Seasonal trends of temperature, density, and pressure to 67.6 km obtained with the searchlight probing technique

During the period 29 May to 23 October 1952, 90 sets of measurements were acquired using the searchlight probing technique. Treatment of the data yielded density, temperature, and pressure information to 67.6 km. These results are discussed relative to seasonal trends. An over-all average for the period is submitted for the three parameters. The temperature profile obtained for pre-dawn, 22 October 1952, is compared with rocket, anomalous sound, and radiosonde temperature measurements, all carried out within a 14-hour period and a 300-mile radius. Good agreement is evident among the four methods.
