The wind is one of the fundamental meteorological elements describing the atmospheric state, such as pressure, temperature, humidity. Global wind profile observation is important to significantly improve the initial conditions essential for numerical weather prediction (NWP), air quality forecasts, climate studies, and various meteorological studies. Current global wind observing systems do not always satisfy user requirements of wind profile observation for NWP. ESA successfully launched the first space-based Doppler Wind Lidar Aeolus in August 2018. The impacts on NWP though global wind profiles obtained by Aeolus showed moderate/strong impacts on NWP. NWP and science communities expect a follow-on space-based DWL mission. The working group on Japanese space-based DWL is making a feasibility study on a space-based IR coherent DWL (CDWL) for future global wind profiling. In the presentation, we will report on details on feasibility studies for the CDWL conducted in 2020.
