The aim of our research and education program is to elucidate past events through the analysis of samples obtained from glaciers and growth rings of trees, and understand the present situation through the measurement and analysis of greenhouse gases, aerosol and air pollutants on various scales, ranging from the city level through to that encompassing the entire Earth. Our research also aims to predict future events based on a better understanding of environmental variation mechanisms and human activities.Koji Fujita / Kengo Sudo / Ritsu Uemura / Hitoshi Matsui / Ippei NagaoGlobal warming associated with recent increases in greenhouse gases is one of the most serious global environmental problems that we face today. To predict future trends in global warming and environmental variations, it is necessary to understand the mechanisms responsible for the maintenance and variation of climate. The aim of this laboratory’s basic and applied research/education is to understand the various physical and chemical processes related to climate/global environmental changes, as well as to understand and predict further changes in atmospheric composition, involving greenhouse gases, ozone and aerosols, and cryosphere variations.Urumu Tsunogai / Kazuo Osada / Fumiko Nakagawa / Atsuko Yamazaki / Osamu Abe / Tamihito NishitaHiroshi Tanimoto / Tuyoshi WatanabeAs exemplified by global warming and ozone depletion, the Earth’s surface environment is determined by biochemical cycles of light elements such as carbon, oxygen, nitrogen, and hydrogen. These cycles are also closely associated with life activities including those of humans. Aiming to acquire a comprehensive understanding of the biochemical cycles which occur in various time/space scales as well as an ability to predict the biochemical cycles, this research group observes the Earth using the latest techniques in the fields of atmosphere, marine, and land sciences. Our research themes include:・quantitative estimation of biochemical cycles amongst atmosphere, marine, and land environments (carbon and nitrogen),・interactions between life and the dynamics of Earth systems,・reproduction of the paleoenvironment and paleoclimate, and understanding of the mechanisms of their changes, and・development of Earth observation techniques such as isotopic mass spectrometry.Hidenori Aiki / Nobuhiro Takahashi / Kazuhisa Tsuboki / Tetsuya Hiyama / Michihiro Mochida /Naoyuki Kurita / Taro Shinoda / Hirohiko Masunaga / Hatsuki Fujinami / Sho Ohata / Yoshihisa Mino This group conducts comprehensive studies of the time/space structure and changes in the water cycle covering the atmosphere, hydrosphere, and biosphere, including material and energy cycles. Research themes include: • Extreme weather phenomena such as typhoons• Cloud and precipitation systems• Interaction between vegetation and weather systems• Atmosphere-ocean-land interaction and relation with marine ecosystems• Dynamic state and behaviors of aerosol and their effects on climate The faculty consists of teaching staff from the Divisions for Meteorological and Atmospheric Research and Land-Ocean Ecosystem Research of the Institute for Space-Earth Environmental Research at Nagoya University. Classes with* are provided by cooperating institutions.
