[The use of remote probing methods to evaluate ambient air pollution]

The results of field measurements made at four stationary atmosphere observation posts located within the dwelling area of a large industrial town and remote probing data obtained from a LANDSAT satellite having an ETM sensor (Enhanced Thematic Mapper) and from a Terra satellite having ASTER sensory techniques were comparatively characterized. Based on the developed signatures (measurement standards), the authors drew up technogenic ambient air pollution maps by principal components. The findings and the data obtained by using other technologies, such as simulation of the diffusion of pollutants in the atmosphere by the maximum single and mean annual concentrations; assessment of the risk to human health, permitted a comprehensive assessment of the situation and were used to develop managerial decisions aimed at stabilizing the environmental sanitary situation in the region under study.
