First mass spectrometric measurements of positive ions in the stratosphere
Three experiments were made at high latitudes by using rocketborne cryogenically pumped quadrupole mass filters. Mass spectra of positive ions at stratospheric heights were obtained between 24 and 60 km during descent portions of the rocket flights. The mass numbers of the most abundant ions detecte...

| Summary: | Three experiments were made at high latitudes by using rocketborne cryogenically pumped quadrupole mass filters. Mass spectra of positive ions at stratospheric heights were obtained between 24 and 60 km during descent portions of the rocket flights. The mass numbers of the most abundant ions detected are tabulated along with tentative identifications (19 plus or minus 2, 29 plus or minus 2, 37 plus or minus 2, 42 plus or minus 2, 55 plus or minus 2, 60 plus or minus 2, and 80 plus or minus 2 AMU). Figures indicate the fractional abundance on non-proton hydrates; number densities of the unknown reaction partner X as derived from the data, total gas density, and a theoretical CH sub(2) O profile; and a simplified reaction scheme for stratospheric positive ions at heights above 24 km. |
