    A dielectric model at a frequency of 1.4GHz for frozen mineral soils in the temperature range −1 to −30°C / V. L. Mironov [и др.] // Progr. Electromag. Res. Symp.

   Перевод заглавия: Диэлектрическая модель на частоте 1,4 ГГц для мерзлых минеральных почв в температурном диапазоне от -1 до -30 °С
Аннотация: A single-frequency dielectric model at 1.4 GHz for frozen mineral soils was developed, with the temperature and clay content varying from -1 to -30°C and 9.1 to 41.3%, respectively. The model is based on dielectric measurements of three typical soils (sandy loam, silt loam, and silty clay) collected in the Yamal peninsular. The refractive mixing model was applied to fit the data aggregates consisting of measured complex refractive indexes (CRI) for the three soils as a function of soil moisture at a fixed temperature. As a result, there were derived the parameters of the refractive mixing dielectric model as a function of temperature and texture. These parameters involve the maximum allowed gravimetric fraction of bound water and the CRIs of soil solids, bound soil water, and free soil water components, the latter being represented by capillary ice. The error of the dielectric model was evaluated by correlating the predicted complex relative permittivity (CRP) values of the soil samples with the measured ones. The coefficient of determination, R2, and the root mean square error, RMSE, were estimated to be R2 = 0.994, RMSE = 0.22 and R2 = 0.988, RMSE = 0.07 for the real and imaginary parts of the CRP, respectively. These values are on the order of the dielectric measurement error itself. The proposed dielectric model can be applied in active and passive remote sensing techniques used in the Arctic areas, mainly for the SMOS, SMAP and Aquarius missions.

    A dielectric model of thawed and frozen Arctic soils considering frequency, temperature, texture and dry density / V. L. Mironov, A. Yu. Karavayskiy, Yu. I. Lukin, I. P. Molostov // Int. J. Remote Sens. - 2020. - Vol. 41, Is. 10. - P. 3845-3865, DOI 10.1080/01431161.2019.1708506. - Cited References: 39 . - ISSN 0143-1161. - ISSN 1366-5901
Аннотация: A dielectric model was developed for thawed and frozen mineral soils, based on the refractive mixing dielectric formula and the dielectric measurement data for three soils collected in the Arctic tundra of the Yamal Peninsula. The refractive mixing dielectric model was used in conjunction with the Debye multi relaxation equations as a theoretical model to fit the measured complex relative permittivity spectra as a function of soil moisture and temperature. As a result, the dielectric spectroscopic parameters for the various components of water in the soil, such as the low- and high-frequency limits of the complex relative permittivity, the times of the corresponding relaxations, and the specific conductivity, were simultaneously determined for soils with different clay contents for all measured temperatures. As the theoretical temperature dependences of these parameters, the Clausius–Mossotti, Eyring, and linear equations for the conductivity were used. By using approximations of the measured data with these formulas, the parameters of the temperature-dependent model were derived, such as the coefficient of volume expansion, energy and entropy of activation, and coefficient of thermal conductivity. A set of the parameters discussed above in conjunction with the refractive mixing formula is a temperature- and mineralogically dependent multi-relaxation spectroscopic dielectric model, which enables estimation of the permittivity of moist soils as a function of dry soil density, moisture, frequency, temperature, and texture. The statistical error of the proposed dielectric model was estimated in terms of the normalized root-mean-square error (nRMSE), which was equal to 5% and 25% for the dielectric constant and dielectric loss factor, respectively.

   Перевод заглавия: Диэлектрическая база данных органических арктических почв
Аннотация: This article presents a Dielectric database of organic Arctic soils (DDOAS). The DDOAS was created based on dielectric measurements of seven samples of organic-rich soils collected in various parts of the Arctic tundra: Yamal and Taimyr Peninsula, Samoilovsky Island (the Russian Federation), and Northern Slope of Alaska (U.S.). The organic matter content (by weight) of the soil samples presented varied from 35 % to 90 %. The refractive index (RI) and normalized attenuation coefficient (NAC) were measured under laboratory conditions by the coaxial waveguide method in the frequency range from ~ 10 MHz to ~ 16 GHz, while the moisture content changed from air-dry to field capacity and the temperature from −40 °C to +25 °C. The total number of measured values of the RI and NAC contained in the database is more than 1.5 million values. The created database can serve not only as a source of experimental data for the development of new soil dielectric models for the Arctic tundra but also as a source of training data for artificial intelligence satellite algorithms of soil moisture retrievals based on neural networks. DDOAS is presented as Excel files. The files of DDOAS are available on http://doi.org/10.5281/zenodo.3819912 (Savin and Mironov, 2020).

dielectric model -- moisture -- temperature -- organic soil -- frozen soil -- thawed soil
Аннотация: A dielectric model based on the refractive dielectric model of the mixture of thawed and frozen forest organic soils in the root zone for a frequency of 435 MHz has been developed. The model is created on the basis of dielectric measurements of four soils whose organic matter content varies in the range from 15 to 31%. The dielectric measurements are carried out in the range of the gravimetric moisture from 0 to 0.6 g/g and temperature range from –30 to 25°C. The coefficient of determination (R2) between values calculated by themodel and measured values of the real (ε') and imaginary (ε'') parts of complex dielectric permittivity is 0.97. The normalized root-mean-square error is 16 and 21% for the real and imaginary parts of the complex dielectric permittivity, respectively. This dielectric model may be applied in remote sensing algorithms when retrieving the value of forest soil moisture in the root zone from radar and radiometric data.

Аннотация: In this paper, the influence of organic-mineral Arctic tundra soils on own thermal radiation in the L-band was theoretically investigated. For modeling of brightness temperature there were used semi-empirical L-band Microwave Emission of the Biosphere (L-MEB) model. An integral part of this model is permittivity models of tundra organic and mineral soils, which links the brightness temperature with moisture, temperature and density of soil. The permittivity models were developed based on the measurements of the organic rich and mineral soil samples collected at the Vaskiny Dachi weather station test-site in Yamal peninsular. As a result, the potential error of soil temperature retrieval in case of layered and homogeneous organic-mineral soil are shown based on simulated brightness temperature at 1.4 GHz. © 2015 IEEE.

   Перевод заглавия: Частотно-, температурно-, и минералогически-зависимая диэлектрическая модель мерзлых и влажных арктических минеральных почв
Аннотация: A simple single-frequency dielectric model for the set of frequencies which are 0.45, 1.26, 1.4, 1.6, 5.4, 6.9, 9.6, and 10.7 GHz for frozen mineral soils is developed. The model is based on the dielectric measurements of three typical soils (sandy loam, silt loam, and silty clay) at the temperature range from -1°C to -30°C. The measured data as a function of moisture were fitted with the refractive mixing dielectric model. The model parameters are maximum bound water fraction, and refractive indexes of soil solid, unfrozen bound water, and wet ice. In the result of fitting measured data, the model parameters were determined as a functions of soil type (clay content), and soil temperature. The error of the predicted values of the complex relative permittivity (CRP) of frozen soils relative to the measured ones was evaluated through determination coefficients, and root mean square error (RMSE). The values of RMSE are on the order of the dielectric measurement error itself. The proposed dielectric model can be applied in active and passive remote sensing techniques used in the cold regions.

permittivity -- mineral soil -- soil moisture -- bound water -- Maxwell–Wagner effect
Аннотация: Using a generalized refractive mixture dielectric model, the influence of the relative permittivity spectra of bound and unbound water in mineral soil on the nature of the temperature dependence of the relative permittivity of natural mineral soil, with a clay fraction content of 41.3%, was studied in the electromagnetic field frequency range from 50 MHz to 15 GHz. The causes of the emergence of intersections in the relative permittivity spectra of mineral soil, obtained at different temperatures but for a sample of the same moisture content, have been studied. It has been proved that the emergence of such an intersection point in the frequency range up to 1.5 GHz is due to the Maxwell–Wagner effect in bound water. The dependences of the frequency of the intersection point of the relative permittivity spectra of mineral soil on the temperature and volumetric content of bound and unbound water have been studied.

Аннотация: A frequency spectrum of the complex dielectric permittivity of soils is measured in the range of frequencies from 0.5 to 15.0 GHz in the course of frost penetration and thawing. The phase transitions taking place during frost penetration and thawing are analyzed within the concept of the generalized refractive mixing dielectric model (GRMDM). Two types of water concurrently present in the soil are identified: bound and free water. Temperature dependences of the Debye model parameters for each type of water are given, and parameters of a dielectric spectroscopic model of frozen and thawed soils are found. The hysteresis phenomenon during the phase transition of the soil moisture is investigated.
