Observations of the Atmosphere Composition in the Moscow Megapolis from a Mobile Laboratory

摘要

Results of unique experimental observations of the atmospheric composition over the Moscow megapolis carried out using a mobile railroad laboratory are presented. The surface concentrations of key gas components and aerosol, and the radiative and meteorological parameters were measured. Distributions of admixtures and atmospheric parameters in the radial section of the megapolis and along its perimeter were obtained for the first time. Data analysis reveals the sources of pollution, character, and degree of the influence of the city on the regional atmosphere.
