Scientific paper

Incoherent scatter radar measurements previously obtained at Millstone Hill in New England are combined with mass spectrometer/incoherent scatter model neutral densities to derive exospheric temperatures and the neutral wind component at 300 km parallel to the magnetic field. These calculated quantities are used to determine the neutral horizontal pressure gradients and winds in a dynamical model of the thermosphere above the radar site. Extension of the model to find the vertical velocity via the continuity equation is considered, and the uncertainties involved in the neutral wind determinations are examined. Representative summer and winter results are compared with results obtained by use of empirical models. Seasonal wind variations of 1970-1971 are characterized. The mean equatorward winds, large annual variations, and average downward velocities are consistent with a global circulation model presented by Dickenson et al. (1977) and require the existence of significant heating of the thermosphere at high latitudes.
