The instrumentation, interpretation procedure, and some examples of ozone profile retrieval in space experiments with the Priroda module of the Mir space station are described. The Ozon-Mir spectrometer measured solar radiation absorption along tangent paths in a large number of spectral channels within the range from 265 to 1130 nm at sunsets. Different stages of telemetric information processing are considered. The atmospheric radiative model used for computations and the algorithm of data inversion are discussed. Measurements in oxygen absorption bands provided an independent way of referring the data of transmission function measurements to heights. Errors in ozone content determination that are due to different factors are estimated. By and large, the experimental results correlate well with climatic data. At the same time, significant variations in the ozone content were observed. They may be explained by the natural variability of characteristics of atmospheric gaseous composition and also by retrieval errors.
