Abstract

Wind is one of fundamental meteorological elements describing the atmospheric state. Global wind observation is important to improve the initial conditions essential for numerical weather prediction (NWP), climate studies, and meteorological studies. A space-based Doppler Wind Lidar (DWL) would be a useful approach for global wind profiling. It is important to evaluate wind measurement performance before launch of space-based DWL. We develop coherent and direct-detection DWL simulators to investigate measurement performance on wind. In the paper, we describe the development of the two DWL simulators for the future space application.
