Dielectric spectroscopic model for tussock and shrub tundra soils

In this paper, the measured microwave dielectric data are presented for some soils collected in the tussock and shrub tundra area located on the North Slope, Alaska, near Toolik Lake, at N 68° 38’, W 149° 35′ with an elevation of 730m. The measured samples represented the organic rich soil picked up from the middle and base of tussock, organic poor soil from the depth of 20 cm in the valley between tussocks, and organic rich soil from the depth of 20 cm in the shrub tundra site. The measurements were carried out in the range of frequencies from 0.5 to 16.0 GHz and temperatures from −30°C to +25°C. On the basis of that data, the spectroscopic model of complex dielectric constant was developed for the moist soils measured, using the methodology of the generalized refractive mixing dielectric model
