agricultural nitrogen surplus.CANSD v1.0 provides annual agricultural nitrogen surplus (NS) data for China from 2000–2022, with a spatial resolution of 0.5° ×0.5°and units of ktN. The dataset is deposited at Figshare (https://doi.org/10.6084/m9.figshare.29557823) as a compressed folder (file format: ZIP) containing 23 GeoTIFF (.tif) files. The directory structure is straightforward: all files are stored in a single root folder, with filenames following the convention "ns20XX.tif" (e.g., "ns2000.tif" for 2000, "ns2022.tif" for 2022). Maps can be visualized and analyzed using GIS software such as ArcGIS, QGIS, or other compatible applications.Yanyi Li,Li He, Mengxi He, Zhenjie Tang, Yuxuan Wang
