| Zusammenfassung |
| The Atmospheric Chemistry Experiment-Fourier Transform Spectrometer (ACE-FTS)
aboard the Canadian satellite SCISAT (launched in August 2003) was designed to
investigate the composition of the upper troposphere, stratosphere, and mesosphere.
ACE-FTS utilises solar occultation to measure temperature and pressure as well
as vertical profiles of over thirty different chemical species including; O3, H2O,
CH4, N2O, CO, NO, NO2, N2O5, HNO3, HCl, ClONO2, CFC-11, CFC-12, and
HF. Global coverage for each species is obtained approximately over one year and
with a vertical resolution of typically 3-4 km. A quality-controlled climatology has
been created for each of these 14 baseline species, where individual profiles are
averaged over the period of 2004-2009. Measurements used are from the ACE-FTS
version 2.2 data set including updates for O3 and N2O5. The climatological fields are
provided on a monthly and seasonal basis (DJF, MAM, JJA, SON) at 5 degree
latitude and equivalent latitude spacing and on 33 pressure surfaces (31 of which
are defined by the Stratospheric Processes And their Role in Climate (SPARC)
Chemistry-Climate Model Validation Activity (CCMVal)). The equivalent latitudes
are derived from the GEOS-5 analyses interpolated to the time and location of
each ACE occultation. As an example of how the climatology data can be used, we
present some preliminary results concerning the behaviour of some key species in
the upper troposphere/lower stratosphere and Arctic regions such as water vapour. |
