主　　题：gravity wave laser radar sodium layer spectrum 

摘      要：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 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 slpoes of ?2. 12 in the upper mesosphere when the associated density mean quantity of the day was used.
