Central industrial region of Russia, as one of the most populated and industrialized region of the whole Russian Federation, is characterized by complicated ecological situation. In the Moscow city urban agglomeration a huge human population and industrial power is concentrated on a relatively small area. Moscow with its suburbs, therefore, is a notable source of anthropogenic perturbations of the natural environment. Due to its high consumption of heat and electrical energy, motor fuel, and relatively low albedo of urban landscape in visible solar spectrum, the city in fact is a strong and compact source of heat, deposited in the surrounding atmosphere. In addition, there are strong emissions of water vapor, carbon dioxide, soot, dust, aerosols etc., influencing local heat and radiation balance in the atmosphere. All the mentioned impacts cause strong perturbations of natural fields of the atmospheric parameters, e.g. temperature, pressure and relative humidity. As a consequence, there can be generated acoustical gravity waves, propagating upward and reaching ionospheric heights. These perturbations largely determine regional atmospheric dynamics, local climate and air mass transport in the city and the region. The complexity of the problem increases additionally due to huge variety of the sources of the acoustical gravity waves, like thermal and orographic inhomogeneities of the underlying surface. Thus, influence of the urban environment on the air mass transport has been repeatedly proved in the experiments. Studies show that the acoustical gravity waves, excited by the wave source at the source of the Earth, can indeed reach the ionosphere, provided their destruction due to the non-linear effects and further extinction take place at the heights above the main ionospheric maximum of the F2 plasma layer [1] During the propagation in the atmosphere, the most stable are the waves with periods close to the buoyancy (Brunt-Vaisala) frequency of the free vertical oscillations of stratified atmosphere. Typical frequencies of the acoustical gravity waves are lower than buoyancy frequencies at the ionospheric heights, while the velocities do not exceed the sound speed at there heights, which are from hundreds of meters up to 2 kilometers per second. [2 ]. For this reason, techniques of regional monitoring of the atmosphere, including both precision local in situ measurements and remote sensing of various atmospheric parameters, providing average estimates in areas, not covered by contact measurements, are of especial importance. Complexity of this problem is caused primarily by lack of various observation data, both satellite and meteorological. Due to that, development of combined techniques, capable for assimilation and integration of heterogeneous data, is now extremely important. The objective of the present study is development of complex approach to analysis of multi-instrumental data of regional atmospheric monitoring, including in situ airborne measurements together with remote sensing data, including radio occultation and interferometric experiments with radio navigational satellite systems.
