Determining Wind Speed, Temperature, and Water Vapor Content in the Mesopause by an Active Sensing Method

The possibility of simultaneous measurement of wind speed, temperature, and concentration of H2O molecules within the mesopause during its active sensing at submillimeter wavelengths using two satellites is verified. Expressions are derived that in explicit form relate the characteristics of the medium to the optical depths of the sensing path at the harmonic frequencies of an amplitude-modulated signal, whose carrier frequency coincides with the center of the water vapor resonance line.
