TWiLiTE
Tropospheric Wind Lidar Technology Experiment

The Tropospheric Wind Lidar Technology Experiment (TWiLiTE) is an airborne lidar system that profiles tropospheric winds. It measures 355-nm lidar backscatter to retrieve wind profiles from the surface to 18 km. TWiLiTE has a vertical resolution of 250 meters and a pulse repetition frequency of 200 Hz. It was designed for autonomous operation on high-altitude aircraft such as the NASA ER-2 and WB-57.
