Additional information

Atsumu Ohmura was Full Professor of Physical Geography at the ETH Zurich, starting in 1983. He retired end of March 2007.

Born in Masago-cho, Hongo-ku, Tokyo, in 1942. Educated at the Faculty of Science,

University of Tokyo (B.Sc. 1965), at the Faculty of Graduate Studies and Research of McGill University, Montreal (M.Sc. 1969) and at the Federal Institute of Technology (ETH) in Zurich (Dr.sc.nat.), Ohmura was a climatologist with special interest in the energy budget at the earth's surface. Both experimental and theoretical approaches were taken. For the field experiments, he was engaged in the works in the Canadian High Arctic, Baffin Bay, Greenland, the Alps, Tian-Shan and Caribbean Sea. In theoretical area, the contributions were made in atmospheric radiation, atmospheric boundary layer and the radiation transfer in snow and ice. He integrated his works in discoveries of the missing absorption of solar radiation in the atmosphere, the decadal variation of solar radiation (Global Dimming, and Brightening), missing emission of the atmospheric long-wave radiation, and the inbalance of the energy gudget owing to the absorption by the ocean and melt of the cryosphere. These developments are summed up in the presentation of the new global energy balance of the climate system. The principle of the energy balance was applied for understanding the change of glaciers in various climatic regions, based on the equilibrium line/climate relationship. He has been engaged in climate model development mainly in the field of radiation. He is still seeking for the relationship between the global climate and entropy change in the planet, which remains still inconclusive.

He was elected fellow of the Arctic Institute of North America in 1988.
