Swot Cal/Val Campaign Based on the Swalis Airborne Sensor. Comparaison of σ0 over the Mont-Saint Michel Bay and over the Gondrexange/Stoke Ponds

This paper presents the first comparisons of backscattering coefficients σ
0
between acquisitions from the SWALIS (Still WAter Low Incidence Scattering) airborne sensor and the space mission SWOT (Surface Water and Ocean Topography) over the Mont Saint-Michel (MSM) bay and over the Gondrexange and Stoke ponds. The MSM area is chosen both as a calibration/validation area for the SWOT mission and as a perfect area for analyzing the backscattering of specific sand areas.
