TWiLiTE
Tropospheric Wind Lidar Technology Experiment

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