Abstract:

This report covers work done on solving some basic problems of stratospheric humidity measurements, in particular the contamination of the air sample by water vapor desorbed from the flight vehicle and instrument package. Results of theoretical and experimental studies of frost-layer dynamics are presented and their implications for automatic frost-point hygrometers are discussed. Instruments used on the program are described, and data from three stratospheric balloon soundings are presented and analyzed from a contamination standpoint. An optimum water-vapor sounding technique is suggested, along with recommendations for further study. Author
