The results of long-term measurements of total ozone (TO) obtained during 1979-2001 over Tien Shan at the Issyk Ku! (1K) station have been analyzed by the Fourier transform and the wave!et method. The results of the spectral analysis for TO were compared with similar results for the ground surface temperatures. It has been found that the variability of the surface temperature behavior correlates with the TO variations. To study the temperature spectral harmonics variations with altitude the NCERINCAR data on temperature vertical distributions were used. It was found that within the range of 850-10 mb the temperature spectra behaved differently mainly at the heights less than those of the surrounding mountains (500 mb), below the polar tropopause ('-25O mbar) and between the polar and tropical tropopauses. The peculiarities of TO harmonics for the periods from 15 to 45 months are in higher correlation with the temperature spectral harmonics up to levels of 100-50 mbar (over the tropical tropopause).

Results of regular long-term spectroscopic measurements of carbon dioxide and water vapor in the atmosphere over the Issyk Kul station (42° 37' N, 79° 59' E, 1650 m above the sea level) during 1980 -1997 are discussed. The technique of spectroscopic measurements used is based on recording spectra of solar radiation passed through the atmosphere. Recorded were the spectrum portions within the CO2 4v2 + v3 absorption band at 2.O6. Analysis of the spectrograms recorded within this interval, including the wings of this absorption band, enabled us to reconstruct both the carbon dioxide and water vapor content in the atmosphere.

We present here some measurement results on the atmospheric methane column density obtained, in Zvenigorod in September 1997. The measurements have been carried out in parallel using several variants ofthe spectroscopic method and instrumentation. Thus obtained results showed that three different modifications of the method and measurement instrumentation that are normally used in long-term observations in different observation sites yield, when operated in one site, the data that agree quite well.
