Abstract : Seasonal and latitudinal variability of density between 30 and 68 kilometers is presented. These data were derived from irect temperature and height measurements made with meteorological rockets fired at White Sands Missile Range, New Mexico, and Fort Churchill, Canada, uring 196061 Meteorological Rocket Network and R+D activities. Some of the more significant features are the wider seasonal range at northern latitudes, the absence of significant latitudinal variation during the summer, the greater variation in winter at each stati n and the over-all variation at a particular altitude that can occur -- as much as fifty percent in some cases. The need for both seasonal and latitudinal standard atmospheres where standards are required is clearly demonstrated. Also, the feasibility of making timely density measurements for such problems as re-entry vehicle drag, etc. is evident. (Author)
