Instrumentation

Continuous measurements of soil moisture are performed with sensors based on time domain reflectometry (TDR) and capacitance techniques. The TDR sensors TRIME-EZ, TRIME-IT (IMKO GmbH), and the capacitance sensor 10HS (Decagon Devices, USA) are used at the SwissSMEX sites. Soil temperature is measured continuously with the 107-L sensors (Campbell, USA).
