Field notes
The method uses multi-date composites to address cloud gaps, with rice NDVI curves and pond-area change maps presented as outputs. The page says its validation hid real satellite observations, compared three reconstruction approaches under three cloud-detection settings, and corrected both a missing-data classification bug and a test-scoring bug. It also explicitly limits the reported study to three locations.
