Заглавие : Dielectric database of organic Arctic soils (DDOAS)
Место публикации : Earth Syst. Sci. Data. - 2020. - Vol. 12, Is. 4. - P.3481-3487. - ISSN 1866-3508 (ISSN), DOI 10.5194/essd-12-3481-2020. - ISSN 1866-3516 (eISSN)

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).

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 : A dielectric model for frozen mineral soils at a frequency of 435 MHz
Место публикации : Remote Sens. Lett. - 2021. - Vol. 12, Is. 9. - P.944-950. - ISSN 2150704X (ISSN), DOI 10.1080/2150704X.2021.1947537

Аннотация: A single frequency refractive mixing dielectric model at 435 MHz for frozen mineral soils is proposed. The model was created based on the laboratory dielectric measurements of three soil samples in the ranges of soil moisture from 0.01cm3 cm−3 to 0.42cm3 cm−3, temperature from– 30°C to– 1°C, clay content (by weight) from 9.1% to 41.3%. Coefficient of determination R2 and root mean square error (RMSE) predicted by the model and measured values for real () and imaginary () part of the complex relative permittivity (CRP) are = 0.988 (= 0.323) and = 0.987 (= 0.100). Compared to well-known spectroscopic models, this model is simpler in practical engineering use. The input parameters of the model are the volumetric soil moisture, temperature and the content of the clay fraction. The output parameters are the real and imaginary parts of the CRP. The created model may be used to develop new remote sensing retrieval algorithms of temperature, the content of unfrozen water and ice in the root zone of frozen soils for northern regions.ε 'ε ''R2ε 'RMSEε 'R2ε ''RMSEε ''

Заглавие : Dielectric Model for Thawed Mineral Soils at a Frequency of 435 MHz
Место публикации : IEEE Geosci. Remote Sens. Lett. - 2021. - Vol. 18, Is. 2. - P.222-225. - ISSN 1545-598X (ISSN), DOI 10.1109/LGRS.2020.2972559. - ISSN 1558-0571 (eISSN)

Аннотация: A single-frequency dielectric model at 435 MHz for mineral soils is proposed. The dielectric model was created on the basis of the laboratory dielectric measurements of three soil samples with clay content in the range of 9.1%-41.3%. The input parameters of the dielectric model are volumetric soil moisture and clay content. The output parameter of the dielectric model is complex permittivity (CP). The model prediction errors are comparable with the errors of instrumental measurements of the CP for refractive index and normalized attenuation 0.1-0.3 and 0.06-0.12, respectively, in terms of root-mean-square error (RMSE). The comparative analysis of dielectric predictions in the case of the developed model proved to obtain a better accuracy than the existing dielectric models. The created model may be recommended for practical use in the algorithms of soil-moisture retrieval in the P-band.

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.

Заглавие : Generalized refractive mixing dielectric model of moist soils considering ionic relaxation of soil water
Место публикации : Rus. Phys. J. - 2013. - Vol. 56, Is. 3. - P.319-324. - DOI 10.1007/s11182-013-0034-4
Аннотация: A generalized multi-relaxation refractive mixing dielectric model of moist soils is suggested for frequencies in the range from 0.2 to 14.8 GHz. The model is based on dielectric measurements in this frequency range at a temperature of 20A degrees D for relative moisture content (by weight) changing from 2 to 43%. The model expands the range of applicability of the single-relaxation model suggested previously to the megahertz frequency range with allowance for the Maxwell-Wagner ionic relaxation which is clearly manifested in this frequency range for bound soil water. It is demonstrated that the error in calculating the complex dielectric permittivity spectra of the moist soil has the same order of magnitude as the error of experimental data used for model construction.
