Gérard Mégie
Gerard Jean-Jacques Mégie (born June 1, 1946 in Paris ; † June 5, 2004 ibid) was a French physicist in the field of atmospheric research and chairman of the research organization Center national de la recherche scientifique (CNRS).
Career
Mégie studied from 1965 at the École polytechnique . From 1968 to 1974 he worked for the state space agency CNES . In 1974 he joined the CNRS. In 1976 he received his doctorate in natural sciences (Docteur ès Sciences) . In the following years he continued his career in the CNRS. In 1988 he became a professor at the Université Pierre et Marie Curie (UPMC) in Paris . From 1996 to 2000 he was Director of the Aeronomic Service (Service d'aéronomie), jointly operated by the CNRS, UPMC and the University of Versailles , of which he had previously been Deputy Director since 1984.
Mégie was the founder and from 1991 to 2000 director of the inter- institutional Pierre-Simon Laplace Institute (named after the 18th century scholar of the same name ). In 2000 he became chairman of the CNRS, an office which he held until his death.
Services
Mégie's research area was the physics and chemistry of the earth's atmosphere using both experimental and theoretical methods. He first investigated the origin of metallic species in the upper atmosphere. He then devoted himself to research into anthropogenic changes in the ozone layer in the stratosphere .
The focus of Mégie's work was on the one hand the development of new measurement methods for atmospheric parameters by means of laser remote measurement, for example lidar methods, on the other hand the modeling of natural fluctuations in the ozone content in the atmosphere and its changes as a result of human activity.
He contributed to the development and commissioning of numerous ground, air and satellite-based measurement systems and coordinated several measurement campaigns on ozone concentrations in the Arctic and Antarctic .
Most recently, he devoted his research to the chemical equilibrium processes in the troposphere under the influence of air pollution by photooxidants as well as the more general connections between changes in the chemistry of the earth's atmosphere and the problems of climate change . He was also involved in interdisciplinary projects on the economic and social consequences of environmental problems.
honors and awards
During his lifetime
In 1987 Gérard Mégie was awarded the CNRS silver medal. In 1992 he received the Grand Prize (Congress award) of the International Union of Air Pollution Prevention and Environmental Protection Associations , and in 2001 the Grand Prize of the Atomic Energy Commission of the French Academy of Sciences . The European Geosciences Union awarded the Alfred Wegener Medal in 2004 and made him an honorary member.
In 1998, Mégie was made a member of the Institut Universitaire de France . He was also a member of the French Academy of Sciences and other French and international learned societies .
Mégie was a knight (Chevalier) of the Ordre national du Mérite and the Legion of Honor .
Posthumously
The Academy of Sciences has been awarding a prize named after him since 2005, the Prix Gérard Mégie . It is endowed with 15,000 euros and is awarded every two to three years for outstanding work in the field of research into the atmosphere, the oceans, the cryosphere or their interactions. Prize winners can be an individual scientist or a research group from France or abroad.
In February 2008 a memorial plaque was erected in his honor in Adélieland, Antarctica . To mark the occasion, the French Southern and Antarctic Lands issued a stamp dedicated to him.
Publications
In the course of his career, Mégie published around 240 scientific articles, including over 100 in international peer-reviewed journals, as well as several books, one of which (Ozon) was also translated into German.
