Capabilities for planning and managing normalization processes in urban airspace areas

Abstract

Abstract The article discusses the possibilities of planning and managing processes of normalization of urban airspace using the example of pollution with nitrogen oxides and PM2.5 particles. An assessment of the level of air pollution in a large city using the example of Kyiv revealed a significant amount of nitrogen oxides along the main roads, and even the presence of green spaces does not save the situation. Due to differences in access to fresh air, different areas of the city develop their own microclimates with elevated temperatures and pollutant content. Such “hot areas” must be identified and declared hazardous to human habitation. It is noted that the largest amount of air is required to dilute the exhaust gases of diesel cars, where there is a large emission of soot, and carburetor cars, where there is a large emission of carbon monoxide. For almost all types of transport, the presence of nitrogen oxides is observed in emissions, which require a significantly larger amount of atmospheric air for dilution, with a difference of two times and an order of magnitude compared to carbon oxides and soot. Green spaces must occupy large areas to have a significant impact on the environment. Improving ecosystem services for air purification and climate regulation requires not only planning urban green spaces as a comprehensive solution, but also special air purification devices.
