The TWiLiTE (Tropospheric Wind Lidar Technology Experiment) airborne Doppler lidar was developed as an ESTO funded IIP instrument over the three year time period beginning in August 2005. The TWiLiTE instrument is designed for autonomous operation on NASAs high altitude research aircraft, such as the ER-2, WB-57 or Global Hawk. Flight testing and validation of TWiLiTE is a critical step forward for direct detection Doppler lidar on the path to a space based global 3DWinds Mission


Mission Status

The TWiLiTE Team is back from field work at Palmadale, California. Several engineering flights and a successful science flight were conducted aboard an ER-2.
