Millimeter wave satellite tomography of the Earth's ozone layer

摘要

A new active radiosounding method is suggested for global satellite monitoring of a Earth's ozone layer. The method is based on millimeter wave transmission along the path between two satellites, one carrying a transmitter, the other one carrying a receiver. In the case of paths passing over 10 km above the Earth's surface, the influence of oxygen and water vapor absorption is absent, therefore signals of ozone absorption for 2 to 3 mm wavelength spectral lines are free from any interference. In comparison with well-known radiometry, the method is distinguished by its particular precision and resolution.
