Poggio et. al 2021 mean SoilGrids 2.0 sand and clay contents

Mean SoilGrids 2.0 sand and clay contents at 250m resolution. The reprojected 1-arcsec resolution version of this dataset served as input for estimating both static and transient water table depths across the contiguous United States (CONUS) at a 1-arcsec resolution.

Dataset Name: poggio_2021

Data Source: poggio_2021

Data Collection or Processing Notes:

This dataset is derived from averaging the 250m resolution sand and clay contents from SoilGrids 2.0 over six layers ranging from 0 to 200 cm. It is then reprojected to the CONUS2 1-arcsec grid.
