Abstract:
On the first leg of the journey, the northern hemisphere showed higher ozone mixing ratios than the southern hemisphere. Slightly increased ozone mixing ratios were observed in the ITCZ, however, with an ozone minimum to the south. The latter can be caused by photochemical ozone destruction at conditions with of intense radiation and low vertical mixing. During the return journey, the ozone mixing ratio was low at all latitudes and there were no differences between the northern and southern hemispheres. In the ITCZ, the measurements were disturbed by ship exhaust.
