Sodium layers (75–105 km) were measured by Na lidar on three nights from 1 to 3 of March 1996. The lidar data were used to calculate the Na density profiles and the atmospheric density spectra. The vertical wave number spectra exhibit power-law shapes with average slopes of −2.38 and magnitude at m =2π/(3 km) of 8.40 × 105 (m2s−2)/(cyc/m) in the mesopause region.
