摘要：
Sodium layers (75–105 km) were measured by Na lidar on three nights during March 1–3, 1996. The lidar data were used to calculate the relative atmospheric density perturbations and their spectra. The average r. m. s. density perturbations for early March at Wuhan are 5 %. The vertical wave number spectra exhibit power-law shapes with an average slope of -2.23 in the upper mesosphere when the associated mean density quantity of the day was used.
