SODAR STUDY OF THE BOUNDARY-LAYER OVER MOSCOW FOR AIR-POLLUTION APPLICATION

The 24-hour SODAR measurements of the atmospheric boundary-layer param eters over Moscow were carried out during one month in the summer of 1 990 and one month in the winter of 1991 at three points within the cit y and suburbs. The simultaneous measurements of the concentrations of several pollutants were also carried out at one of these points. The r elations between local concentrations of some pollutants and the param eters measured by SODAR (mixing height and wind speed) are revealed. T his fact confirms the usefulness of SODAR observations for air-polluti on meteorology. The statistics of the boundary-layer parameters in sum mer and winter seasons as well as the data on their spatial variations over the city were obtained.
