  1. Note. HHP, NWR, SCB represent the agroecological zones of the Huang–Huai–Hai Plain, Northwest Region, and Sichuan Basin, respectively. There are no standard names for these three products; in this paper, we use names based on the corresponding algorithm or the resolution of the data. TWDTW stands for time-weighted dynamic time warping, PTDTW for phenology–time weighted dynamic time warping and ATDG for automated training data generation.
