Thirteen ozone soundings with Mast instruments and fifteen Umkehr measurements were obtained during 1968. A model for the vertical distribution of ozone is described. A procedure for and the results of fitting this model to our soundings, and to mean soundings at other locations, is described. A procedure for comparing balloon measurements and simultaneous Umkehr measurements is also outlined. The essential point in this procedure is to compute Umkehr curves from the balloon measurements, rather than vice versa. A stratospheric model employing quasi-geostrophic dynamics and simplified terms representing radiative-photochemical effects is presented. The spectral method is used for solution. The model is integrated for 230 days from an initial state of radiative-photochemical equilibrium. A redistribution of ozone similar to the observed one is outlined, accomplished largely by large-scale quasi-horizontal eddies. The energy cycle is studied in detail and the study reveals the overwhelming importance of energy supplied to the stratosphere from the troposphere. Author
