The Methodology for Assessing and Diagnosing the Spatial-Temporal Variability of Ground-Level Atmospheric Pollution in Areas with Increased Environmental Stress

Abstract

The aim is to develop a methodology for assessing the spread of harmful impurities in the area of the airfield of state aviation and its application to assess the spatial and temporal variability of the concentration of harmful impurities. Materials and methods. A technique has been developed to assess and predict points with increased concentrations of harmful impurities on the territory of an airfield in conditions of increased aviation flight intensity. Results and discussion. Based on numerical and field experiments, this method was tested at the Baltimor State Aviation Airfi eld. The experiments were conducted in dry weather during the summer and autumn of 2021-2023. Meteorological parameters were measured using a small-sized automatic meteorological station (MAMS) and an AMG-510 gas analyzer. Conclusions. According to the proposed methodology, it is possible to predict the pollution of the surface layer of the atmosphere with harmful impurities under various meteorological conditions and the intensity of operation of the state aviation airfi eld, taking into account the geographical and climatic features of its location, topography, locations of build ings and structures, and their geometric dimensions. Knowing the exact nature of the distribution of harmful impurities, it is possible to eff ectively plan measures for monitoring and reducing air pollution at the airfi eld, as well as preserving the health of personnel working at the airfield.
