THE ACTIVE LAYER OF THE ARCTIC TUNDRA SOILS TEMPERATURE SOUNDING ON THE BASIS OF L-BAND RADIOMETRIC OBSERVATIONS
Аннотация
Possibility of remote sounding of temperature in the frozen active layer on the North Slope of Alaska was investigated with the use of SK SMOS microwave radiometer on a frequency of 1,4 GHz. It is shown that the soil temperature, sounded with the SMOS, with an error of 2,4 ˚C coincides with the average temperature of the soil in a layer of 0,27 m.

ESTIMATION OF SNOW WATER EQUIVALENT BY USE OF SATELLITE RADIOMETRY FOR THE STEPPE ZONE OF WESTERN SIBERIA
Аннотация
In the work the authors present the results of validation of algorithms of restoration of snow water equivalent for steppe regions of Western Siberia. Microwave data from AMSU-A and AMSR-E radiometers installed on the satellite NOAA and Aqua platforms were a source of basic data. It is shown that for two-frequency algorithms, the correlation coefficient between the real and restored values of moisture content changes from 0,06 to 0,5 at average value 0,3. The statistical importance of the received estimates is insignificant and corresponds to a case of strong spatial averaging (about 50 km in pixel) that also reduces a value of results. It is shown that almost applicable accuracy (it is better 40 %) is reached at considerable averaging - more than 40 points. It corresponds to temporary averaging to level of average monthly indicators or to spatial averaging on an element of 280x280 sq. km.

DEPENDENCE OF BRIGHTNESS TEMPERATURE SOUNDED WITH SPACECRAFT SMOS ON THE AZIMUTH ANGLE OF SOUNDING
Аннотация
The results of the analysis of angular dependence of soil brightness temperature obtained in the natural, model experiment, and with SMOS satellite, are presented. It is found that the value of surfaces brightness temperature with periodic profile considerably depends on the azimuth angle of sounding. Such surfaces under certain conditions can have a value of brightness temperature greater on the horizontal polarization than on the vertical polarization. Similar correlations are often observed in the SMOS data. It is shown that the features of the angular dependence of brightness temperature obtained by SMOS can be explained both by natural processes and hardware errors. The results can be used in the SMOS data processing.

FEATURES OF THE BRIGHTNESS CHARACTERISTICS OF THE SOUTH OF WESTERN SIBERIA AND NORTHERN KAZAKHSTAN DURING SNOW ABLATION MEASURED BY SMOS-SATELLITE
Аннотация
Results of the analysis of brightness characteristics of soil during freezing/thawing process and frozen state are presented. It is found that the brightness temperature measured by MIRAS radiometer of the SMOS-satellite, changes only slightly during the soil freezing due to the climatic and geographical features of the south of Western Siberia. It is shown that satellite data like ground measurements poorly correlate with the parameters characterizing the state of the soil while it is in the frozen state. The effect of azimuth survey regarding from the meridional direction at the time evolution of brightness temperature during snow thawing was observed. Founded dependences should be taken into an account in the processing and use of the SMOS satellite radiometric data.

CHANGES OF THE BOUND WATER DIELECTRIC PROPERTIES IN SOILS AT INCREASE OF ITS QUANTITY
Аннотация
The measurements of the complex dielectric constant (CDC) of soils with low water content at the frequencies 1 MHz — 4 GHz are performed. It is shown that the CDC of bound water at frequencies below 1—1.5 GHz depends on it’s quantity in the soil. A model of the frequency and moisture dependence, including three frequency areas of relaxation, is created. It is shown that account of the dependence of CDC of bound water on its quantity can significantly improve the accuracy of the refractive soil models at low moisture. It is revealed that in soils with large clay content at frequencies below 20 MHz deviations from monotonic bound water CDC dependence on moisture are observed. The results can be used for improving the accuracy of soil moisture remote determination by microwave methods.

EFFECT OF SOIL ORGANIC MATTER ON THE DIELECTRIC PERMITTIVITY AT THE FREQUENCIES 10 kHz - 8.5 GHz
Аннотация
The results of measurements of the soils dielectric constant with different amounts of clay and organic matter (humus) are presented. It is shown that the growth of humus and the clay content increases the maximum amount of bound water. At frequencies above 1 GHz this leads to a decrease in the soil dielectric constant at high moistures. At frequencies 10-100 MHz the presence of clay leads to an increase of the soil dielectric constant, and the presence of humus leads to its reduction. It is also shown that the dielectric constant of transitional water depends on the frequency and increases rapidly at frequencies below 100 MHz. The results can be used to construct models of dielectric soil.

METHODS OF EXPERIMENTAL DETERMINATION OF PARAMETERS OF THE INEQUALITIES OF THE SOIL COVER
Аннотация
The hardware-software complex which allows to define, with the minimum expenses, the spatial distribution and statistical characteristics of parameters of a micro relief of the spreading surface is described in the article. The micro relief in this case is understood as inequalities with the size from units of millimeters to units of decimeters. The size of a studied site of a surface is defined by the sizes of the laboratory stand and is limited to the first ten square meters. The horizontal and vertical extent of not uniformity of the micro relief can be defined: average value, dispersion, distribution by the sizes - its look and quantity of fashions. Creation of CMR in studied scale is also possible. The express determination of the sizes is made within model of the two-dimensional casual process which correlation function is calculated with the use of the theorem of Wiener-Hinchina. For the assessment of distribution by the sizes the algorithm of disconnection of contours is used. Creation of digital model of a micro relief proceeds with the use of stereo photos.

DETERMINATION OF SOIL MOISTURE USING POLARIZATION REFLECTOGRAM OF GLONASSAND GPS-SIGNALS
Аннотация
The authors present the received interference reflectograms of soil in natural conditions with the use of registration of the signals of radiation of the constellations of navigation satellites GLONASS and GPS by receiving aerials with different polarizing characteristics. The algorithm of restoration of humidity (wet) in the surface soil layer and its geometry is designed and evaluated on the basis of the use of spatial selection and the statistical processingof time dependences of the reflectograms. The generalized refractive dielectric model for wet soils was used. It is shown that the use of dipole aerials in the method of interferential reflectometry is more efficient for reconditioning of the soils moisture.
