By measuring the mean shifts of hundreds of lines in solar occultation spectra obtained at satellite altitudes, relative wind speeds along the lines of sight of the rays can be obtained with precisions of 5 m/sec or better at altitudes up to 100 km. It is necessary to obtain more accurate line positions or to introduce a gas sample for frequency calibration if absolute wind speeds are to be obtained.
