| Zusammenfassung |
| The Atmospheric Chemistry Experiment (ACE) mission was launched in August
2003 to sound the atmosphere by solar occultation. Carbon monoxide (CO), a
good tracer of pollution plumes and atmospheric dynamics, is one of the key
species provided by the primary instrument, the ACE-Fourier Transform
Spectrometer (ACE-FTS). This instrument performs measurements in both the CO
1-0 and 2-0 ro-vibrational bands, from which vertically resolved CO
concentration profiles are retrieved, from the mid-troposphere to the
thermosphere. This paper presents an updated description of the ACE-FTS
version 2.2 CO data product, along with a comprehensive validation of these
profiles using available observations (February 2004 to December 2006). We
have compared the CO partial columns with ground-based measurements using
Fourier transform infrared spectroscopy and millimeter wave radiometry, and
the volume mixing ratio profiles with airborne (both high-altitude balloon
flight and airplane) observations. CO satellite observations provided by
nadir-looking instruments (MOPITT and TES) as well as limb-viewing remote
sensors (MIPAS, SMR and MLS) were also compared with the ACE-FTS CO
products. We show that the ACE-FTS measurements provide CO profiles with
small retrieval errors (better than 5% from the upper troposphere to 40
km, and better than 10% above). These observations agree well with the
correlative measurements, considering the rather loose coincidence criteria
in some cases. Based on the validation exercise we assess the following
uncertainties to the ACE-FTS measurement data: better than 15% in the
upper troposphere (8–12 km), than 30% in the lower stratosphere (12–30 km), and than 25% from 30 to 100 km. |
