Global distribution of ozone is remotely sensed from the radiance measurements made by the Infrared Interferometer Spectrometer on board the Nimbus 3 satellite. As ozone is a good tracer of the atmospheric motions in the lower stratosphere and upper troposphere, it is used to infer the nature of upper air currents over southeast Asia and Africa during June and July, 1969. Significant ozone Minima over North India, and the deserts of Sahara and Middle East correspond to upper air high pressure systems over these regions. Ozone maxima are seen preferentially along the path of the strong easterly winds associated with the easterly tropical jet. These observations of atmospheric ozone demonstrate a potentially valuable way to follow the development of Southwest monsoon and the tropical easterly jet stream.
