| Zusammenfassung |
| The ACE-FTS (Atmospheric Chemistry Experiment – Fourier Transform
Spectrometer) solar occultation instrument that was launched onboard the
Canadian SCISAT-1 satellite in August 2003 is measuring vertical profiles
from the upper troposphere to the lower mesosphere for a large number of
atmospheric constituents. Methane is one of the key species. The version
v2.2 data of the ACE-FTS CH4 data have been compared to correlative
satellite, balloon-borne and ground-based Fourier transform infrared remote
sensing data to assess their quality. The comparison results indicate that
the accuracy of the data is within 10% in the upper troposphere – lower
stratosphere, and within 25% in the middle and higher stratosphere up to
the lower mesosphere (<60 km). The observed differences are generally
consistent with reported systematic uncertainties. ACE-FTS is also shown to
reproduce the variability of methane in the stratosphere and lower
mesosphere. |
