After more than four decades of international research and development in Doppler Wind Lidar, the Atmospheric LAser Doppler INstrument (ALADIN) on ESA's Aeolus mission is the first system to demonstrate direct measurement of vertically resolved wind profiles from space.  While international studies are already demonstrating the positive impact of Aeolus lidar observations on weather forecasts, the ALADIN mission life is limited to a maximum of three years.  The same year as the Aeolus launch, the NOAA Satellite Observing System Architecture (NSOSA) study listed 3D-Winds as one of the top observational objectives for future weather architectures and the National Academies Earth Science Decadal Survey (ESDS) listed Atmospheric Winds as one of the top targeted observables.  The Optical Autocovariance Wind Lidar (OAWL) approach developed at Ball Aerospace, with funding support from NASA, provides a validated, high-TRL, and reduced-risk U.S. option for an Aeolus follow-on. This seminar will discuss the characteristics of Doppler wind lidar observations, compare wind lidar to other wind-observing methods used in numerical weather prediction, describe what the OAWL approach offers relative to Aeolus, and provide a roadmap for achieving a U.S. space-based wind lidar as part of a future operational weather architecture.
