Potentialities of the atmospheric research on the base of solar spectroscopy techniques are discussed. Methods of the solar spectroscopy have some important advantages due to the possibility of the simultaneous measurements of many gases, their inexpensivety and safety to ecology, etc. From 1991 the Earth atmosphere investigations are pursued on the base of the horizontal solar telescope with the Echelle spectrograph in the Kyiv University Astronomical Observatory. It was found that in the air basin of Kyiv the NO2 content is about 3 multiplied by 10-8. Minimum concentration of NO2 was observed at the beginning of the year and maximum ones -- in summer and autumn. It is possible that the NO2 concentration was considerably higher in 1981, when the level of the solar activity was very high. It has been also determined that the oxygen content above Kyiv was unchanged during last 15 years.
