| Zusammenfassung |
In this paper, the stellar occultation instrument GOMOS is compared with
ozonesondes from the SHADOZ network. We only used nighttime O3 profiles
and selected 8 Southern Hemisphere stations. 7 years of GOMOS datasets (GOPR
6.0cf and IPF 5.0) and 11 years of balloon-sondes are used in this study. A
monthly distribution of GOMOS O3 mixing ratios was performed in the
upper-troposphere and in the stratosphere (15–50 km). A comparison with
SHADOZ was made in the altitude range between 15 km and 30 km.
In the 21–30 km altitude range, a satisfactory agreement was observed between
GOMOS and SHADOZ, although some differences were observed depending on the
station. The range for monthly differences generally decreases with
increasing height and is within ±15%. It was found that
the agreement between GOMOS and SHADOZ declines below ~20 km. The
median differences are almost within ±5%, particularly above 23 km.
But a large positive bias was found below 21 km, in comparison to SHADOZ. |
