Lidar studies of sporadic sodium layers, gravity waves and density spectra in the mesopause and stratopause regions at Urbana and Arecibo

The high spatial and temporal resolution of the UIUC CEDAR lidar and new processing techniques have significantly improved the study of vertical and temporal structures of the middle atmosphere. This thesis paper first presents what are believed to be the first observations of meteor ablation trails with a lidar. Next, the simultaneous observations of a sporadic E layer by the Arecibo 430 MHz incoherent scatter radar and a sporadic Na layer by the UIUC CEDAR Na lidar are presented. The high correlation between the altitude and abundance variation of the two layers is discussed.
