A China Dataset of soil hydraulic parameters pedotransfer functions for land surface modeling (1980)

This data uses soil conversion functions to take sand, silt, clay, organic matter, and bulk density as inputs to estimate soil hydrological parameters, including parameters of the Clapp and Hornberger function and van Genuchten and Mualem function, field water holding capacity, and withering coefficient. Median and coefficient of variation (CV) provide estimates.

The data set is in a raster format with a resolution of 30 arc seconds, and the soil is layered vertically into 7 layers with a maximum thickness of 1.38 meters (ie 0-0.045, 0.045--0.091, 0.091--0.166, 0.166--0.289, 0.289-- 0.493, 0.493--0.829, 0.829--1.383 meters).

The data is stored in NetCDF format. The data file name and its description are as follows:

1. THSCH.nc: Saturated water content of FCH

2. PSI_S.nc: Saturated capillary potential of FCH

3. LAMBDA.nc: Pore size distribution index of FCH

4. K_SCH.nc: Saturate hydraulic conductivity of FCH

5. THR.nc: Residual moisture content of FGM

6. THSGM.nc: Saturated water content of FGM

7. ALPHA.nc: The inverse of the air-entry value of FGM

8. N.nc: The shape parameter of FGM

9. L.nc: The pore-connectivity parameter of FGM

10. K_SVG.nc: Saturated hydraulic conductivity of FGM

11. TH33.nc: Water content at -33 kPa of suction pressure, or field capacity

12. TH1500.nc: Water content at -1500 kPa of suction pressure, or permanent wilting point
