General Overview

The Soil Water And Temperature System (SWATS) is designed to provide information about the temperature of the soil and the status of water in the soil profile. Sensors installed at various depths below the soil surface provide hourly measurements of soil temperature and estimates of soil-water potential and volumetric water content. SWATS systems are installed at 21 of the ARM SGP CART Extended Facilities (EFs). The SWATS instrument system is comprised of 16 sensors: eight sensors located at different depths in the soil profile, replicated in two profiles.
