Description
Summary:An important parameter in the modelling of polar cap ionospheric phenomena relating to scintillations and small scale irregularities is the thermospheric wind. The magnitude and direction of the flow of the neutral atmosphere determines how quickly these features of the polar cap morphology develop and grow. The AFGL contract was awarded to support the construction and installation of an automatic instrument designed to observe automatically thermospheric winds and temperatures at Thule Air Base in Greenland. The observatory was successfully operated throughout the 1985/1986 winter between early December 1985 and 1 April 1986. This report presents the description of the instrumentation and a set of plots showing the reduced set of observations for the clear nights in this period. Keywords: Thermosphere; Polar ionosphere; Fabry-Perot interferometer; Spectrophotometry; Atmosphere dynamics and thermodynamics.
