Abstract

Ground measurements and remotely sensed measurements of soil moisture are foreseen at selected sites in the Lago Maggiore (Val d'Ossola) target area during special and intensive observing periods of MAP, planned for next September-November 1999. The Osservatorio Geofisico (University of Modena) working group will collect soil volumetric water content measurements by means of Time Domain Reflectometry (TDR) technique. The TDR system is equipped with a multiplexer so that many probes can be automatically scanned at fixed time intervals. The probes were installed at the end of March 1999 in the middle of a uniform meadow suitable to be seen by an airborne microwaves radiometer. Fourteen TDR wave-guides were buried at different depths in the first 70 cm soil layer. The readings are collected each four hours to compute, from the soil water content profile trend, the cumulative evaporation during the MAP SOP campaign and to be used as ground truth data for the remotely sensed measurements.
