My career is dedicated to all aspects of satellite wind measurements. From new concepts, cal/val, wind retrieval optimization, operational production to applications and training in weather nowcasting. It involves data science, machine learning, NWP data assimilation, climate data records, ocean forcing, marine boundary layer and air-sea interaction research. I'm now leading a group on active remote sensing from satellites using radar and lidar for ocean winds, clouds and aerosol, and involved in the ESA Aeolus, EarthCare and HARMONY missions and participating in the EUMETSAT and Copernicus ground segment services. I am an IEEE fellow (http://www.ieee.org/) and my publications are on Google Scholar, ResearchGate and Orcid. You can also find some material on YouTube.

Clearly, climate change produces more extreme weather and associated ocean anomalies, hence calling for 1) improved weather advisories in the future for loss reduction and 2) for climate projections for adaptation. A better understanding of earth system dynamics may provide benefits in both areas. Earth-orbiting satellites have this century been proven indispensible for monitoring the earth system, both for tracking the weather and for understanding earth system processes. The value of satellite observations is being further exploited by novel future satellite missions. An overview of needs and EO systems will be provided. Winds determine weather, hurricanes, waves and surges, energy production, ocean forcing, heat and carbon budgets, sea ice decline, climate change, andsoforth. Hence, satellite winds are extensively used by marine forecasters, in NWP, by oceanographers, wind engineers, off-shore industry, safety authorities and climate scientists alike. More dynamical information is becoming available due to new and extending virtual constellations of satellite wind-sensing instruments. This new information is hence beneficial for above-mentioned applications. However, it is clear that a remaining gap in the understanding of earth system dynamics remains in the intricate coupling between the atmosphere and the ocean and in the presentation this aspect will also be further elaborated. As an example of the interplay between different professional disicplines, a furthermore interesting and related topic is how to measure and monitor winds in hurricanes?
