The problems of relevance of creating a regional information system of environmental monitoring and protection are considered. Scientific bases of multilevel information system of monitoring are developed taking into account some peculiarities of Rostov region. The integral approach is used? The choice of mathematical models is substantiated and calculation modules for each level of the regional information system of monitoring are defined, the atmospheric protection for calculation of concentration of the main near-Earth pollutants is offered. The data bank and control optimization system are created. Additional information on experimental studies is being collected, which is necessary to assess the adequacy of the program complex in the conditions of the Rostov region.
