Special issue}, month = {Mar}, note = {P(論文), A new movement to establish a permanent environment observatory at Summit in Greenland is under way between US and Europe. The initial motivation was to observe exchange processes between the atmosphere and the ice sheet surface to obtain the basic knowledge for the ice-core interpretation. It was, however, soon recognised that the objective necessitated the observations not only on the ice sheet surface, but also for the entire atmosphere including the middle atmosphere and the thermosphere. It became also obvious that the near-surface snow and firn layer should be investigated. To reach the goal the observations should be carried out year-round for a number of years. By the beginning of 1996 the idea was developed to establish an observatory for the integrated environment observation. As the first step a feasibility study for over-wintering at Summit was carried out during the 1997/1998 season with a four-man team. The project started its first year's operation in April 2000 and expects to carry out proposed observations for at least three years, until the final decision is made regarding the precise nature of the "permanent" observatory. The entire observation programme is multi-disciplinary. The author has been participating in the planning of the observatory from the start of the project. The present article was prepared to present an overview of the planned activities at the prospective observatory with emphasis on the field which the author has been primarily engaged in.}, pages = {153--159}, title = {Summit Greenland environment observatory (report)}, volume = {54}, year = {2001} }
