Flood extent forecasting in Poyang Lake using TMSF-Net

Data availability statement This study uses six types of third-party data for flood extent forecasting in Poyang Lake. The SAR-derived surface-water maps are available at https://lake.geodata.cn/data/datadetails.html?dataguid=118284467501001&docid=5 and are described by Li et al. (2025), doi:10.18307/2025.0247. The Copernicus GLO-30 DEM is available at https://doi.org/10.5069/G9028PQB and was provided by the European Space Agency (2024). The GLC_FCS30D land-cover dataset is available at https://doi.org/10.5281/zenodo.8239305 and is described by Zhang et al. (2024), doi:10.5194/essd-16-1353-2024. The CHM_PRE V2 precipitation dataset is available at https://doi.org/10.11888/Atmos.tpdc.300523 and is described by Hu et al. (2025), doi:10.5194/essd-17-3987-2025. The CMFD v2.0 air temperature data are available at https://doi.org/10.11888/Atmos.tpdc.302088, with the original CMFD dataset described by He et al. (2020), doi:10.1038/s41597-020-0369-y. The GLASS MODIS-based surface net radiation product, version V50, is available at https://glass.hku.hk/archive/RN/MODIS/ and is described by Liang et al. (2023), doi:10.11834/jrs.20232462. All the above datasets are freely accessible for academic research through their original repositories or data providers. The data used for model training and evaluation were processed from these third-party datasets following the procedures described in Section 2.
