AbstractVertical profiles of ozone have been measured at balloon altitudes. Our purpose is to examine the character of vertical wavenumber spectra of ozone fluctuations, to assess the possible roles of gravity wave field in ozone fluctuations, and to determine dominant vertical wavelengths of ozone spectra. Vertical wavenumber spectra of 12 ozone fluctuations obtained during June-August 2003 are presented. Results indicate that mean spectral slopes in the wavenumber range from 4.69 x 10(-4) to 2.50 x 10(-3) cyc/m are about -2.91 in the troposphere and -2.87 in the lower stratosphere, which is close to the slope of -3 predicted by current gravity wave saturation models. The consistency of the observed spectral slopes with the value of -3 predicted by current gravity wave saturation models suggests that the observed ozone fluctuations are due primarily to atmospheric gravity waves. At m = 1/(1000 m) the mean spectral amplitude is over 30 times larger in the lower stratosphere than in the troposphere. Mean vertical wavenumber spectra in area-preserving form reveal dominant vertical wavelengths of similar to 2.6 km in the troposphere and similar to 2.7 km in the lower stratosphere, which is consistent with the values varying between 1.5 and 3.0 km estimated from the velocity field and temperature field at these heights.
