As many of you have remembrances, souvenirs and anecdotes, we propose you to send the ones you’d like to share with the community by filling in them in on Aviso+ web site, as prepared by Vinca Rosmorduc, at: https://www.aviso.altimetry.fr/en/news/sympathy-messages-for-michel-lefebvre.html (note that moderation will be done, so your message won’t appear right away) We will convey your messages to his family. Sincerely, Sophie Coutin-Faye CNES, Head of Altimetry and Argos projects ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Le 22 juil. 2019 à 17:35, Fu, Lee-Lueng (US 3200) a écrit : Dear Colleagues: It is with great sadness to inform you of the passing of Michel Lefebvre on Sunday, July 21, at an age of 85. Michel was instrumental in the early 1980s in the establishment of the TOPEX/POSEIDON (T/P) Mission. He was a geodesist with a profound vision of the potential of satellite altimetry and had been a key figure in pushing the boundary of altimetry as well as building the series of missions leading to today’s international altimetry constellation. I recall in the 1991 T/P Science Team Meeting in Toulouse, while the mission planners were struggling to meet the 13 cm requirement for orbit determination, Michel boldly posed a 2 cm challenge. It proved a monumental achievement of the mission, leading to fundamental advances in the study of global ocean circulation and sea level change from altimetry. As high precision altimetry neared reality, Michel became a strong force for implementing the World Ocean Circulation Experiment, both to exploit and enhance T/P. Michel was a source of wisdom for oceanography and geodesy until Parkinson’s disease had finally consumed his body and mind in recent years. He was a dear friend and inspirational colleague. I had the privilege of knowing him and working with him. He will be sorely missed by many of us who knew him personally. For those who didn't know him, I hope you will recognize his tremendous contributions to the field in which you have built a career with the wonders of satellite altimetry.
