| Abstract: | Atmospheric composition in the turbopause regime was determined by four rocket-borne mass spectrometers, which employed shock-freezing cryo-ion sources. Number densities of N2, O2, O, Ar and CO2 are presented for these experiments. The results are compared with those of other rocket experiments taken from the literature. Ar/N2 ratios are analyzed with respect to atmospheric turbulence. Magnitude and variability of atomic oxygen layer maximum density and layer content are discussed. Variations of O densities and simultaneous Ar/N2 ratio changes are compared. Six CO2 measurements are discussed in terms of CO2/N2 ratios. |
