| Zusammenfassung |
| The SCIAMACHY/ENVISAT satellite instrument (2002-12) has monitored Earth’
atmosphere globally for almost one decade. In its limb viewing geometry, it measured the
vertical profiles of the atmospheric limb scatter. O3, NO2, and BRO are among the retrieved
species. Their vertical profiles are obtained in 1 km altitude steps. Longterm changes as well
as periodically varying features are reflected by the resulting time series. The longterm
changes are statistically described by trends.
The trend profile of SCIAMACHY limb O3 extends throughout the stratosphere and is a
function of the latitude. There are contrasts and parallels between the tropics and the
mid-latitudes. With O3 being in the focus of interest for several decades now, there is a range
of parallel measurements. Thus, the quality of the SCIAMACHY ozone trends is confirmed
by inter-instrumental comparisons. There are contemporary satellite instruments as well as
different measurement techniques.
In our talk, we further present trend profiles of NO2 and BRO. Being crosslinked through
chemical reactions, their trend profiles are potentially related among each other and to O3. |
