Future Space-Based Doppler Wind Lidar Winds

The unique European Space Agency (ESA) Earth Explorer Aeolus Doppler Wind Lidar (DWL) is a success with beneficial impacts in weather and climate. At the IGARSS ‘21 venue we will share our results internationally and present initial studies that look into an operational Aeolus follow-on mission and describe lessons learned on the instrument, data processing and application of the winds. The ESA Aeolus mission now demonstrates the unique benefits of direct measurements of the atmospheric wind fieldon atmospheric dynamical analyses and forecasts. The many lessons learned from the Aeolus instrument development, its operation and data processing development are being exploited to help develop the requirements and design of an Aeolus follow-on mission in order to further enhance its application benefit globally. An overview of preliminary Aeolus and future DWL requirements will be presented to initiate a discussion with the international community gathered at IGARSS ‘21.
