Abstract >>
The article is about the pioneer atmospheric-optical space researches and conservative systems of remote sensing of the near-earth space on the basis of the Earth radiation characteristics. Space researches are such area of fundamental and applied works, which from the first steps of the formation could not develop without the use of computers. Space exploration was a significant factor in the improvement of the computers and the formation of new scientific trends connected with mathematical modeling of the Earth radiation field, the theory of image transfer, theory of vision, theory of processing and recognition of images, etc. Information and mathematical software is an indispensable part of any space project. The short history of the nuclear and space projects and formation of scientific schools on the theory of radiation transfer is presented to restore the true facts of the beginning of opening of the space era and development of the cosmonautics. Our goal is to show as the ingenious Chief theoretician-mathematician V.M. Keldysh and Chief engineer-constructor S.P. Korolev together conquered space. It is important to pay attention to the prospective scientific directions connected with the application of computer science" with parallel supercalculations, GRID and cloudy" technologies in varied space researches, the problems of the Earth remote sensing, the evolution of environment, and climate of the Earth.

Institute of Physical Material Science of the Siberian Branch of the RAS, 670047, Ulan-Ude, 8, Sakhyanovoy str
Keywords: microwave sensing, brightness temperature, soil moisture, layered soil

Abstract >>
The angular and polarization dependencies of the brightness temperature measured by the spaceborne radiometer SMOS in L-band on different parts of the earth's surface are shown. It is found that in some cases the results are not described by the existing model for the reflection coefficient of microwaves, which leads to errors in recovering the soil moisture. It is shown by calculation that the layered structure of soil moisture has a significant impact on the behavior of brightness temperature. It is proposed to expand the moisture-recovering algorithm by the method which takes into account possible layered structure of the soil moisture.

The technique of space infrared and microwave atmospheric sounding with ATOVS instrument is discussed. The results of the sounding are vertical profiles of atmosphere. Zenith tropospheric delay was estimated with the profiles and with the Saastamoinen and Hopfield delay models using surface measurements. Biases of the model-derived estimations are -0,0186 m for the Saastamoinen model and -0,0135 m for the Hopfield one during the whole 2012. The results are valid for Krasnoyarsk (middle latitudes of Siberia).

Aerosol optical thickness and aerosol index variations caused by large-scale forest fires in Central Yakutia in 2002 were studied by remote sensing data (NOAA, Terra, Earth Probe). Total emissions of CO2, CO, CH4 etc. were calculated using modeling approach and MODIS/Terra burned area data. A comparison of total emissions from forest fires in Central Yakutia with global fire and volcanic emissions are made. Long-range transport events of aerosol particles during maximum activity of forest fires are examined.

Abstract >>
The main directions of the ecological control of the territory from the space are the development of methods of remote sensing of the parameters of Earth surface and atmosphere and monitoring of the state of the environment. Monitoring data are necessary for investigation of natural processes and analysis of impacts of natural and anthropogenic factors on the natural environment. For receiving, processing, and analysis of data of the satellite remote monitoring, it is necessary to create appropriate software. The article considers a program-analytical complex based on MODIS satellite data allowing counting vegetation indexes and analysis of their behavior. On the basis of statistical data, the dependence of natural variations in the indexes is determined that allows detecting changes in the variations due to anthropogenic impacts.
