Abstract

A statistical analysis is presented of Umkehr measurements of 32-46 km ozone levels. The purpose of the analysis is to estimate long-term trends related to man's release of chlorofluorocarbons (CFC's) and to empirically assess the quality of the Umkehr data for detecting such trends. The analysis fails to detect the decrease in upper-stratospheric ozone predicted to occur by atmospheric models. The Umkehr records indicate that 32-46 km ozone in the north temperate zone has been increasing since 1956 with a possibly lesser rate since 1970. The variability in trend estimates among stations is sufficiently large that overall trends are not statistically significant. The use of Umkehr records for detecting an impact of CFC's is contingent on first understanding the nature of observed trends in upper-stratospheric ozone prior to 1970.
