## 2 SAR Data, Field Data and Study Sites  
### SAR Data  
Multi-temporal X-band SAR Single Look Complex (SLC) data were obtained from the Italian Space Agency (ASI/e-GEOS) and GISTDA (Geo-informatics and Space Technology Development Agency) for COSMO-SkyMed (CSK) data and from InfoTerra GmbH for TerraSAR-X (TSX) data. In all cases, data were obtained in HH polarization with consistent incidence angles in each multi-temporal stack, ranging from 39 to 48 degrees across sites. A large incidence angle is preferred, because (i) wind effects on water (in particular, during land preparation prior to transplanting) are significantly decreased, (ii) the \begin{table}
