Satellite remote sensing observations have the potential for efficient and reliable mapping of spatial soil moisture distributions. However, soil moisture retrievals from microwave remote sensing techniques are typically complex due to inherent difficulty in characterizing the interactions among land surface parameters that contribute to the retrieval process. Therefore, adequate physical mathe...
This paper addresses the use of capacitive measurement principles for process instrumentation. A brief review on capacitance-based sensors to measure industrial process parameters is provided. A capacitance-to-digital conversion system developed at the Sensors Group at our Institute is presented. Applications of capacitancebased process instrumentation for moisture sensing, flow velocity determ...
Recent studies have shown that a variety of remote sensing techniques may be used for the estimation of soil moisture over large areas. The shallow moisture sensing depth of passive microwave measurements, however, limits the use of remotely sensed soil moisture for many land–atmosphere interaction studies. In this study, a method is proposed for soil moisture profile estimation by sequential a...
