Abstract
This paper summarizes the dynamical information obtained in the lower thermosphere during the Energy Budget Campaign, by three experimental techniques: rocket-borne falling spheres instrumented with accelerometers and Tri-Methyl-Aluminium (THA) trails, and from a ground based Fabry-Perot interferometer. Winds of 200-400 m/sec, accelerated by the momentum and energy inputs from the magnetosphere, were observed during the ‘B‘and ‘A2‘salvos (15/16 Nov 1980 and 30 Nov/I Dec resp.), with perturbations as low as 100 km altitude during the ‘B‘salvo. A global model has been used to simulate the wide-scale consequences of these disturbances, and to aid estimation of the integrated energy and momentum inputs.
