      abstract     = {This paper reanalyzes the measurements of the D content in
                      tropospheric water vapor by Ehhalt ( 1974) correcting for
                      the isotopic contamination by wall water in the sampling
                      tubes. The resulting corrections decrease the original D
                      content. They are small for the data from the flights
                      through 1967, which extended from the surface to 9 km
                      altitude, but are large for the flights beginning 1971,
                      which ranged from 6 to 13 km altitude and collected smaller
                      amounts of water vapor. No correction therefore was
                      attempted for the latter. The corrected data of the earlier
                      flights are presented in the form of seasonally averaged
                      profiles over Scotts Bluff, Nebraska; Death Valley,
                      California; and the Pacific offshore of San Luis Obispo,
                      California. As to be expected, the vertical profiles from
                      the earlier flights show a decrease in the D content with
                      altitude and a seasonal variation at all altitudes. However,
                      when plotted against the water vapor mixing ratio, the D
                      data from all seasons collapse on a line which closely
                      follows that given by Rayleigh condensation with a
                      fractionation factor alpha = 1.1, constant with altitude.
                      These data can be explained by a simple one-dimensional
                      convection model and the assumption that condensed water is
                      lofted along with the water vapor.},
