Between June 10 and July 19, 1987, a total of 26 falling spheres have been successfully launched from the Andøya Rocket Range in Norway (69°N, 16°E). From precision radar tracking of the sphere trajectories, 26 temperature profiles were derived for the altitude range 50–90 km. A mean profile, calculated from all data obtained, shows the mesopause to be at an altitude of 88 km and at a temperature of 129±6 K. This mesopause temperature is considerably lower than predicted in some recently developed reference atmospheres. In the middle and upper mesosphere, each of the 26 profiles exhibits a lapse rate close to −6 K/km. These results are compared with parameters obtained previously in winter at the same site.

Uplift of the Rhenish Massif can be demonstrated by means of the stream-made river terrace system that accompanies the Rhine river and its tributaries along their way through or within this part of the Variscan fold and thrust belt. The height difference between a former valley floor, especially that of the Younger 'Hauptterrasse' (Main Terrace), and the recent one allows to quantify the uplift by the amount of downcutting erosion. The uplift velocity increased just after the BRUNHES / MATUYAMA boundary, i.e. about 0.8 Ma B.R Since that time, a domal uplift of more than 250 m is documented in the eastern Hunsriick and in the south-eastern Eifel.The area of this maximum height anomaly is situated just between the Eastand West-Eifel Quaternary volcanic districts. Thus, causal connections are supposed. The domal uplift is affected by normal faulting partly inherited since Tertiary rifting.
