Ground-Based DWL Laboratory: Frequency Stability


We examined three poly-pulse processed data sets to evaluate the frequency stability of the NASA/MSFC Doppler lidar wind returns from several stationary targets such as a mountain, building 4200 and a tower.

Range versus time LOS wind velocity plots for returns off the building (~2.5 km).

Line-of-sight velocity, at range gate 8, as a function of time for returns off the same building.

The LOS velocities varied with a of ~ .05 m s-1.
