The performance characteristics of the electrochemical and chemiluminescent ozonesondes were investigated through analysis of comparative ascents. A direct intercomparison of short duration was made at Boulder, Colorado, in October 1964. Further comparison was obtained by analysis of ascents made on the same day on many individual days using the electrochemical instrument at Boulder, Colorado, and the chemiluminescent instrument at Fort Collins, Colorado. Good agreement was found between the two methods of ozone measurement. Observed differences in the comparative profiles obtained in the October test series were generally within a few nanobars partial pressure. Similar results were obtained from the Boulder‐Fort Collins data comparison. However, this analysis confirmed the fact that a correction is required for a systematic loss of sensitivity with time in the chemiluminescent‐type sonde ascents in the winter and spring of 1963–1964.
