First Announcement of the Colloquium

"25 Years of Research with the Aircraft FALCON"

March 5/6, 2001, Oberpfaffenhofen near Munich, Germany


The research aircraft FALCON has been taken into operation by DLR in the year 1976. Since then, the aircraft has been used very successfully in many research projects at national and, increasingly, at European level. Recently, representatives of the German atmospheric research community expressed the need for a new research aircraft with extended capacity in cruising altitude, range, and scientific loads. Therefore, a Colloquium will be organised which celebrates the Jubilee by showing up the results obtained, the international cooperation, and the needs and chances for the future. The lectures will be presented in English language.

The Colloquium will take place in Oberpfaffenhofen, near Munich, March 5 and 6, 2001, from noon to noon. The Colloquium will contain invited talks and an open poster session. For each poster contribution we ask to submit a one-page abstract by February 1, 2001.
