Upgraded Doppler Rayleigh lidar and comparisons with stratospheric radar. 1. Observations following initial system modifications

Presents lidar observations of density fluctuations in the presence of thin cloud and aerosol layers with complementary stratosphere/troposphere (ST) radar wind profiles. These observations followed the initial stage of a Doppler Rayleigh lidar system upgrade. These initial observations were made during the week of September 9-18, 1994, coincident with the Space Shuttle Lidar In-Space Technology Experiment (LITE). The experimental goals of the September 1994 run were twofold. The first goal was the characterization of the Doppler lidar wind profiling mode following the initial modifications, and prior to subsequent system upgrades. Secondly, the scientific goal was to extract dynamics (e.g. gravity and tidal waves) of the upper troposphere and stratosphere. The ST radar was run in a constant wind profiling mode throughout the entire run.
