T1 RADAR IDENTIFICATION OF DESERT REGIONS AS SUPPLIERS OF DUST IN THE ATMOSPHERE JF Telecommunications and Radio Engineering JO TRE YR 2016 FD 2016-08-16 VO 75 IS 10 SP 937 OP 948 K1 radar observations K1 highly directional radio wave backscattering K1 the Aeolian transport of sand and dust K1 sand ripples K1 ionization K1 electric field AB Atmosphere dust represents a mixture of minute particles of various salts and minerals. Also it contains remains of animal and vegetable organisms, spores of causative organisms and so forth. The dust is carried by winds over considerable distances and its presence in the atmosphere is among the factors which have an essential influence on the global climate of the Earth. At present the aeolian processes and their consequences are monitored from space using multispectral optical systems (TOMS, METEOSAT, MODIS etc.) only. These are not capable of reliable identification of the areas themselves that are sources of raising the dust in the atmosphere independently of the cloudiness, solar illumination and transparency of the atmosphere. This problem can be solved with the use of space radar systems of the Earth remote sensing [1]. The paper presents the first results of the development of a radar technique of identification of desert regions in which dust from the surface is transported up to the atmosphere under the action of the Aeolian processes. The work was performed using data of Earth remote sensing SAR Envisat-1 obtained over deserts of Mauritania. Specific features of display of the narrow-beam backscattering of radio waves in radar images in dependence on the surface wind speed and direction and direction of radar illumination of the surface. It is concluded that the radar means of remote sensing represent an efficient tool for detecting regions of dust raise into the atmosphere. Results of the study can be used for the development of new methods of remote monitoring of the processes in desert areas that affect the climate of vast regions of the Earth.
