SODAR study of the boundary layer over moscow for air-pollution application

The 24-hour SODAR measurements of the atmospheric boundary-layer parameters over Moscow were carried out during one month in the summer of 1990 and one month in the winter of 1991 at three points within the city and suburbs. The simultaneous measurements of the concentrations of several pollutants were also carried out at one of these points. The relations between local concentrations of some pollutants and the parameters measured by SODAR (mixing height and wind speed) are revealed. This fact confirms the usefulness of SODAR observations for air-pollution meteorology. The statistics of the boundary-layer parameters in summer and winter seasons as well as the data on their spatial variations over the city were obtained.
