Correlation between Ground Measured Soil Moisture and RADARSAT-1 derived Backscattering Coefficient over an Agricultural Catchment of Navarre (North of Spain)

The presented technique is useful for crop growth monitoring and modelling at medium to large scales, particularly in early growing seasons where the attenuation of vegetation is not too high. It is also applicable to irrigation planning or crop health studies. However, regression lines are site specific and can be affected by the surface roughness variability and vegetation cover of fields.
