Abstract :
As an alternative to TDR or capacitive sensors, a monopole antenna has been tested for field measurements of liquid water content in both soil and snow. The frequency of operation is in the range of 100 MHz up to 2 GHz. Comparative field measurements of wetness profiles at snow-soil interfaces are shown
