Statistical tests are performed on 30 years (1957–1986) of Dobson station data. The triple‐period (30, 20, and 8.6 months) extratropical QBO signal in ozone is found to be statistically significant. Earlier tests, based on 9 years of TOMS data, gave ambiguous results. We further suggest an objective method of extracting ozone QBO signal in the extratropics using a linear regression model.
