Novomoskovsk is one of the main centers of chemical industry in central Russia. In 2000 to control and monitor the region air quality and movement the atmosphere ecomonitorin system was created. These systems’ modifying lies in using more sophisticated technology, increasing number of observation stations and automatic sensors that determine harmful impurities. The data adequacy of airspace’s state hinges on the number of these stations and their location. The objective of our study is to estimate the data adequacy relying on modern research methods. The research involved the interpolation method of air movement control over areas which have a mixed landscape because of technology-related accidents. The method consists of 3 main stages: experimental examination of the area’s weather conditions, processing of this data using the method of air flow field recovery, and effective control of the air dynamics at man-made accidents. Air control stations gave the initial measures and current data to develop the method of air flow field recovery on the basis of the noise-resistant interpolation principle. Noise-resistant interpolation admits to errors of measuring instruments, which makes a significant magnitude when estimating meteorological data of the air. The data obtained requires to modify Novomoskovsk ecomonitoring system of the atmosphere.
