Shuttle-derived densities in the middle atmosphereNASA Space Shuttle flights have furnished a basis for the derivation of middle-atmosphere densities with unprecedented vertical resolution; an archival data base is now available that furnishes extensive information for the evaluation of existing model estimates for latitudinal and seasonal effects, as well as the improvement of mean monthly predictions. The High Resolution Accelerometry Package results yield extensive large-amplitude, low-frequency density variations throughout the thermosphere. The Inertial Measurement Unit results show abrupt density shifts at all latitudes, with visible shears being observed that can be correlated to summer activity.
