		| Scope | Present conveners (members of Japan Meteorological Society) are carrying out elucidation, through observation and modeling endeavors in cooperation with environmental researchers in the company of radiochemists, of transportation and deposition onto terrestrial environment of radionuclides emitted by the Fukushima Nuclear Accident in 2011 March as well as the aerosol characteristics which carried the radionuclides. We are aiming at to obtain better understanding and scope for the short- and long-term environmental radioactive pollution. In this connection the Fukushima Nuclear Accident serves radioactive tracers for geoscientists. The improvement of chemical transport models applied to short-range weather forecast and long-term climate change is thus intended in this project, and the comprehensive research development is designed for covering the atmospheric, oceanic and terrestrial interactions. Therefore, on the present international symposium occasion, with cooperation of the domestic and foreign atmospheric and terrestrial researchers concerned, pieces of the state-of-the-art knowledge will be assembled on the consequences and temporal changes of atmospheric and terrestrial environmental pollution caused by the Fukushima Nuclear Accident. The lively discussion on future challenges and directions of the researches are welcomed. Note that the transparencies should be in English. |
