Abstract

Temporal stability analysis (TSA) of volumetric soil moisture at 5 and 20 cm depths were conducted in an effort to determine the adequacy of permanent in situ monitoring sites to estimate field and watershed scale mean soil moisture within the Upper Cedar Creek Watershed (UCCW) monitoring network in northeastern Indiana. In general, results indicate that the analyses are sensitive to the scale observational data and therefore, depend on the specific research objectives in terms of appropriate data appications. At the field scale, locations that were optimal for estimating the area-average water contents were different from the permanent sensor locations. However, minimum offset values could be applied to the permanent sensor data to obtain representative field average values of surface soil moisture
