When constructing a system for routine monitoring of the ecological state of the environment, one faces the problem on transmitting the data acquired, besides the problem of obtaining reliable information that is not redundant. Besides, the use of different, by types of measurements and the information acquired, information sources requires different channels to be used for data transmission, formats of transmitted data and methods of data transmission under regular and emergency conditions. In this paper we evaluate the information streams circulating in one of the systems developed at the Institute of Atmospheric Optics SB RAS (the routine monitoring system “Gorod”). This system combines two principles of constructing such systems, that is, the spatially representative one and that oriented toward data sources. This is achieved by employing the network of observation stations available and by introducing lidars to that system structure. In addition to the lidar measurements, a wide-aperture photometer is used for reconstruction of the pollution pattern over the region surveyed.
The data formats and the order of data transmission under regular and emergency conditions are determined for various data sources. Recommendations are given on how to deploy the information sources and on the arrangement of communication with these sources.
