Aeronomy satellites AEROS A and B: The assistance to the project by the project scientist

With the German-U.S. research satellite AEROS-A and the German satellite AEROS-B the most important aeronomic parameters in the upper atmosphere were measured between December 1972 and September 1975. Simultaneous observations of densities, composition, and temperatures of both the atmospheric neutral gas and the ionospheric plasma and, in addition, of the solar energy influx in the extreme ultraviolet was essential to allow for an integrated analysis of the aeronomic interactive processes. The responsibility within the project management for all scientific matters was with the project scientist, and this report is on his contribution to meet the goal of the mission. Also the experimental and mission aspects, the management organization, the project development, and the major science return from the AEROS program are explained.
