GNSS-R is a remote sensing technique that relies on the use of navigation signals reflected on the surface of the Earth. Principally devised with ocean applications in mind, the potential of this technique for land applications (soil moisture and vegetation biomass) has been explored through the use theoretical models, and demonstrated thanks to ground-based and airborne experimental measurements.As land surfaces are heterogeneous, it is important to assess the performance of this technique from a spaceborne standpoint, which is now possible thanks tothe availability of spaceborne GNSS-R observations.The objective of this activity is to analyze available spaceborne GNSS-R observations to consolidate the understanding of the GNSS-R technique over land and to assess its performance for soil moisture and vegetation biomass retrieval.
