Abstract	The soil moisture datasets collected at ARM facilities originates from two different instruments. SWATS instrument measure soil moisture in two different profiles at 8 depths from 0,05 to 1,75m, the SEBS instrument measure three profiles in depth of 0,025m. The site is managed by U.S. Department of Energy as part of the Atmospheric Radiation Measurement Climate Research Facility.
