This dataset provides 30 m soil sand content mapping products for cultivated lands in two representative black soil regions, Northeast China (NEC) and the Mississippi River Basin in North America (MNA), covering 2020–2024. The dataset includes two GeoTIFF (.tif) files: NEC_SoilSandContent_30m_2020-2024.tif and MNA_SoilSandContent_30m_2020-2024.tif. The products use the WGS 1984 coordinate reference system (EPSG:4326), with soil sand content expressed as a percentage (%).
