DEVELOPMENT OF A HYPSOMETER FOR ATMOSPHERIC SOUNDING.

Abstract

This report describes the development of a descent hypsometer for use at high altitudes in the atmosphere. The basic concept employed is to measure the equilibrium temperature of a boiling liquid and its pure vapor while the latter is in equilibrium with the ambient pressure. ' The ambient pressure is then determined from the known vapor-pressure temperature characteristics of the liquid, or by direct calibration. This sensor can be used in rocketsondes and dropsondes. It is simple, reliable, and can be produced economically even in small quantities. When prepared for production in moderate quantities, the sensor will have a very attractive cost. It is small, light, and has simple sampling requirements. This report describes all the aspects of development, design, and laboratory and environmental tests. Sonde field tests, which were successfully completed, are described in another report. (Author)
