural Urgell site in Spain in July 2021. The 3 maps available in this dataset correspond to 3 periods (July 22/27/28 at mi-day, flights as45 as46 as47) with different pluviometry : dry, after inundation event, and one during the drying process. The SSM maps generation is described in the following paper : M. Zribi et al., "Airborne GNSS-R Polarimetric Multiincidence Data Analysis for Surface Soil Moisture Estimation Over an Agricultural Site," in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, vol. 15, pp. 8432-8441, 2022, doi: 10.1109/JSTARS.2022.3208838. The SSM products in this dataset correspond to an update done in march 2023 using the L1b product avalaible in the LIAISE database : https://doi.org/10.25326/494 ?? = 0.058 ????? + 0.28 ???? +0.73
