ABSTRACT

Balloon-borne in situ observations of water vapor and ozone in the upper troposphere and lower to middle stratosphere provide invaluable data to study atmospheric processes in this part of the atmosphere. Requirements for relatively low cost instruments and the need for routine observations place high requirements on instrument design, production, data quality control, and data management. In this presentation, I will describe some basics of the Cryogenic Frostpoint Hygrometer (CFH) to measure routine water vapor and the Electrochemical Ozone Sonde (ECC) to measure ozone. I will describe some of the measurement programs that have taken place over the recent years and will discuss the lessons we have learned about the processes in the upper troposphere and lower to middle stratosphere from these important observations.
