Peculiarities of satellite TV broadcasting on high-latitude satellite-serviced areas

A universal modeling tool is being developed on the basis of the global Upper Atmosphere Model (UAM) for studying the interrelationship of the broad range of various processes and phenomena in the upper atmosphere. For this purpose the UAM structure was reorganized into the open framework, including the controlling Metamodel Manager and several subordinate models of separate atmospheric regions and processes. They are, for example, an ionosphere model, neutral atmosphere model, electric field model, wind model etc. Each included model is independent from the others and calculates the certain set of physical parameters of the modeling object. These sub-models exchange data through the Manager using the unified interface. This approach allows the integration of a wide range of data sources of different kinds, both experimental and modeled. This work contains a detailed description of model data internal logical organization, which provides the possibility to store and to exchange various kinds of data with a full description in a standardized way.
