TY - Data T1 - 1-km spatial dataset of soil hydraulic parameters on the Loess Plateau (WGS84) A1 - Bai Xiao A1 - Sun Mingyang PY - 2026 DA - 2026-09-10 PB - National Cryosphere Desert Data Center AB - This dataset provides 1-km spatial distribution data of soil hydraulic parameters in the Loess Plateau region. Data include soil bulk density (BD), saturated hydraulic conductivity (Ks), van Genuine model parameters α and n, residual water content (θr), and saturated water content (θs), covering soil layers of 0 - 10 cm, 10 - 20 cm, 20 - 40 cm, 40 - 60 cm, 60 - 80 cm, 80 - 100 cm, 100 - 150 cm, 150 - 200 cm, 200 - 300 cm, 300 - 400 cm and 400 - 500 cm. The data is based on the observation results of the sampling points and spatial interpolation is performed using the ordinary kriging method. Kriging analysis was performed in the CGCS2000/3-degree Gauss-Krüger zone 36 (EPSG:4524) coordinate system, and the analysis cell size was 1000 m; the final released data was converted to the WGS84 (EPSG:4326) coordinate system, and the output grid cell size was 0.01°, which is equivalent to approximately 1 km in the study area. The data is provided in GeoTIFF format and contains relevant spatial reference files, processing parameters and data description files, which can be used for soil moisture simulation, hydrological analysis, soil and water conservation research, and ecosystem research.
