| Popis: | We prove the possibility of creating a temperature dependent multi-relaxation spectroscopic dielectric model (TD MRSDM) for a set of organic soil containing 50% (Yamal tundra), 80% (Alaskan tundra) and 90% (boreal pine litter) of organic solids. The created model is based on the previously developed TD MRSDM for the Yamal tundra soil complemented with specific temperature dependences for the hydrological parameters pertaining for each specific soil. At that, the same values for spectroscopic and thermodynamic parameters of the TD MRSDM can be applied, as those were previously obtained in the case of the Yamal tundra soil. The statistical evaluation of the errors for the predicted values of complex dielectric permittivity in the cases of both the thawed and frozen soils with respect to the measured values were carried out. The standard deviations calculated for the Alaskan soil and the Siberian boreal litter appeared to be on the same order as the ones pertaining to the Yamal tundra soil. |
