Interpretive Summary:

Technical Abstract: A testbed for comparing in situ soil moisture sensors was initiated by USDA and Oklahoma State University in2010 in cooperation with the NASA Soil Moisture Active Passive mission. This testbed was sited in Marena, Oklahoma on the Oklahoma State University Range Research Station. The testbed consists of four base stations, each consisting of different soil moisture sensors installed in profiles to compare their performance. Multiple stations enabled replication of the measurements, while also support the investigation of larger spatial distributions of soil moisture. These include stations from the COSMOS network, GPS Reflectometry Network, Climate Reference Network, and active and passive Distributed Temperature Systems. For the first deployment of sensors, calibration and scaling analysis was performed and most sensors are able to perform with an error less than 0.04 m3/m3, when compared to a gravimetric sample, but site specific calibration is necessary for most of the sensors. Additional sensors have been deployed recently as technologies have been developed and sensors have been replaced.
