Abstract
The structure and state of the stratosphere and the mesosphere have been measured in the central tropical Pacific under a composite program of meteorological measurements. Density and temperature profiles between the altitudes of 30 and 120 km have been obtained, and wind velocities between the altitudes of 30 and 60 km have been derived from the radar track of an inflated sphere ejected from a rocket. The wind data have been supplemented by profiles from conventional meteorological rockets. Water vapor measurements by balloon-borne frost-point hygrometers have provided accurate humidity measurements in the upper troposphere and lower stratosphere.
