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.

Аннотация: A single-frequency dielectric model for thawed and frozen Arctic organic-rich (80%-90% organic matter) soil was developed. The model is based on soil dielectric data that were measured over the ranges of volumetric moisture from 0.007 to 0.573 cm3/cm3, dry soil density from 0.564 to 0.666 g/cm3, and temperature from 25°C to -30°C (cooling run), at the frequency of 1.4 GHz. The refractive mixing model was applied to fit the measurements of the soil's complex refractive index (CRI) as a function of soil moisture, with the values of temperature being fixed. Using the results of this fitting, the parameters of the refractive mixing model were derived as a function of temperature. These parameters involve the CRIs of soil solids as well as bound, transient, and free soil water components. 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 = 0.999, RMSE = 0.27 and R2 = 0.993, RMSE = 0.18 for the real and imaginary parts of the CRP, respectively. These values are in 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 areas with organicrich soil covers, mainly for the SMOS, SMAP, and Aquarius missions.

Аннотация: We made the conclusion about the main deficiencies of the SMOS data Level 1c and Level 2 for the south part of Western Siberia. This was done for the period from 12.07.10 to 10.11.11 by studying SMOS data, periodic ground base measurements of the brightness temperature at 1.4 GHz and ground base measurements of moisture. We developed a simple algorithm for remote retrieval of soil moisture using data of brightness temperature given at SMOS Level 1c, compared the data of soil moisture, given at SMOS Level 2 with data calculated by our algorithm and in situ measurements of moisture.

Заглавие : Experimental analysis and empirical model of the complex permittivity of five organic soils at 1.4 GHz in the temperature range from −30 °C to 25 °C
Место публикации : IEEE Trans. Geosci. Remote Sensing. - 2019. - Vol. 51, Is. 6. - P.3778 - 3787. - ISSN 0196-2892, DOI 10.1109/TGRS.2018.2887117

Аннотация: The dielectric measurements were made for five organic soils taken from the tundra territories of Alaska, Yamal, and Taimyr, with the content of organic matter varying from 35% to 80%. The measurements were carried out in the temperature range from −30 °C to 25 °C, frequencies from 0.45 to 16 GHz and soil moisture from close to zero to the field moisture capacity. The refractive mixing model was applied to fit the measurements of the soil’s complex refractive index (CRI) as a function of soil moisture, with the values of temperature being fixed. As a result, a respective dielectric model was developed. The amounts of bound and transient water in the thawed and frozen soils were introduced as parameters of the developed model and derived as a function of temperature and content of soil organic matter. The other parameters which concern the CRIs of soil solids as well as bound, transient, and liquid soil water or ice components were derived as a function of temperature. The errors of the proposed model estimated in terms of the values of normalized root-mean-sqaure error for the real and imaginary parts of the soil complex relative permittivity appeared to be 6%–7% and 23%, respectively. The proposed dielectric model can be applied in active and passive remote sensing, in particular, for the SMOS, SMAP, and Aquarius missions after testing in ground-based experiments.

Заглавие : Dielectric model of thawed and frozen organic soil at the AMSR radiometer frequency
Место публикации : Izv. Atmos. Ocean Phys. - 2021. - Vol. 57, Is. 12. - P.1783-1788. - ISSN 00014338 (ISSN), DOI 10.1134/S0001433821120318

Аннотация: In this paper, we develop a simple single-frequency dielectric model of thawed and frozen arctic soil for a frequency of 6.9 GHz. The model is developed based on laboratory dielectric measurements of soil samples containing 80–90% organic matter in the range of gravimetric moisture from 0.01 to 0.942 g/g (volumetric moisture ranging from 0.007 to 0.573 cm3/cm3), and temperatures from +25 to –30°C in the freeze mode. A refractive mixture model is used as a regression equation for the measured values of the complex soil refractive index depending on moisture. The complex refractive indices of various soil components (mineral-organic , bound, transitional, and free water (ice for frozen soil)), as well as values for the maximum allowable content of bound and transitional water in the soil at all measured temperatures, are determined using the regression analysis. The empirical dependences of the complex refractive index of soil components and the maximal allowable contents of various types of water in soil on temperature are obtained. As a result, we developed a model that allows calculating the permittivity of thawed and frozen organic soil as a function of moisture and temperature at 6.9 GHz. The root-mean-square error was 0.20 for the real part of the complex dielectric permittivity of the soil and 0.22 for the imaginary part at the determination coefficient values of 0.999 and 0.995, respectively.

Аннотация: The studies were designed to ensure correct inclusion of profiles into our model. These promising results will be followed by a validation stage. To do that, we have experimental data sets. We have moisture measurements (with the presence of gradients) and emissivities from the site of SMOSREX (nearly no temperature gradients). On the other hand, we have measurements of high temperature gradients, moisture, emissivity and bi static scattering coefficients from a measurement site in Siberia [8].

Заглавие : Numerical computation of the L-band emission and scattering of soil layers with consideration of moisture and temperature gradients
Коллективы : IEEE International Geoscience and Remote Sensing Symposium (2012 ; July ; 22-27; Munich, Germany)
Место публикации : IEEE International Geoscience and Remote Sensing Symposium (IGRASS): Proceedings. - Munich, 2012. - P.20-23. - ISBN 978-1-4673-1159-5, DOI 10.1109/IGARSS.2012.6352444
Аннотация: In the context of the Soil Moisture and Ocean Salinity mission, we present a study of the emission of rough surfaces at 1.4 GHz and the effects of moisture and temperature gradients. A new approach for the calculation of rough surface scattering and emission at L-band has been validated for the case of scattering from rough surfaces of Gaussian autocorrelation function. This approach relies on the use of ANSYS's numerical computation software HFSS, which in turn solves Maxwell's equations using the Finite Element Method. The interest of this approach is that it can be extended to calculate the emission and scattering of complicated multilayer media. In this paper we present the work we done to use FEM method to compute thermal effects and water infiltration effects in ground. We firstly present the effects of water infiltration in ground then we present results of computations on soils partially or completely frozen.

Заглавие : Temperature and texture dependent dielectric model of MOIST soils at the SMOS frequency
Коллективы : IEEE International Geoscience and Remote Sensing Symposium (2012 ; July ; 22-27; Munich, Germany)
Место публикации : IEEE International Geoscience and Remote Sensing Symposium (IGRASS): Proceedings. - Munich, 2012. - P.1127-1129. - ISBN 978-1-4673-1159-5, DOI 10.1109/IGARSS.2012.6351350
Аннотация: In this paper a single-frequent temperature and texture dependent dielectric model for moist soils is proposed. This model is designed for the frequency of 1.4 GHz at which the European sensor SMOS operates to monitor moisture of the Earth surface from space. Earlier, the dielectric model was created, that provides estimations of the complex dielectric constant of moist soils as a function of frequency, temperature, moisture and mineralogy of soils. This model was developed based on extensive measurements of the dielectric constant for a wide ensemble of soils (clay content from 0 to 76%), moistures (from zero to molecular moisture capacity), temperatures (10° C to 40° C), and frequencies (0.3 to 26.5 GHz). This model provides for fairly good accuracy. But, being cumbersome to account for frequency dependencies, the model is not always convenient for practical use at a single frequency. Exclusion of the frequency dependence allowed us to obtain a substantially more simple dielectric model to estimate the complex dielectric constant of soil at a single frequency of 1.4 GHz as a function of moisture, temperature, and clay content.

Аннотация: In this study we investigated correlations between soil temperature and radar backscattering coefficient (HH-pol) measured by the ALOS PALSAR at the frequency of 1.26 GHz, and brightness temperatures measured by SMOS/MIRAS (viewing angle 55°, V-pol) at the same frequency and GCOM-W1/AMSR2 (V-pol) in the range of frequencies from 6.9 GHz to 18.7 GHz near Vaskiny Dachi weather station (70.2955N, 68.8835E) over the territory of the Yamal Peninsula. Empirical relationships between brightness temperature, backscattering coefficient and soil temperature have been found, which allow to predict the soil surface temperature on the test site from GCOM-W1 and ALOS PALSAR measurements.

Заглавие : Temperature dependent dielectric model at 1.4 GHz for a tundra organic-rich soil thawed and frozen
Коллективы : Geoscience and Remote Sensing Symposium
Место публикации : Geoscience and Remote Sensing Symposium (IGARSS), 2015 IEEE International. - 2015. - P.2016-2019. - DOI 10.1109/IGARSS.2015.7326194
Аннотация: A mono-frequency dielectric model for a tundra organic-rich soil both thawed and frozen has been developed. The model is based on the soil dielectric measurements carried out in the ranges of volumetric moisture from 0.007 to 0.573 cm3/cm3, dry soil density from 0.564 to 0.666 g/cm3, and temperature from 25 to −30 °C (cooling run), at the frequency of 1.4 GHz used by the SMOS instrument. To fit the results of measurements of the soil complex refractive index (CRI) as a function of soil moisture, the refractive mixing model was applied. As a result, the parameters of the refractive mixing model linked to soil solids, as well as the bound, transient, and free soil water components were derived as a function of temperature. The error of the proposed dielectric model was shown to be in the order of the dielectric measurement error itself1.

Ключевые слова (''Своб.индексиров.''): frozen mineral soils--dielectric measurements--dielectric model--unfrozen bound water--moistened ice--1.4 ghz
Аннотация: A single-frequency dielectric model at 1.4 GHz for frozen mineral soils was developed, with the temperature and gravimetric clay content varying from − 1 to − 30°C and from 9.1 to 41.3%, respectively. The model is based on the refractive mixing dielectric model and the dielectric data measured for the three typical soils collected in the Yamal tundra. The refractive mixing dielectric model was applied to fit the measured dielectric data as a function of soil moisture at a number of fixed temperatures. As a result, the parameters of the developed model were derived as a function of temperature and texture. This set of parameters consists of the maximum gravimetric fraction of unfrozen bound water and the values of the complex refractive indexes relating to soil solids, unfrozen bound water, and moistened ice. The developed model for frozen mineral soils in conjunction with the previously developed by us dielectric model for thawed mineral soils is considered as an integral dielectric model which is applicable for permittivity calculations of soil in both thawed and frozen states. The developed integral dielectric model for frozen and thawed mineral soils was validated using the dielectric data for five measured soils, and the statistical errors were estimated in terms of the root mean square error and the determination coefficient. In addition, the only known in the literature dielectric model for frozen soils suggested by Zhang was validated based on dielectric data for soils measured in this research. The comparative analysis proved substantially better accuracy of predictions in the case of the developed model as compared to those related to the Zhang model.

Заглавие : Temperature- and texture-dependent dielectric model for moist soils at 1.4 GHz
Место публикации : Geosci. and Remote Sensing Lett., IEEE. - 2013. - Vol. 10, Is. 3. - P.419 - 423. - DOI 10.1109/LGRS.2012.2207878
Аннотация: In this letter, a monofrequent dielectric model for moist soils taking into account dependences on the temperature and texture is proposed, in the case of an electromagnetic frequency equal to 1.4 GHz. The proposed model is deduced from a more general model proposed by Mironov and Fomin (2009) that provides estimations of the complex relative permittivity (CRP) of moist soils as a function of frequency, temperature, moisture, and texture of soils. The latter employs the physical laws of Debye and Clausius-Mossotti and the law of ion conductance to calculate the CRP of water solutions in the soil. The parameters of the respective physical laws were determined by using the CRPs of moist soils measured by Curtis (1995) for a wide ensemble of soil textures (clay content from 0% to 76%), moistures (from drying at 105 °C to nearly saturation), temperatures (10 °C -40 °C), and frequencies (0.3-26.5 GHz). This model has standard deviations of calculated CRPs from the measured values equal to 1.9 and 1.3 for the real and imaginary parts of CRP, respectively. In the model proposed in this letter, the respective standard deviations were decreased to the values of 0.87 and 0.26. In addition, the equations to calculate the complex dielectric permittivity as a function of moisture, temperature, and texture were represented in a simple form of the refractive mixing dielectric model, which is commonly used in the algorithms of radiometric and radar remote sensing to retrieve moisture in the soil.

Аннотация: Проведены диэлектрические измерения пяти образцов органических почв с различным содержанием органического вещества в диапазоне температур от -30 до 25 °С в широком диапазоне частот от 0.45 до 16 ГГц. На их основе создана простая одночастотная диэлектрическая модель талых и мерзлых органических почв, позволяющая рассчитывать комплексную диэлектрическую проницаемость талых и мерзлых органических почв в зависимости от влажности, температуры и содержания органического вещества на частоте 1.4 ГГц.Dielectric measurements were conducted for five organic soil samples with different contents of organic matter in the temperature range from -30 to 25 °C over a wide frequency range from 0.45 to 16 GHz. On this basis, a simple single-frequency dielectric model for thawed and frozen organic soils was created. The model allows to calculate the complex dielectric constant of thawed and frozen organic soils depending on the moisture, temperature, and organic matter content at a frequency of 1.4 GHz.
