Winds at altitudes up to 80 kilometers

Wind data have been collected at altitudes between 30 and 80 km in the course of six rocket flights at White Sands Proving Ground during 1950 and 1951. Additional wind data to altitudes as high as 40 km have been obtained since 1948 by tracking radiosondes carried aloft by special high-altitude balloons launched at Belmar, New Jersey. Day-to-day wind changes at 30 km are discussed. From the mean wind structure, inferences are drawn as to upper atmosphere temperatures at higher latitudes.
