Sodium lidar studies of the horizontal variability of gravity waves in the mesosphere

A data analysis technique for determining gravity wave intrinsic parameters is presented. The intrinsic parameters include the horizontal and vertical wavelengths, period, and wave propagation direction. The technique involves measuring the altitude variations of the wave induced density perturbations in the mesosopheric Na layer. The intrinsic horizontal wavelength of a wave observed with an airborne lidar in November 1986 was estimated to be about 85 km, and the vertical wavelength was 4.1 km. The intrinsic period was about 1.7 hours, and the propagation direction was almost due south.
